    You can create a struct that contains the information structure that you want to pass to the UDFB. It is more logical to pass a struct with 50 members other than passing 50 inputs. Think of how the ladder element that accepts the 50 inputs will look like. it will start at the benining of the screen, and you would have to scroll few pages down in order to see its end.

    Download the attached Rar file, and extract the files to UniLogic installation directory. This means that the "UniLogic Diagnostics.exe" (and all the other files) must be placed in the same directory where "Unitronics.Shell.UI.exe" is located (usually at: "C:\Program Files (x86)\Unitronics\UniLogic\") After you've extracted the files, run "UniLogic Diagnostics.exe" and click on Diagnose. Most chances that it will show "SQL Instance" as one that has problems. In case it find problems, the "Fix" button will become enabled. Click on Fix, and the program will attempt to fix the problem, and then it will re-diagnose the problems to confirm that they are fixed. Please tell me what problems it found . Also tell me if it managed to fix the problem that you're experiencing with UniLogic (that it is stuck in loading components). Thanks. UniLogic Diagnostics.rar

    If it is really bad I've been known to hang an electrolytic capacitor between the analog input and 0V. I'm not kidding. Something like 10 uF @ 25V. Joe T.

    The USB in the UniStream acts as an Ethernet card (while in Vision PLC, it acts as a serial port). The USB of the UniStream is an RNDIS device, and for getting // assigning the IP address of the PLC over the USB-Ethernet an uPnP protocol is used. If the firewall blocks the uPnP handshake between windows and the PLC, then UniLogic will not be able to get the IP Address and communicate with the PLC.

    Yes, it was already implemented and would be available on the next release of UniLogic.

    Hi All I purchased this device on ebay. The model number is "VAP11G Bridge Cable Convert RJ45" (probably many alternatives available) Cost around €15.00 Works a treat on unistream. Plug in the ethernet and power via the USB port. PLC can now be programmed with the panel door closed over wifi. Should also work with Vision but you would need a power bank or 5v power supply.

    Continuity is easy - just connect +24V to one side of the wires one at a time and see if you get it on the other side. If you have a bundle to check you can switch wire feeds in with relays and make sure you only get one signal on a DI module connected to all wires. The RTD module only returns temperature from a resistance of about 25 ohms to 267 ohms. You could reverse-calculate the resistance, but I don't think this is the range you're looking for. Resistance is not so easy. Many moons ago I rolled my own ohmmeter with a DC power supply, current limiting resistors, voltage inputs on an analog module, and current sensors into another module. I was trying to measure to .01 ohm resolution on wire to make fuses and it kind of turned into a trainwreck. I learned about thermal drift of a multi-component system the hard way - I could not keep the thing calibrated. I eventually bought a really nice four-wire ohmmeter with a serial port and multiplexed it between the wires under test - the manufacturer liked it so much they asked if I would write an app note about it- https://www.tegam.com/wp-content/uploads/2015/10/AN103.pdf So this is an area I actually know a little more than the average bear about. This approach may be overkill for what you're trying to do. Can you be very specific about what you want? Joe T.

    I'm convinced this is delusional. CDs were originally pretty bad because sound engineers failed to properly tailor the sound for the new media and instead used the equilization curves for vinyl with insufficient modification. That's no longer the case. Nowadays, the abysmal compression of MP3s may be worse than vinyl, but no one who really cares about sound quality should be listening to either compressed MP3 or vinyl. Vinyl necessarily has extreme equalization in order to achieve any bass response, necessarily lacks sufficient channel separation, and degrades every time the record is played. </rant> THIS I agree with wholeheartedly.

    This major release introduces MQTT, another piece of the Industry 4.0 puzzle. MQTT is a machine-to-machine connectivity protocol that runs over TCP/IP. MQTT joins the UniStream range of communication channels and protocols that supply the connectivity required by Industry 4.0 including SQL, built-in webserver that enables the controller to be accessed via any browser, and more. This release also supports new UniStream 5” models US5-Bx-R38 + US5-Bx-T42, offering new, built-in I/O configurations. Other important features in this release: HID Device support for devices such as scanners PostgreSQL support, in addition to SQL Server and MySQL UniApps localization for Korean & Italian, plus a new Korean virtual keyboard Read the version changes for more features at: https://unitronicsplc.com/software-unilogic-for-programmable-controllers/

