  2. You do know you can set a data table column as a string type, don't you? Then it's just a matter of specifying MI 350 in your Data Table write row block. The block will take care of the vector length. I've done a very similar application, but I put the employee IDs in one table and then had them log in at the beginning of the shift and searching the table for their user level. I copied that to a buffer and stamped that ID along with other pertinent data on the into production table. Upload your program so we can have a look, or PM me if you don't want to share. Joe T.

  3. Hi All, New firmware has solved this one.. Ghosts in the machine unfortunately. Looking through the release notes there isn't anything that specifically addresses the issue. Regards, Louis.

  4. As i see on cable pic. - this sensor is two-wire. RED wire connect to +24V (+V) of power supply. Blue/green wire to ANALOG input (4..20mA). Black wire to GROUND (Earth). -24VDC (0V) of power supply connect to ACM.

  6. OK, please note that the fix was applied to buttons and text elements only. In the future it will also be applied on image elements, tanks, meters, and gauges.

  8. This is where I found out there's literally no end to how much I/Os you can cram into a V570. The year is 2011, my first medium-scale PLC project. It was an animal food production plant. There was about 200 I/O points at first, and later the system grew to about 250. Also numerous weighing scales and temperature measurements. When I found out that there would be no way to put any more than about 100 I/O points via Unitronics modules, I had to resort to Turck's CANopen I/O modules. These pack a respectable number of terminal blocks per square inch of panel space. It all worked flawlessly,

  11. Back in 2011 I've come to the conclusion that V570's hardware is a beast, and that no amount of ladder code would be able to fill it completely. So in 2014 I did a project with 3 V130, which are supposed to have the same CPU and memory power as V570, only in a smaller, cheaper package. This is a small automation project involving few mixers and some material flow management. We have 3 PLCs, talking to each other via Ethernet, and a supervisory computer. Everyone loves to have a shiny 24" monitor, but paying more than $500 for a Scada package couldn't fit the budget, so Z-View SCADA was th

  12. I recommend getting directly with a system integrator or your distributor for help with this, as it's more complex than the usual situation. I suspect the recommendation will be to use Canbus for remote I/Os combined with 5 IO-D16A3-RO16 modules, 4 IO-AI8 analog input modules, and 4 IO-AO6X analog output modules, though that will leave you no spare digital inputs. It might be better to add a Snap-In module such as the V200-18-E6B and reduce the IO-D16A3-RO16 by 1. I mostly counted this up in my head and I'm shooting from the hip, so please don't make any I/O decisions without consulting a syst

  13. Maybe best solution is to use Ehternet add-on card V200-18-ET2 and URB IO Please see new Visilogic 91 version. https://www.unitronicsplc.com/Download/SoftwareVersions/Visilogic/VisiLogic_9.8.91_Version_changes.pdf About URB https://www.pl-systems.fr/wa_files/unistream_remote_i_o_user_manual.pdf

  14. Sure you did. If your scaling is 0-5bar and you put 0-50 in your linearization block, then your resulting value after linearization will be in increments of 0.1bar.

  15. Both "Store in Array" and "Load from Array" do work in my case with bit array. Does it give some sort of errors ?

  16. I'll explain the problem I had, maybe it helps somebody. I have several controllers that need to have synchronized RTC, and there was a problem that time update didn't work properly. After some troubleshooting I found that "Status" variables need to be defined in order for function blocks to work. This does not work (usually): This does work: Both cases compile the same without error or warning. UniLogic version 1.28.34 PLC USP-070-B08

  17. Hey @balazs.tarro-HUN Last week I had the same issue with the trends and another one sending mails. I contact the support to have some informations about it. Figured out that they didn't knew why I the sending mail status was always remaining to 0. But then they suggested me to force the update of the PLC. You can force an update going to unistream management in Unilogic and by clicking on remote update. I'm not 100% sure that it will resolve your problem, but it resolved both of mine.

  18. That's how I read it. Then for grins I loaded one up with (6) 16 point analog inputs and (6) 16 point analog outputs. That's 192 bytes each way: It compiled with no errors. Try playing with different configurations on your own. You're not going to break the software, and it will certainly tell you when you've screwed up. Just like people. 😁 Joe T.

  19. I had a customer call recently trying to install Visilogic and was greeted with a "Catastrophic Failure" dialog box. Usually, a Catastrophic Failure means parts are flying out of the machine, something has caught fire, or your transmission in your car decides to delete the "mobile" part of your automobile. Windows 10 has brought us the joy of everything having to be done as Administrator. I've updated the Visilogic Reinstall instructions to include this necessary step. This is not built into the Visilogic install package, and I have it on good authority that this is difficult to do wi

  20. Anyone who has ever used a slide rule understands all of this intuitively, but I don't think anyone younger than 50 (60?) ever has. With a slide rule, you do all computations without regard to decimal location and just keep track of it mentally. At the end you add up the decimal places in your head and write it down accordingly. That said, I certainly wouldn't trade my calculator for a slide rule today.

