I'm trying to communiecate with the XRC with rs232 from a PLC and can't find out what calculation type the Checksum uses, any one got experience with it?

There is no communication with I/O and the RS232 port in an XRC robot. You need to have an Anybuss card (JANCD-XLF01B) with the PLC serial communication (CC-Link, Profi-Buss, Device-net...) to get I/O signals to a PLC on XRC. The RS232 port is only for data communication IF you bought that option.

Hi robodoc,
I don't need the I/O's, just need to write/chance variables through the plc, In the plc i need to send the command with a checksum which checksum does the xrc use like: SUM_8/16 , XOR 8/16 or an CRC.

Let me put it to you another way. The RS232 port on the XRC processor is for talking to a PC (not a PLC) with Motoman software.