    I've had a lot of local requests for help on getting email working. There are a lot of pieces needed to make it work right and it has to be done in the right order. A PLC was never invented to send emails, and the fact the Unitronics can do this is a pretty awesome feature. I'm posting a sample program we wrote to hopefully show everything needed and some tricks to make it cool. Joe T. Sample Email Program V570 5-6-15.vlp

    What is the answer to this math problem: 7-1x0+3/3=? If you understand the PEMDAS rule you will get the correct answer of 8. However, if you just run the operations from left to right, you'll get 1. Every ladder rung in your program must be compiled to machine language before the PLC can execute the code. Do you know all the rules the compiler will use when you have a very large net? I certainly don't. Remember, like all computers, the PLC can only do one thing at a time and a large net can provide ambiguity (to humans) so the result can sometimes be unpredictable. To avoid this potential problem, always make your nets reasonably simple and break them into functional parts. It's also easier to troubleshoot and for another programmer to understand what you're doing.

    Ohh no, the old usb issues! 1 Perhaps Win 7 is now doing the W10 trick of updating drivers to whatever Msoft deems best, regardless of what the user wants/knows. I'm still on 7 and haven't encountered this yet, but I very carefully look at every update that is offered and find what it is doing. The immediate suggestion is if you have System Restore on, you should roll back to before the updates and see what happens. 2 I have had instances where a usb cable has suddenly broken a line internally. I'm assuming you have tried another known good cable in your attempts? In my instances the error messages you're getting were similar..."unknown but I know something has been plugged in." Murphy's law says that this failure is going to happen just after an update that will appear to be the culprit! 3 Have a good read of this entire discussion: In particular note the program I recommend: http://www.pro-it-education.de/software/deviceremover/ Edit: I have discovered this link doesn't work anymore. Can now be found here: http://www.softpedia.com/get/System/System-Miscellaneous/Device-Remover.shtml I have found it incredibly useful for removing dud drivers Windows squirrels away. If you haven't had luck doing 1 & 2, try getting rid of everything using it and start again from known good drivers. ONLY install them. 4 I am finding more and more devices that used to be serial connections, but are now usb in the same looking body. But lo and behold they have just added a prolific/fake chip onto the pcb so that it "looks" like the unit is usb to the user. It is essentially still serial and the onboard chip lets them get into it if they don't have serial connections available, like modern stuff infuriatingly doesn't. I have been exceptionally careful about what I allow to happen during the first insertion of any device that likely falls into this description. It is a minefield. Tread carefully! cheers, Aus

    This problem dates back to when the USB to serial adapters were first introduced. It is not a Unitronics-only problem, it's a Windows thing. I have experienced multiple instances of the same driver trying to access the same COM port when it comes to the USB interface. It is a royal pain in the butt and you have to rip them all out and start with a clean slate. The problem is you can't see them all, even if you check "show non-present devices" in the Device manager. There is an environment variable you have to set to truly "Display All Non-Present Devices". This article describes the process to get all your defined COM ports to light up- https://technet.microsoft.com/en-us/library/ff184583.aspx You probably have a bunch of stuff defined that you didn't even know about. Uninstall all the COM ports. Then plug your PLC in and see what happens. Joe T.

    I would like to start with many compliments on the Unistream Product. Yes it is a huge cost savings from other comparable products out there, but the horsepower really comes to light when using the data tables, FTP interface and the USB DOK tools. Not only can you accomplish a lot of traditional tasks with these units, but you can work with data and share this data so easily. Thanks. There are (2) enhancements that I think go together that would put the icing on the cake. 1st, we need at least (2) dimensional arrays. You have sort functions for arrays, but with only a single dimension, I typically need to have another field that is associated with the sort field. 2nd, having a sort function for data tables would be so powerful. Being able to run a Min/Max sort on a column so the data table can be organized based on a column sort would provide more capabilities with data tables. As a note, I cleaned up the Num to String UDFB to eliminate the space allocated for the +/- sign when neither are used, finished the 0 fill feature and increased the number of digits so double integers can be converted. Again, nice product and this only looks like the beginning.

