Post by gseidel on Using an Axis of an Axis Group in Torque Conctrol ^{CODESYS Forge talk (Post)}
Hi manuknecht, the axis group currently always writes the axis set torque values. If no dynamic model has been configured for the axis group, then the set torques are written to 0. The solution for your use case is to call SMC_GroupUpdate [0] before you call SMC_SetTorque on the axes. This way, the axis group will write 0 to the set torques in the call to SMC_GroupUpdate(), and SMC_SetTorque then will write the desired set torque. Best regards, Georg [0] https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_GroupUpdate.html

I can also add the kernel log messages from the same time. Seems like some kind of packet storm to the PLC?

you could try to uninstall 4.8.0.0 Package by the CODESYS installer - and reinstall (I would use current version) - this should solve it

Post by kevinl on RevPi Connect RS485 ^{CODESYS Forge talk (Post)}
I figured this out on my own with this logic: usually the Serial port on a Raspberry pi is on /dev/ttyUSB0 then you need to set linux.DeviceFile=/dev/ttyUSB in codesys you then must set com port to 1 so i assumed codesys subtracts 1 from the number and adds this to the filename... (in code it would look like this: var comPort : byte := '1'; linuxDevice : string := '/dev/ttyUSB'; filename : string; end_var filename := concat(linuxDevice, (to_string(comPort-1)); filaname then is /dev/ttyUSB0 RevPi uses ttyRS485 as Serial port so you must remove the last number from the name and set the com port to this number +1 i hope this is understandable ;-)

Because it starts listening on all interfaces, which is against security considerations.

Post by jdjennings1962 on Trouble accessing Math functions in OSCAT library ^{CODESYS Forge talk (Post)}
Hi all, I am trying to utilize the ARRAY_SDV standard deviation function, part of the Math group in the OSCAT library downloaded from the CODESYS store. My Codesys version is 3.5.19.10. When I add the OSCAT to my Library, it shows a subset of the library (Standard) as fully installed and signed (see pic). However, the Math functions are not in this Standard group. The Math functions I need can be viewed as source code in the full OSCAT_BASIC, though this the symbol next to this library suggests it is source only and not fully installed. When I try to declare an instance of the ARRAY_SDV function in a program, it is not known. I have tried reinstalling and Building . . . Any help would be greatly appreciated. Jeff

Post by askjong on Update variables when OPC UA Client updates. Error ID: 268468277 BadAttributeIdInvalid ^{CODESYS Forge talk (Post)}
Hi, I'm connecting to a OPC UA Server using the Data Soruce Manager OPC UA Client. This works well until the OPC UA Server updates and the OPC UA list doesn't match up when i did last clicked the "Update variables" to add variables. All the variables are still the exists and none are removed from the server, but more are added during the engineering process. The error message i get in CODESYS is "Error in OPC UA call BadAttributeIdInvalid, Error ID: 268468277". The issues is fixed when i press the "Update variables" button and just press ok without adding or removing any variables in the list. Is there a way to either automatically update the browsepath if it fails or on startup, or to trigger it by code?

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I am having an issue where the manual start/stop push buttons on the HMI are supposed to take the pumps/blowers out of auto. The logic I have attached works for the pumps, but not the blower. From what I can tell it is the exact same logic, but it is not writing a 0 to the Auto PB variable. Attached is the logic, cross reference list to show nothing else is writing to it, and the HMI screen. Any help? Am I missing something? I am using a Groov Epic PR1, my software version is 3.5 SP19 Patch 5 32 Bit.
