  1. Hey guys, I have a UniStream 7" PLC connected with EX-RC1 expansion module via CANBUS. The CANBUS is connected according to the info in the datasheet with 120 ohm resistors and everything. The complete configuration that the PLC communicates with from left to right is as follows: EX-RC1, 3 x IO_D16A3_RO16, 2 x IO_ATC8/AI8, IO_D16_A3_RO16. The PLC and the EX-RC1 is grounded and connected as it should. EX-RC1 is programmed (initialized UniCAN) and the LEDS are all working propperly (PWR ON, I/O COMM ON, BUS COMM ON). Accordingly I am able to read/write all the inputs/outputs. So, the whole system and configuration is working propperly. A few (2-3) months later EX-RC1 dies (only PWR LED is ON). I can't read/write any of the inputs/outputs and the IO modules I mentioned earlier all blink ( no communication established). I tried restarting the whole configuration by turning the power supply OFF and then ON. Tried to reprogram the EX-RC1 but when the download starts it shows an error that the device is not available (not sure what the error said). So I thought to myself what the heck. It died, it happens and I replaced the module with a brand new one and installed a separate power supply used only for the EX-RC1. The whole configuration started working again, the comm was up and the PLC software was fully functional (able to read/write and execute). However a few months later ... surprise ... EX-RC1 dies again. The exact same circumstances. Is this a compatibility issue or? Thanks in advance for your help. Any suggestions/ideas are really appreciated.
  2. I need to interface a Unistream with an Omron PLC. Specifically, the OMRON SYSMAC CJ2M CPU31. Omron requires an EDS file for all Ethernet/IP connections and a generic EDS file we found does not seem to work. The Unistream is configured as an adapter and the Omron is configured as the scanner. During testing, I did attempt to switch roles and have the Unistream as the Scanner and the Omron as the adapter, but neither configuration seemed to work. The error message in the Omron indicates a byte count issue; however, with the assistance of an Omron integrator, we confirmed that the number of bytes in and out of the Omron is correct.
  3. I have problem with output. Life expectancy for UID - 0016R is 100k. How many times can I switch the relay output in this unit? Thanks Martin UID 0016R
  4. Hey all, The PLC I'm using is an Unistream 7". I'm writing an application where the PLC needs to communicate with a server through a TCP connection. Communication is established through a Restfull API; - PLC asks the server when needed for a list of all the configured items on the server. This list is JSON-formatted, will be parsed by the PLC and then loaded into a DTI for further use.. - PLC sends updates to server when an item has changed state. - Server sends commands to the PLC when an item needs to change state. Setting up the TCP client Rx was a breeze! Communicating with the server works like a charm if the received messages are smaller than the receiving buffertag of the TCP client Rx FB! (e.g. commands from server to PLC) If larger then the buffertag, the message will be truncated. (e.g. List of items send by server to PLC) => According the help-file: due to insufficient buffer size (user buffer) I noticed that a buffertag can be defined as a maximum of around 1600 bytes. I was wondering why this limit? And then again, if I could enlarge the buffer to say 3500 bytes and my list grows eventually beyond this limit.. So.. How do I receive a message that's larger then my predefined receivebuffer? What am I missing? Tnx in advance, SRO
  5. Hi, Any alternative to the vision series essential app "SD Card Explorer"? This PC application allow explore and download files stored on the SD card from remote, and I cant figure out how Unistream SD Card filed can be approached remotely. I was tinkling of sending files to FTP server, but how can I browse SD card from Unistream panel / (VNC) and select a file to send on FTP server? it seems that HMI element "Sd Browser" can only be use to transfer files to a local DOK. I believe that If it had the option of coping a selected file name to global tag (string) then it could be used with "FTP Send" function. For now the only solution I found is to use pen and paper to copy a file name from the list, and retyping file name somewhere else on the HMI, but there must be a better way... Thanks in advance to the appliers. Ofer
  6. Hello When I convert an data sampler file (.uspm)to Excel it contains a column called "triggered" that is not the name of a variable I am logging. The value called "triggered" seems to react fast changes in logged value (se after time 20:56:27) and be more correct than the actual value(s)saved as logged (ATinRaw, and TTinRaw). Is this because the trend tool contains a built in filter? Is there any way to turn this filter off?

  8. Hi all, Anyway to convert between string types? I would like to store an ASCII string to Data Sampler/User Comment 1 string that is build as UTF-32. while compiling the app get an error: Data type mismatch. Thanks in advanced, Ofer
  9. I have an application where the PV moves very fast. When a known disturbance or an anticipated disturbance occurs, I would like to pause the PID loop calculation and lock by CV where it is. I see that Unilogic has a Pause I&D calculation that seems to be the feature to use in this sort of situation but what I am wondering is whether or not I would have better results if I simply de-energized the PID Run Block and then re-energized it when the process is expected to be stable again. In other words, what is the difference in the calculation between simply removing the PID Run command and Pausing the I&D calculation?