    So I am sure that some of you may know factoid 2 already but I decided I would share the benefit of lots of testing with everyone. In our products we use the V570, V350 and the JAZZ units to talk to variable speed drives on a regular basis. Most drives come standard with 485 Modbus as the only communications type unless you spend extra money getting optional com cards for the VFD. Two factoids relative to noise. There was a conversation that happened accidentally in the "I have a new project" topic where someone said that Unitronics was very susceptible to noise. Well VFDs make a large amount of noise and it is not always radio noise. A fair amount of the time the noise is actually contained on the local earth to where if you ground the shield of shielded cable you make your noise problem much much worse than in you do not ground your shield. The old conversation about sometimes you have to ground a shield on one end or the other or not at all must be practiced regularly. Factoid 1: I generally would not recommend one brand of product over another but 20 years of use on pressure transducers have shown conclusively that there are definite brands of transducers that work dramatically better than others in noisy conditions. If the noise is radio noise pretty much every transducer is as good as any other. If the noise is carried on the local earth ground of the machinery then really bad things happen on every brand of transducer I have ever used (list to follow) except 1. We have used: Ashcroft Murphy Pepperl & Fuchs GEM WIKA AST Dwyer (all private labeled so there is one that works) and in 100% of the cases when there is a site that has noise infecting the ground because of VFD usage there is a horrible amount of noise created (it has nothing to do with Unitronics) and there is only one cure (separate the sensor from the metal pipe is it screwed into to isolate the sensor from the grounded pipe. If you ever have a site that has what appears to have an incurable noise issue and a VFD is involved unground the sensor and see what happens (pressure sensor just unscrew it and leave is unconnected to anything metal and if your noise issue goes away your grounded piece of equipment is causing your noise issue. So what is the one sensor that seems to be impervious to noise on the grounded pipe? It is specific to exactly one model and one product type only. The SETRA 209 series pressure sensor works perfectly where nothing else will (without lots of noise smoothing). AST is second best (but not as good as the 209 series SETRA) and everything else is just bad. Unfortunately, the 209 series is not NEMA 4 rated and is only suitable to outdoor use with the help of a cover to make a 3R cover. No other model of SETRA transducer works like the 209. Just as a note (if you are not needing Class 1 Division 2) there are companies that make electrically isolated pipe union fittings (for cathodic protection) and we have used these from time to time to help customers through ground noise problems. Factoid 2: It is in the Unitronics documentation but who reads everything (or remembers it over enough time). When connecting to RS485 it is not just important but absolutely imperative that you do not connect wires to pins 2,3,4 and 5. Even if the opposite end is connected to nothing at all (except 1 and 6). What testing has shown is that if any of the other 4 wires touch each other (because you cut them short) they will make an otherwise quite communication line unbelievably noisy. Also even if the ends are not touching the wires themselves act as little antennas and noise becomes worse. How do we know and not guess at this? Because sometimes we try to do what is right and it ends up being horribly wrong. One of our techs went out an sourced a high speed modem cable (shielded with shield all the way up to a metal sheath on the plug). It was not an inexpensive cable and sounded like a really good choice. We were buying 15 foot cables and then cutting this in half to make 2 cables (other devices have screw terminals for their connections and not an RJ12 (RJ12 for RS485 to get all 6 connections) so we would cut away all cables except the two making connection to 1 and 6 at the Unitronics port. We had 70 or so with these cables out and a high percentage of the build had special drain wire considerations that had to be made to make the communication work ok. New project with a different brand of VFD has come along and we build our first three units and zero of them would communicate over 485 communication connection. (we tested everything before build and it worked) WHY? The cable we were using had 4 sets of twisted pairs inside the shield (so two wires were not connected on either end). Testing on a V350 showed that as long as we had a computer connected to port 1 communication between the PLC and the VFD was fast and excellent TX/RX accuracy, but as soon as we disconnect the computer from port 1 communications would fail to a rate of about 75% packet loss (at slowest communication speeds). We tried different grounding of the shield to no effect, we replaced cables (didn't expect that one to work) to no effect, we took the test VFD from our desk and replaced that VFD with one in the constructed panels (no effect), so then just because there was nothing else to try we took one of the connectors that comes in the box for the V100-17-RS4X Modbus adder card and just twisted that to a standard 3 wire Beldon (really poor connection) and communication success went back up to about 99%. So we soldered 3 of the connectors from the V100-17-RS4X and shrink wrapped it all so that we could ship the 3 panels to their end customers. Then began the process of figuring out the whys and wherefores as to what the heck was going on. Taking new (expensive shielded) cable we stripped multiples back all the way to the metal cased plug and found that the manufacturer had done a good job on construction. We removed just the two wires that were not connected to anything on either end and found that removal of the two unconnected wires help com success rise to the 60% level. Then made sure that no wires were touching out of the remaining 4 unconnected wires and coms rose to a 90% success rate. Then we cut the 4 remaining wires to be about 1 inch long and made sure they did not touch anything and coms rose to about 96%. Then made our own cable with an RJ12 connector to have only 2 (totally unshielded wires with low twists per foot) wires and comes were great. So now we will be buying specialty cables that have only the two required conductors inside them. Thank for reading and I hope our pain can save you some. Keith

