@eschwellinger do you have any examples of using a USB barcode scanner? I have read through the forums here and I am unable to find how to get the barcode data to populate in a text field without having to first click into the text field to activate it. Is there a library that allows you to access the barcode data? I am really new to this in general any help is greatly appreciated, hopefully you have a pretty clear example

Hi geoweil, have you tried to save changed values to remanent area or using a VAR RETAIN? After restart you have to initialize Counter with last remanent value. Depending on changes per cycle and the possibilitiy of your control unit to write remanent storage. Otherwise you need a buffering system to ensure save backup of last PI_Counter value. May you could read this Thread to get further help: https://forge.codesys.com/forge/talk/Engineering/thread/31e1c8349e/#bf48

Hello I can't find anything to read on the subject so I'll ask here. Up to now, when adding a (for example) Modbus Master, I've selected the version <= the RT version, so if I'm using SP13 Patch 3, I can use a library that doesn't exceed this. I've no idea if this is correct, but it's always worked. Can someone explain the 4.x.x.x libraries that have appeared; are they tied to a RT version? The controller I use is now at SP18Patch60, so should I continue to use 3.5.xxx or change? thanks

Hello! Opening a project from a python script given at the CODESYS command line does not work for me with a file based storage project. Example: Running projects.open("test.project", primary = True) works but converting the project to a file based storage project and then give the folder name as an argument to project.open Running projects.open("test.fbsproj", primary = True) does not work. We decided to work with file based storage for the project. Is there a scripting API for file-based storage to e.g. convert it while running the script back or how to open file based storage project with projects.open? Thank you! voffi

Post by gmau on RS232 Communication in CODESYS Control RTE V3
CODESYS Forge

(Post)
Hello, I would like to implement RS232 communication into CODESYS Control RTE V3. I was writing the program testing it on CODESYS Control Win V3, where it worked fine. When I changed it to RTE, the communication was on, but I cannot send the data between PLC and scale - there is no or little response from scale - mostly one time receive and that is it. On Win V3 it was working fine. I read that I am supposed to configure CODESYSControl file for a proper communication using RTE, but even after that I can not get a stable and working communication. I am attaching my CODESYSControl and CODESYSControlUser data below, as well as I am sending the code from communication function. The communication should be through COM1 port of PC. CODESYS Version: CODESYS V3.5 SP21 + (64-bit) Runtime + Version: CODESYS Control RTE V3 Version 3.5.21.0 / CODESYS Gateway V3 - x64 Version 2.5.21.0 I would be much gratefull for any help. Sincerely,

Post by andrej on Write to File on soft PLC winV3x64
CODESYS Forge

(Post)
Hello all, I would like to store some data in text file. I use the soft PLC Win V3x64, on Windows 10. I use the SysFile Library 3.5.17.0. If I store the file directly in the in the directory of the PLC i.e. in '/CODESYSControlWinV3x64/E1FA7ABE/PlcLogic/LogAU.txt' the file is correctly filled with the data. However, If I use an absolute path to a different directory no data is stored in the respective file. Despite the fact that the respective file exists and the Filehandler is correctly opened (see in picture _fdSysFHandle <> -1). // sFileName : STRING := 'LogAU.txt'; // STORES FILE IN ../CODESYSControlWinV3x64/../PlcLogic/LogAU.txt' sFileName : STRING := 'C/Temp/LogAU.txt'// DOES NOT WORK --------------------- // FILE DESCRIPTOR _fdSysFHandle := SysFile.SysFileOpen( szFile:= sFileName,am:= SysFile.AM_APPEND,pResult := ADR(_Result)); Does some have an idea where the problem is, resp. how I can get store a file in an arbitrary directory. Thanks a lot and kind regards Andreas

Trying to utilize the persistence manager, but system do not write to file and do not create the config file. System is a Linux SL, version 4.13.0.0 Problems with persistence/config started when I had other problems to go online, I deleted the config file and the persistent files, but the system will not re-create them. I have tried to remove/re-install the "PersistenceManager"-module, create the folder-structure myself. And also reinstall the linux-runtime but its clearly not working. Any help appreciated.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
