Post by wollvieh on Problem while updating to new runtime 4.11.0.0 ^{CODESYS Forge talk (Post)}
okay, no ideas. So i made a new fresh image for the raspberry, so far,so good. Licensing the new image was no problem. And, after having trouble while read write files on the raspberry pi, i found the solution for these file operations with the Variable ForceIecFilePath in the CODESYSControl.cfg file. Some people had that issue discussed in that thread : https://forge.codesys.com/forge/talk/Deutsch/thread/d2df08e587/

Post by ph0010421 on MQTT library ^{CODESYS Forge talk (Post)}
Hello I'm using the MQTT_Client_SL library. Very good so far. One of the inputs to the MQTTClient FB is hCert (RTS_IEC_HANDLE). Which function do I need to use to get this? Or do I add a FILE library? thanks

For a permanent change, you may need to update the PLC configuration file or set the IP at startup using retained variables.

Hi nano, thanks for your answer, it took me some time but finally it works - the make file provided by the SDK takes care of practically everything :)

Post by toby on Ethercat Servo Setup ^{CODESYS Forge talk (Post)}
Hi Everyone, I have a simple project with a single servo, but its my first time using Codesys and motion, so I'm a little confused and lost, I've tried to read the tutorial online, but I'm not having much luck sorry. Can I please ask for some pointers. I have a ComfilePi HMI (Raspberry Pi) communicating to a Omron R88D-1SN08H-ECT amplifier. Please see the attached project file (which is better for sharing, the project file, or a archive?). This file was simply for testing the motion of the servo before anything else is tested with it. The project simply rotates the servo 1 rotation when called for, but the speed can vary based on user input. Nothing much fancy. As yet, I haven't had any servo movement, no errors on the amplifier display. How do I link the motion FBs to the physical drive? Thank you very much for any help you can offer. I'm sorry if I'm doing something very stupid or basic and getting it wrong. Have a good day. Toby

Post by pernockham on AC Persistence - values are not read from file during start? ^{CODESYS Forge talk (Post)}
I swear I tested this like 20 times yesterday without success. Repeated it today and it works. Maybe the system needed a "real" power reboot? To note. To make a manual edit of a variable I tried some different approaches this is what worked for me. "system/online edited" gvl_var.example_variable REAL:F16#2FFB334H-4 767.7 "manually edited" (with runtime stopped followed by a "cold start" to read from file) gvl_var.example_variable REAL:790.1 (the system will use the manual value but will not set an equivalent "hex" value until next online edit/write cycle)

Post by umair on Code for reading 4 address to get 1 value of sensor (Ethernet IP) ^{CODESYS Forge talk (Post)}
Hi all, I want to ask, how do I write code to read multiple address for Ethernet IP communication protocol? Because this multiple address will produce one reading of a sensor that I am currently using. I want to read the value of the sensor. https://global.discourse-cdn.com/business6/uploads/wago/original/1X/7a79f4ad7ce474b9383b8550356d984defd9f3a0.png The addresses are in Byte. The 4 addresses are 89,90,91,92. Thanks in advance. Best regards, Umair

Post by sajid on NMEA Serial data read in Control win v3 x64 ^{CODESYS Forge talk (Post)}
I am using the SerialCom example program from the CODESYS website to read NMEA strings in CODESYS Control Win V3 x64 through a serial-to-USB converter. However, I occasionally receive only partial data or encounter errors in the received string. A screenshot of expected NMEA string attached for reference. Could you please advise on how to ensure the full NMEA string is received consistently? Error in strRead variable is <value of="" the="" expression="" cannot="" be="" retrieved=""></value>

Post by rockallsue on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Some developers export ST code manually and edit it in VSCode, then copy it back. However, a more practical approach might be using automation scripts (PowerShell, Python) to extract and inject code into the CODESYS project. You could also check if CODESYS Automation Server or CODESYS API allows better ST access for external tools. https://www.codesys.com/the-system/releases-updates-lifecycle/release-plan-roadmap.html Network drive issues are particularly painful. As a mitigation, you could try using local project storage with periodic cloud sync instead of directly saving to a network drive. Using Rsync or Syncthing for automatic but safe synchronization might reduce risks of file corruption.

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

I'd like to use same code/project in different devices. (RPi, PLC) I change some lines in some POU before compiling. (array size, file path, etc ) My question is How to define pragma that effects all ST-POU in project. Is it possible ? I've read this. https://help.codesys.com/api-content/2/codesys/3.5.12.0/en/_cds_pragma_conditional/