    Hello, I currenlty busy with a project Unistream 7" + 2x 8DI/DO and a EX-RC1 + 3xPT4x, 2x4AI2AO + 2xAO6. Followed the instruction on the webinar. What took me some time was that you have to upload a ladder programm with Visilogic to the EX-RC1. They don't show it in the webinar - because standard the EX-RC1 is pre loaded with a program - which has an auto configuration for digital inut and output. But when you want to use it for analogue input/output you should change it - by uploading the program in Visilogic withe the serial (9 pins) cable and RJ11 connector. When you follow the webinar - the example is shown for maximum of 16MI. In my case it exceeds 16MI - so I had to change the program. After a lot of 'trial and error' I came to a simple sollution by stripping most of rungs out - and only used the minimum of code. To get the second set of 16MI - you have to change the start adresse by adding 16 (so 1016=start adres first vector, 1032=start adres second vector), and bassicly follow the instruction in the webinar. When the first vector is sent/receive through the canbus MB0 and MB1 blocks the sent/receive off the second vector. I attached the visilogic file - feel free to use it - or comment on it - I'm not an experienced programmer so constructive criticism is welcome. EX-RC1 - example more than 16MI.vlp

    Hello Active Just did a simple test with Kepserver and selected the ”Modbus tcp/ip driver” Channel properties=>Ethernet settings selected port 502 and ip protocol tcp/ip. Added a device and named it device1 and for the model selected “modbus”. ID <>20 The V570 has this ip address and 20 is the slave number in my test situation. In the V570 socket init in my case socket 3 port number 502 and server(slave) followed by A Modbus ipconfig,selected in this function block socket 3 and gave it network id 20,time out 100 and retries 3 and assigned a function in progress mb. The indexes with slaves can be deleted using the clear link button. The next network has to have a “Modbus ip scanex” block and for the name in this block select the name of the Modbus ip config block. TCP card init was already done somewhere else in the program but you could follow the example explained in the visilogic helpfile and it’s called “configuring a modbus slave device”. In this example for the gateway you have to choose the ip address of the master unitronics plc but this is only needed I think if communication is between Unitronics plcs so leave the TCP settings in this block as they should be four your local network. For addresses see the example in the visilogic helpfile called “slave addressing” under Modbus ip. To test this all I started kepware opc quick client and added here an item “channel1.device1.40032” and here I can see the actual value from MI31 So kepware acts as a Modbus client and the V570 as a Modbus slave device in this situation. Did no projects with kepware and Unitronics but in our plant we have some Unitronics plc,s besides TI(CTI) PLC,s connected to Control Maestro(Wizcon) scada using Kepserver so this is why I could quickly made a simple test. Hope it will help you Regards Henny

    A shepherd was herding his flock in a remote pasture when suddenly a brand-new BMW advanced out of the dust cloud towards him. The driver, a young man in a Broni suit, Gucci shoes, Ray Ban sunglasses and YSL tie, leaned out the window and asked the shepherd... "If I tell you exactly how many sheep you have in your flock, will you give me one?" The shepherd looked at the man, then looked at his peacefully grazing flock and calmly answered "sure". The man parked his car, whipped out his IBM ThinkPad and connected it to a cell phone, then he surfed to a NASA page on the internet where he called up a GPS satellite navigation system, scanned the area, and then opened up a database and an Excel spreadsheet with complex formulas. He sent an email on his Blackberry and, after a few minutes, received a response. Finally, he prints out a 130-page report on his miniaturized printer then turns to the shepherd and says, "You have exactly 1586 sheep. "That is correct; take one of the sheep." said the shepherd. He watches the young man select one of the animals and bundle it into his car. Then the shepherd says: "If I can tell you exactly what your business is, will you give me back my animal?", "OK, why not." answered the young man. "Clearly, you are a consultant." said the shepherd. "That's correct." says the man, "but how did you guess that?" "No guessing required." answers the shepherd. "You turned up here although nobody called you. You want to get paid for an answer I already knew, to a question I never asked, and you know very little about my business...... Now give me back my dog."