  22. 3 years ago I knew nothing about PLC's. Because of people like @Ausman, @Flex727, @Joe Tauser and others on this forum, we converted 8 machines from old relay logic to PLC's with automation, made 2 pieces of complex laboratory test equipment for the lab, and entire tank farm controls that include, levels, filling, heating/cooling, mixing etc. I could have never done it with their help. I don't know if they're paid or not, but I will tell you they are priceless. I hope that @Cara Bereck Levy will show this to the powers at be so they understand the caliber of people they have in this foru

  23. Everyone in the process of building a program in the Visilogic comes to their own style of writing. Therefore, we can come to the same action in our programs in completely different ways. In most cases, I have to test the program without having the whole system at hand. Therefore, for almost all types of panels, I wrote "my standard" routines for polling inputs and output control. This led to the idea that the activation of the output should be only in one place in the program - in this case, the subroutine OUTPUTS. Input polling is similar in another subroutine INPUTS. Values

  24. This is from new Visilogic CANopren+ Servo help But it is about older version of Visilogic It is present in 9.8.65 help also. Maybe something no documented changes appear in new visilogic. But it is not present in help Please try to check code in SDW34 ----CANopen: Abort Code in SDO Abort. Check Help file for codes SDW36 ----CANopen: Bus OFF error. Check Help file for codes

  25. A Samba really doesn't have the horsepower to push a servo system. I would use a V700. Don't shoot yourself in the foot based on price. Other than that all you need to do to drive servos is add a CANbus card and download Visilogic 9.8.90. You can add an -EX3 snap IO card for up to four thermocouples on the V700. Joe T.

  26. Input Response Time = 10ms typical, when used as normal digital inputs. In your setup 1 turn Time1(sec) = 1/ Freq (Hz) = 1/40 = 0.025sec=25ms 1 turn Time2(sec)=1/100(Hz)=0.01sec=10ms Your sensor "see" metal only for short time during the 1 turn. If you increase the frequency, the input does not have time to "see" a number of pulses - the sample frequency drops. For test fan rotation you can use timer started by sysytem RUN bit. Sensor from your setup must reset timer by --|P|-- . If no timer reset present for preset time - you set alarm by time

  27. 48 analog inputs per EX-A2X or EX-RC1, 6 IO-AI8. It is because data bus capacity, not PLC memory, if I remember well (from support answer I got time ago).

  28. I use UDP instead of TCP set as protocol in a single socket init. With UDP there is not need of connect/disconnect everytime I change to the next slave query. Query first slave, wait for its response, process data, wait a small time, query second slave and so on.

OK, some things that I have ran into, oh the fun of phantom currents! - Are you using the correct type of extension wire? - Do you have it in a tray with motor wires? -If so, is it separated by a metal divider? -Did you coil up excess wire anywhere near a motor wire in the tray? -Do you have it going in a standard din connector? - Did you have an exorcism to drive away spirits?

  32. Permanently run remote access or remote operator on the PC and tuck it away in a little used corner of the desktop? Or....have a look at UniDDE, or perhaps UniOPC https://unitronicsplc.com/Download/SoftwareUtilities/UniDDESetup_1_3_6.exe DDE will likely give you the basics of what you want, but you might need a little script running to cycle things periodically to fully achieve your needs. So you'd have a little excel window running and updating with just the info you want visible. cheers, Aus

  33. Dustin sent me his application privately. The problem was the images he was using had different outlines, so using "Transparent Background" left relics of the previous image visible. Not using the transparent background didn't look good, either, as the resulting animation looked weird and blocky. The solution was to use both "Transparent Background" (which applies to the image) AND "Draw on Back Color" The color used for Back Color can be selected, so I chose the color that most closely matched the pipe he was overlapping with the animation. It wasn't quite as good as a Bugs

  34. I had a similar issue on the Samba PLC. For me, the solution was to raise SB 31 (Refresh current LCD screen display variables) whenever the image has changed. Maybe that will work on the V570 as well.

  35. Just for interest's sake some thoughts on relays. I have copied in here some specs for a common relay Unitronics use. Mechanical 50,000,000 operations min. (at 18,000 operations/hr) Electrical 100,000 operation min. (at 1,800 operations/hr under rated load) Note the large difference between what the relay mechanicals are capable of vs what the electrical contacts are capable of. MTBF is something that designers often (inadvertently) overlook. I find it amazing that a relay maker will say their unit is OK to do "1800 operations/hr under rated load", when clearly if you run th

  37. At the end of program (at the end of every scan) copy those registers into some other free DWs. Then at startup copy them back, via SB2 contact. I think there should be a complete example of this method somewhere in this forum, I've seen this topic before.

  38. OK Tyler, Before doing anything else, just as a precaution do a copy of your entire my documents folder by accessing it via C/Users etc. I think your best option at present is to see if you have a System Restore point still in existence before you did anything Unitronics. If you do, set that underway and see how well it restores things. If you don't have a restore point back far enough, with Visilogic 9.8.65 installed, use Revo Uninstaller portable ( https://www.revouninstaller.com/download-free-portable.php ) and do a thorough uninstall, as deep as the program lets you run i
