Post by simotion on Pointer to Softmotion axis ^{CODESYS Forge talk (Post)}
In my projet I use Softmotion. There are several Softmotion axis (type SM_Drive_Virtual). In the Global Variable List I have an array of pointers to the adress of the Axis. Axis : ARRAY[1..iMaxCntAxes] OF POINTER TO AXIS_REF_SM3 := ADR(AX01_Axis), // [1 ADR(AX02_Axis), // [2] This works, but when compiling I get the message : . [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX01_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX02_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. Is there a way when initializing to force the hardware (softmotion axis) to first initialize and then the Global Variable List?

Post by kuuki on Losing focus of variable ^{CODESYS Forge talk (Post)}
Hi. Does anyone know how to fix a problem with losing focus of a variable in FBD editor. Sometimes when trying to edit variable name, array index, etc. in network, editor randomly exits "text edit mode" and variable is replaced by text you were typing.

Post by egau on Importing a library overrides parameters of a referenced library ^{CODESYS Forge talk (Post)}
Hi, In my CODESYS project (ABC.project), I’m using the MQTT library. I’ve also created a separate library (DEF.library) which itself references the MQTT library. In ABC.project, I’ve customized some MQTT parameters—for example, setting g_udiMaxPublishersAndSubscribers to 100 instead of the default value of 20. However, when I import DEF.library into ABC.project, the MQTT parameters get reset to their default values. I assume this happens because DEF.library still uses the default MQTT configuration, which then overrides my project settings. A straightforward workaround would be to manually align the parameter values in DEF.library, but that doesn’t feel like the right approach. Is there a better or recommended way to handle this situation? I'm using SP18 Patch3. Any insights would be greatly appreciated. Thanks in advance!

Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.
