Post by gmau on RS232 Communication in CODESYS Control RTE V3 ^{CODESYS Forge talk (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,

I can import some OPC UA information models, allright. Like the UA (core), Scheduler and PNEM models, etc. However, when I try to import the ECM model (Energy Consumption Managment), the Codesys IDE goes down after a while. Any clues?

Put %f in the "text" field and rValue in the "Text variable" field. You could also have a look at the possible placeholders: https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_placeholder_with_formatting_sequence_in_a_string.html

in case you are using latest hw revision, there have been added some mac adresses - for the 4.17.0.0 release this might solve it. If not we need to investigate deeper. If it is application related you need to check the plclogger.

I am using a new project, with nothing, but when add a simple cam table, and compile, there will be errors. It seems some add-on or library was missing, but there is not any hint. Could you help, please.

Hi gseidel, Thanks a lot. My softmotion is 4.18,so the SM3_Basic version is 4.18 by default. When I change the version of SM3_Basic to 4.17,complie works good then. Thank you for your kindness.

Dear @gseidel, Thank you for your reply. The exact version of Codesys and its compiler was 3.5.21.20. The compiler version was fixed and could not be changed in project settings. Since I couldn't continue due to this compilation error, I temporarily overcame this issue as follows. -- I completely uninstalled Codesys 3.5.21.20 and completely deleted the Codesys folder in the C:\ProgramData folder. -- I restarted my computer and installed Codesys 3.5.19.70. -- I updated the Codesys Installer and all its add-ons to the latest versions. -- The project that was giving me the compilation error I mentioned before is now open with Codesys 3.5.19.70, compiled it, and successfully downloaded it on the device. -- I haven't encountered the same problem anymore. I think this issue is related to SP21 and its compiler. Frankly, I'd expect a project created with an older version to compile without errors after opening it with the latest Codesys version and updating all libraries. Regards, imdatatas
