My version of CX-P is 9.42 - you should update yours online. Apart from that I have never seen that error before. You need to make sure the I/O unit setting is the same as the old one. You also need to make sure the card is set up the same as the old one - go online to the card and set the type, speed and bits for the serial port - the PLC will need to be in program mode. You will also need to download any Protocol Macros such as Modbus RTU into the card if they were in the old card with CX Protocol.
