Hello,
We have a project with axc 2152 . in this project, we also used the IB IL RS 485 ECO. So, I did a test about the module communication.
There is a problem about it.
I used the function block ‘COM_IL_485_ECO_1 ’in the library ‘ComSerial_3’, when I called the FB and parameterized it, an error occurred.
‘the selected resource ‘axc-f-2152-1:PLC’’does not support the program organization unit’SHL_WORD’.
The software vesion is PLCnext Engineer 2019.3
PLC HW: 02 FW: 2019.3
thanks a lot !