    Yes. You'll have to send them a text from within your ladder logic. Vision series Email blocks are not capable of using an email server that uses SSL, so you'll need to set up an account with a non-secure email server. The only public one we know of that can still do this is SMTP2GO. Look at the Example project for Email on how to set this up. Check out this post- Joe T.

    This is exactly what I had to do with Visilogic in an application that had multiple users with a couple of different access levels. As you've figured out, it wasn't the easiest thing in the world. UniStream addresses this with User Access Control that has 16 levels, 16 groups and 128 users. If this is really important to your project you may need to switch platforms. If you haven't already downloaded UniLogic I'd recommend doing so and having a look. Joe T.

    Hi Joe, I've worked with modems and communications on Unitronics for many years. They do certain things extremely well and we have seen many successful applications. More detailed comments and advice are below: 1. Ability to log in to the PLC Web Server - This is the most difficult of your 3 things to achieve over GPRS. You need at least a public, dynamic IP address. Once the GPRS connection is active, you then need a way to find the current IP address of the modem. One option is to get the PLC to send its IP address to you in an email once it has connected to the network. Note that this is not secure, anyone who figures out the IP address and what device is at the oter end can start to try and access it. 2. Ability to send a weekly csv. file via email - this works reasonably well, the nice thing about sending emails is that the IP address does not need to be public. However with the Vision family, you need an email server that can accept unencrypted connections. 3. Ability to send text msg for alarms - by far the easiest thing to do with the EHS6T and a V350. I would only recommend this modem to do SMS and nothing else. Trying to mix GPRS and text messaging is not simple, as the PLC to Modem communications has to be reconfigured for each mode (SMS or GPRS). Overall I found GPRS to be a fragile and difficult method of setting up a data link. If you want to use the web server, I would recommend switching to an Ethernet modem, which would also require the V100-17-ET2 card for the PLC. With ethernet you can do things like Dynamic DNS or VPN as a way to maintain a connection to the unit's IP address. However when switching to Ethernet, there is no easy way to keep using the SMS feature at the same time. The simplest workaround for that is to send all alarms by email, as most people now receive emails on their phones. SMS is beleived to be "reliable" but the SMS standard allows 24 hours delay in delivering the message (I heard a rumour that has been increased to 48 hours). In short, from my experience, it's not possible to do all 3 tasks that you have described with a single device/single connection, using just the standard built-in features of Unitronics. If anyone can improve on my advice, I'm happy to be corrected.

    Hi; Been there , done that. This is a Windows related issue. There is an install shield file that has information in it causing the problem, and has to be moved or deleted. Here is a solution: CAUTION : I Take NO Responsibility for anything that happens ( good or bad)!!!!! Local Administrator privileges may be necessary. KNOW what you are doing! Open C:\Program Files (x86)\InstallShield Installation Information There are a few or many very oddly named folders e.g. {12AB95C7-C72D-4CF5-9B6D-7452DF048C56} Starting at the top, click on the folder to open it: Each folder has a group of files. Look for the file : Setup.ini Double click to open the file or open the file in Notepad ( Notepad ONLY, this is a simple Text File) Top Line [Startup] 2nd line AppName= If the App name is NOT VisiLogic, close Notepad ( DO NOT do a Save or Save As) Move on the next folder If the Appname= is VisiLogic, Close Notepad Back out of that folder, Cut the Folder and Paste it into the Downloads Folder -- Just a safe place to put it for now. Also Rename the Folder and ADD - VisiLogic Restart the VisiLogic Installation, and ( fingers crossed ) it should go smoothly. You can also run a registry cleanup program later to locate and delete unused registry entries. Dant