  10. Hello. Does anybody have some tips on how to enter exponential numbers into HMI "Numeric Box"? Example: 1.347E-19
  11. Dear all, I am newbie to Unistream and Unilogic. I need help on how to change (vice versa) Read Only attributes of Numeric Box. Eg: Prevent the numeric box from access when "Auto Tuning" is enable (let's say the PID settings). Hopefully somebody could give an advise. Thanks, Salimin
  12. Hi, I'm having a power related issue with my analog I/O, I'm trying to read the log from the PLC but when I uploaded it using "Unistream management -> Debug -> Upload Log" I got 4 files, 3 of them are .zip a(Unilog_Backup.zip, Unilog_fail.zip and Unilog_Tmp) and they are password protected, my project doesn't have any kind of password so it can't be a protection that I set before, is there an universal password for opening this zips?
  13. Greettings, I'm a Electrical Engineer from Venezuela currently developing an application using one of your PLC, a USP-156-B Unistream device,I was testing the behavior of the data table and data trend funtionalities and when booted to implement in my project, the PLC requested an SD card, I inserted an 8Gb Sandisk micro SDHC SD card and proceeded to manually reboot (turning the power down, and then back up). Now the PLC won't get past the black screen with the UniStream logo (I believe this is the boot up function) with or without the SD card. Is there a way to upload the firmware? or how do I solve this? I can't get into Uniapps.
  14. Hi, is there a way that I can Force analog I/O, especifically the Analog In value?, I'm trying to simulate my process for debugging and I've already forced the digital inputs, but I can't seem to force an analog In, In my process I need to check the level of 4 tanks and a weight scale, I get this information through 4 LT and a Weight transmitter installed in the plant but in my office I only Have one process calibrator, so it would be really helpfull if there is a way that I can Force this value.
  15. Hi all, Question: Is it possible to turn the backlight completely OFF in Unilogic by ladder?If I try to control the brightness by ladder; Actions - > "Change Brightness" and link a UINTThe help-file states: So this seems to be normal behavior. But if I use Uniapps -> Display & Audio; Sliding the brightness-slider to zero, does turn the display completely off!According to Version Changes, this is the case since Unilogic 1.8.51, Unistream OS 1.8.9, October 2014 Nevertheless, it would be ideal (for me and others too I think ) if we could get complete control over the backlight, from 0-100%, by ladder. In my application, the PLC will be present in a livingroom, controlling lights, heating, etc. Even at a percentage of 10%, the display is still quite lit up in a dark environment. To avoid being distracted by the lighted backlight watching tv eg.. and to save the precious backlight for prolonged life, I would like the possibility to completely turn of the backlight by ladder if the display hasn't been touched for a predefined time. => Is there a work-around without the need to open Uniapps or am I still missing something? PS. Updated the PLC and Unilogic software to latest releases, being OS 1.15.11 and V1.15.70 at the moment. Thanx in advance, Steven
  16. I have an application where I need to communicate with an ACTech VFD via Ethernet IP using a Unistream based controls system. I am using Output Assembly 100 and Input Assembly 101 to send and receive communications with the drive. At this time, communications seem to be working well with Word 0 of each Assembly but I cannot find out how to read the and write to Word 1, 2, and 3 of each assembly as individual words. When I set the Data Type to INT16, I get 16 Bits that I can read/write as Word 0 and when I change the data type to INT 32, I get 32 bits that I can read&write to but the 32 bits translate to Worda 0 and 1 of each assembly but I cannot fidn out how to see access Words 2 & 3 of each assembly. My questions are: 1. How do I access words 2 and 3 of each Assembly 2. How do I breakup words 0 & 1 which I can currently see as one 32 bit word into two 16 bit arrays so that it is seperated into Words 0 and 1? The manual for the ACTech communications module can be seen at the link below. I could not seem to upload the manual because the file size was too large. http://download.lenze.com/TD/COM__ESV__SMV%20EtherNet-IP%20module__v2-0__v2.0-B__EN.pdf
  17. Hi, I'm using Unistream for the first time and I want to know if it is possible to add up the values of an array? And is it also possible to perform a NOT operation on an Integer? Thanks in advance, Edwin
  18. Hello I'm already aware to the fact that transition contacts are not functioning inside UDFB, and there is an example application how to work it out, but what about SET RESET coils? It seems that SET and RESET coils are not latching as should be, if the bit is define as Local tag. Only as Global, Input or Output it works as normal. I tried to walk-around by building a simple holding circuit using simple coil, but this one also refuse to latch in ON state as well. Seems that there is no "memory" for local tags.,, a bit strange as it is very basic logic circuit.. The whole concept, as I understand, with the blessing USFB that one can repeat the same function many times in the project (working less-do more!) But if required to use many global tags (witch are not "duplicate" with the function) as momentary memory (Input and output tag will also be relate to global tags after all), then what is the point? or do I miss something? Any way to latch local bits ? What about numerical local tags, do they keep the value? Thsnks! Ofer
