Hello, I'm wondering if my problem is a software one or hardware? And what kind of issues could be causing it in each case. The system is alright when at rest, but when put to work (triggered with input) it works fine for maybe 10-20 seconds and then I get a "CPU in stop mode" message on the screen" and few second later a message about CPU error. I've removed the CPU unit and put it back on, but with no luck. Does anyone have some hint for me? Thanks, Bjarni

Hello, I was interested in the "modbus set slave ID" block with its name, but I do not know how to work with it and what it does, I also wanted to understand - is it possible to change the slave ID in Unilogic?

Hi All, I have recently started a project controlling a servo motor for re-rolling labels. I have some mild PLC experience using Siemens but I have never set one up from scratch myself. Never used Unistream either. At this point in time I'm just focusing on sending a HSO to the servo using the Pulse Output on the URD-02PU. I have searched around but as these modules are so new I am having troubling finding information. https://support.unitronics.com/index.php?/selfhelp/view-article/Remote-IO-Pulse That is really all I can find. I'm unsure how I am to

Dears All, i am concatenating 4 String UTF-16 formated; between the strings I insert a ";" separator (also UTF-16 formated)...so...I am able to have the end buffer properly filled with th einformation...but I am not able to have a "new line" when I try again to append the buffer at the SD file. I tried to insert, at the end of the buffer, a lot of characters (u\2424; u\000D; u\000A...etc alone and conbined )...but nothing works...or better...with the file saved as TXT and with the u\000D in the "windows note pad" I see the right lines...but if I use "notepad ++" or i try read this as

Hi All, I just update one of my project, that is working perfectly, from version 1.26.90 to 1.29.111...and I saw that the ladder function Store DTI to File need more time referred at the previously version...to be clear I let 1 as F parameters (all file type)...with version 1.26.90 I think that the storage of the file needed much less of 1 seconds for each DTI....with version 1.29.111 I think 4-5 seconds are needed! I tried to clean the SD...then all the files are generated by the same version...but is the same. I also saw that some .sig file are added...but if the file name has

Im using a unistream 7 to communicate over serial with a pump. I am able to set settings over using the COM Tx and Message composer, however I am encountering issues with the COM Rx command. I can set rates and volumes without a problem, however I want to also grab the max rate and volume from the pump at the start of the app or when a user pushes a button. I should be able to send "read limit parameter", which then returns the max rate, min rate, max volume, min volume, The following is the return from putty. read limit parameter 29.12145 0.00010 29.31703 0.00269 > However it

Hello, i have a question regarding the file name in a store dti to file function. i need to create a new file every time i run the function which is set to happen every day at 6am. is there a character restriction in the target file name string? i would like to utilize the dd/mm/yy string that the RTC to ASCII V2 function creates as my file name if possible. at this point i am pre planning a project and do not have a physical controller to test. thanks ricardo

Hi all, I am using the UniStream 7'' PLC with UniLogic software. I set up my PLC as an FTP client and I am able to send files from the PLC to my PC via FTP just fine. My question is, is it possible to send entire folders via FTP from the PLC to a remote server as opposed to single files? Thanks in advance Amit.

Hi all, After downloading my latest changes I get a message on the screen saying "CPU Error Detected. Communications with the CPU cannot be established..." See attached screenshot for details. I have tried resetting the modules, have checked all the wiring, grounding etc. and can't find anything amiss there. Also, I can revert to an older version of the PLC and it will run for a short time before getting the Error message again. I'm not an expert with Unitronics but can't seem to find anything relevant in the forums or online. Can anybody shed some light on this?

I created a global array of Binary. How do I set/clear/compare elements of the array of binary? I use Store to do that with array of integers, but that doesn't seem to work with a array of binary.

Is there way to convert STRING-ASCII to STRING-UTF16. I have data table with UTF-16 column for messages, but in one case I want to add number there, but number is in ASCII. Maybe someone knows some existing method for this kind of conversion ? I can probably create this function, but is UniLogic internally "Little endian" or "Big endian" ? Anatoly

I like to link different Data Tables (Indexed) to one Function as IN parameter. Has someone done this already? What I'm doing wrong? (Please see example Function1 Rung 1; Direct linking is possible Function1 Rung 2)

Hi Have a problem to copy my data table on my dok. First i copy my data table on the sd with the bloc "store dti to file" and after i use the bloc copy/move to transfer the value on my dok. But the statuts stay always at -3 ( invalid dok folder path) And i use the syntax given in help. On location D i write #"DT/" Thanks for help

I have two identical functions, except "Function In" has different array lengths. Inside function I can easily determine array length with "Array Size", but understandably "Function In" doesn't accept different array lengths. Is it possible declare "Function In" so it will accept different length of arrays ?? I figured if I declare short arrays they will accepts calls with longer arrays. Question, Is entire array accessible from function or only smaller subset ? -
Hello, I'm having a problem with a function which uses a timer for an input. I've got an application that uses multiple timers which all do relatively similar things. Basically, I have a display which shows the timers progression, so each timer needs to pass it's own preset and current values to the common variables I linked to the meter in the screen. Note that only one timer is active at a time, and the next timer starts when the previous timer ends, so I only need the one meter. I created all of the timers with the correct preset times, and I created a function with a timer input so that in

Hi, I am trying to produce basically a set of scales. Once the system is powered on and the bowl placed on top I would like to Tare the output. Here is an image of my ladder. Manually if I take the value now displayed in RealForce and enter it into ForceX1 my display goes to 0000. This is all good but now I am trying to find what I need to be able to do this by pressing a button on the screen. At present I am developing this on a USC-B10-TR22 but eventually will be transferring this to a V1210. Cheers KevB Leonardo Force Display.ulpr

Dear all, I have US5-B5-TA30 PLC with UIS-WCB2 modules and expansion adapter. I want to use PWM HSO for step control and set duty cycle, frequency and Target. In VisiLogic this was easy in HW Configuration setting High Speed Output (Step Control). In the attach you can find the example I made in VisiLogic. (LEVO - means left, DESNO - means right, on the display in the example). I am having troubles configuring the HSO on the WCB2 as PWM with target. I am relatively new to UniLogic, so please help. Thanks, BR HSO Proba - SAMBA.vlp

I'm looking for code examples to use on the UIS-WCB1_1 high speed counter. I have only found the wiring documentation for the module. And to confirm is the reset edge triggered or reset on True And there a total lack of input specifications. trial and error has me using Inp 1 for counter 1 and Inp 4 for counter 2 The info may be out there but its not jumping out at me
