Hello everyone, Updating and converting an existing working Codesys Softmotion axis control project to the latest Codesys IDE and Softmotion version always gives the following error message during compilation. " [ERROR] sm3_basic, 4.18.0.0 (codesys): MC_MoveAbsolute: C0138: No matching 'FB_Init' method found for instantiation of SMC_MoveAbsRelPerformerImpl " -- Previously working version: Codesys IDE SP18.50, Softmotion 4.10.0.0 -- Later updated version with the error: Codesys IDE SP21.10, Softmotion 4.18.0.0 Has anyone encountered a similar issue? How can this be resolved? Regards, Imdat

Post by bmatlove on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
I'm trying to firm up alarming of axis faults. Declutter the code and figure out what's what. Diving into it, I see the AXIS_REF_SM3 function block provides uiDriveInterfaceError and dwErrorId, but I can't find any significance of these further than Drive interface error number Parameter number: 1014 and Drive specific error identifier, parameter number: 1031, respectively. Is there some corresponding appendix I could use to decode these? Also, is there any relation to the Error ID (of type SMC_Error) of the MC POUs? MC_Jog, MC_Reset, MC_MoveRelative, etc? If so, are the above errors redundant? Thanks in advance.

Post by aris on Modbus write via FB failure ^{CODESYS Forge talk (Post)}
Hi all, I am using CoDeSys V3.5 and a soft controller Win V3x64. I am trying to read a modbus slave via Function Blocks and not via the channels of the hardware tree for the Slave. I created some requests of type ModbusRequest and I notice that I can read Input Registers and Coils but I can not write Holding Registers and Coils. I am using the library IoDrvModbusTCP 4.1.0.0. When i just use a single modbus request with FC06 (or FC16), there is no request sent to the slave and although the xExecute takes its true value from a pulse of 2 seconds duration, I take almost every 3 minutes an error "TCP_COMMUNICATION_ERROR - 16#A5 - TCP Port. error. Request was not sent". My code is ok because if i change the function code for reading registers, everything works fine. Did anyone have this issue in the past? Thank you in advance.

Post by masmith1553 on SDO generation ^{CODESYS Forge talk (Post)}
If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

Post by mejak on Raspberry Pi USB HID RFID Reader - read ID in plc program ^{CODESYS Forge talk (Post)}
Hello, I have an RFID reader that is detected as a keyboard. While looking for information, I came across examples using visualization. I would like to read the ID without visualization or external code in python, only in PLC. I found on the forum that you can try reading directly from potru /dev/... https://forge.codesys.com/forge/talk/Runtime/thread/24b3527036/ How to read values directly in codesys? Or maybe there is another solution? Best Regards

Post by jmfernandes on OpenDir always in error ^{CODESYS Forge talk (Post)}
Hello I'm trying to use DirOpen to access a directory where then I can read/list the files inside. But I can't list any files because DirOpen.xError is always true. In eError the message is this: " ERROR_UNKNOWN Local library error ID (0: no error; 5101: time out)**** " I have in the file explorer the path 'C:\CodesysTest\Aluminium' and to make sure I also created in the plc a folder to 'prj/Recipes/Aluminium'. I tried using the different paths, but in both it happens the same thing.Inside the folder Aluminium there is two csv files, that I want to list. I added in the library manager CAA Files and CAA Types. I am using the example of https://content.helpme-codesys.com/en/libs/CAA%20File/Current/Examples.html#directory but not matter what I do, I can't get the list the names of the files. What am I missing?