  19. Hi, I create an indexed data table, based on a struct previously defined. but now I want to change the table columns order or to insert a new column to the left. Every member added to the struct is placed at the end of the list and to the right column of the table. I found it possible to change columns order by dragging headers on the data table editor, but when exporting the data table to excel it is keeping the original column order as the original struct members order when created!! Also this order is shown at Uniapps data table viewer. This is not the necessarily the correct order required! Yes, I can delete and recreate the struct and the data table and rebuild them in the right order, bur is thee a beater way? like changing the struct members order? In addition I found it is possible to sort struct members by Name or by Type but not back to the natural order they created, and shown in the opened list in ladder elements . I guess a "Member #" column is missing for viewing, sorting and reordering, that can fix it all. Unilogic Version 1.14 Rev.62 Thanks in advance, Ofer
  20. Hi, I am trying to send email from Unistream PLC thru Gmail account. after sending the email via ladder, Email struct Fail bit is turning ON and getting -5 at the status register, which mean access denied when checking this account on Gmail, it revived a warning email subject: Sign-in attempt prevented "Someone just tried to sign in to your Google Account ***@gmail.com from an app that doesn't meet modern security standards." Please help thanks in advanced, Ofer
  21. Hi two questions and suggestions regarding Trend HMI element: 1) I would like the user to be able to change the X axis time frame, but the property window is not allowing to enter a Tag, but only a constant time frame value. any idea how to walk around this limitation? I found that y axis minimum and maximum values can be changed dynamically by defining a tag within Trend curve List configuration. why cant i do it for X axis too? I did consider using XY trend instead, but then the X variable cannot be displayed as time format. I would like to suggest that this parameter will linked to a global tag like timer preset. 2) Changing curves visibility ON and OFF is a common property mostly implemented by trend graphs viewer and I find it very essential, like if the user or the program wand to focus on a particular curve, or just hide irreverent curves from the display. any suggestion? I would warmly suggest to implement a binary Tag for "Is Viable" column, as for "Min Value" and "Max Value" column. is it possible? Thanks! Ofer Yishai
  22. Hello, I am new on unilogic and I have a quick question to you. Is it possible to change properties of HMI elements, like button's background fill color or size or other , in the ladder. Some function or bloc,or maybe with a script ?(script exist in Unilogic?) Thank you for your time. I hope my english is not too bad Your software is very friendly user and powerful. it pleasant to prog with
  23. Hi, I am trying to hookup some servos for valve control. The servos I have, require three pulse train parameters to output the control action: 600usec, 1500usec and 2400usec to give me -90degree 0 degrees and +90 degrees action respectively. Looking at the specs for a standard transistor output card (UID-0016T) these seem to able to switch at up to 80us which seems plenty fast enough. I thought I may be able to drive these directly by using a looped timer set at the respective times of 0.6ms, 1.5msec and 2.4ms, but it seems I cant get that resolution(<1ms) out of the timer? Do you know if there is another way to hook these servos up directly to an output card, or obtain timing output of 0.1msec resolution? I don’t think the Unistream system has a pulse train output card, and I am not sure if I could configure a high speed out card either? My fallback alternative is to use a serial controller for the servos and send out serial commands instead (but I don’t think this solution is as robust). Being new to PLC programming I just wanted to see if anyone had encountered controlling these servos before. Thanks Ian
  24. Hi I want to save my sampled data to a csv file on the SD and get the file from the excel via FTP. 1) by using the "Store DTI to File" function i got a file named "MyFile.csv.zip" is there a way to save a common "csv" file and not a zip file? 2) did anybody done that and have an example of importing a csv file via FTP using excel VBA/Macro? (Meanwhile, i managed to do it with the "shell" function, sending ftp commands.) thanks
  25. I am from Mexico, I hope you could understand what I wrote. I Have a PLC+HMI Unistream 7". I plug in the PLC to HMI and connect the HMI to Power supply, afterwards, screen "initializing" appears and remainds on that screen, kept for hours. I have checked my wirings, PLC and the HMI mutiple times and i sure it´s all in right. I can´t acces to UniApps and upgrade the firmware. The connection PC-PLC is succesful, but the PLC needs upgrade firmware. I hope you can help me. Thank you