    I'm converting a V700 program to UniStream and came across a PWM SCAN block for heater SSR control. I searched the Toolbox and the Help and came to learn that the PWM block is not a standard block in UniLogicLand. Then I went looking on the UniStream software and hardware forums - nothing there. After about an hour of getting frustrated I looked through the UniLogic examples. Which I don't normally do - I'm an experienced programmer, by cracky!😫 Anyway, lo and behold, there was a PWM example. Turns out the PWM block has been morphed to a UDFB, which was actually pretty easy to implement after I figured out one of the input tags is a TIMER data type. Fortunately one of the Creators thought of this. So I'm posting the UDFB for everyone's reference. Joe T. PWM.ulle

    For anyone producing their own electrical/control drawings you may have noticed the downloadable blocks in the technical library. Personally I have only ever found these useful for overall dimensions or to show the display on a general arrangement drawing. It's a shame we don't have anything showing the actual connections in .dwg (a bit like the images in the install guide). Anyway I will post here something which has helped me provide clients with a reference for connections. These are blocks and in reality the PLC connections will have interconnecting wires and all the usual stuff you would expect. I have lost count of the amount of times I have encountered the terminal number vs input/output number confusion!! Feel free to offer any thoughts. V350_Blocks.pdf V350_Blocks.dwg

    You've got your work cut out for you. Usually once a customer has AB tattooed on their butt you need hydraulic machinery to get it off. The PLC 5 family has been completely obsoleted by AB and is pretty much only available on eBay and through surplus suppliers. The official AB solution is to convert them to the ControlLogix platform, which carries a hefty ($10K) price tag. Which blows because the PLC 5's actually still work great. PLC 5 Ethernet is the old AB Ethernet protocol, which is not the same as Modbus TCP. It talks to SLC 5/05's and RSLinx AB-ETH drivers. Channel 0 on some PLC 5s can be configured for RS232 DF1 protocol. Unitronics Vision series can be a DF1 master in a convoluted way, but it does work. UniStream does Ethernet I/P, which is not compatible with a PLC 5. If all you've got is Data Highway+ then you'll need a protocol adapter. I've got such an animal that converts DH+ to Modbus TCP - message me if you're interested. Which PLC 5 are you dealing with? Or is it a bunch of different types? Joe T.

    In a future release of Visilogic, it would be great if you could have the option to make the properties window permanently visible, perhaps on the right side. I use Visilogic alot, and this would save so much time from right clicking on an object (objects that bring up a variable window instead of properties window when double-clicking) and clicking properties. Not a big deal with small projects, but tedious for big projects with 100+ objects across multiple screens. If there's already a way to do this, someone let me know. Thanks.

    Just use a self-resetting delay timer, as follows: T0 T0 -|/|------( )- ------------------------ T0 -|P|-, in place of SB13

    There is an example for PID loop in U90 ladder called "PID with motorized valve". You should check it out. Idea is to have a register that will contain virtual "position" of the valve expressed in 1/10 of a second (you need to know time it takes for valve to fully open from closed position, this will be PID max output). You will then compare this value with the PID output, if it is smaller than PID you open the valve, if it's larger you close it. You should have a small deadband. If output for opening the valve is active you increment virtual position register every 10ms (SB7). If output for closing is active you decrement it. I used this before with Vison and Jazz controllers and it works well.

    If you convert from BMP to PNG then no alfa channel is define. So first you need to use the command color to alfa. I recommend the software GIMP (it´s a free software and very powerful). You can find a lot of YouTube tutorial about adding transparency to a PNG using GIMP. If you need more help please send me an email to : ober.yela@Imapsa.com I can send the links.

    Saragani is one of the system architects--his advice is worth talking :-)

    Hi Flex: I understand you are going to send MIs between 2 V570 (or Unitronics PLC´s). You can send the 160 registers in one action (but only if the 2 PLC´S are Unitronics). You need to use the Read/Write Mixed Data (you can send a max of 240 MI´s) in a single action command. I only use the Read/Write Mixed Data if working with Unitronics PLC´s. If you need to communicate with 3rd party then use the standard commands.

    The Creators are not going to give up the .vlx file format. The problem of multiple copies of nearly identical code is addressed in the new UniStream product with user-defined function blocks. If it makes you feel any better, I've done the copy-and-hope-you-get-all-the-replacements-right dance more than once and you just have to plow through it. If you haven't looked into the Search and Replace feature of Visilogic you need to. It can work on the subroutine level and does make things easier. Joe T.
