PM554-r-ac (1TNE968900R0220) setup.
I can not connect to the plc via automation builder (standard V2.xx) only via Codesys directly. this rules out a serial comms issue. The error refers to wrong target ID, which i believe is because the controller selected in automation builder is not the same as the connected PLC. in codesys i have to select version 1.3 controller.
Im not up to speed with setting up the controller via Codesys as im new to these PLC, i woudl rather use the automation builder package.
any comments welcome.
For the selected CPU you have to use serial connection trough COM1 (or optional COM2).
Usually a TK503 programming cable is used (or USB to RS485 converter).
The default settings (if not changed during previous download) of COM1 are 19200, parity no, data bits 8, stop bits 1, motorola byteorder = yes
