Protocol conversion from CANopen to MODBUS


Thread Starter


Is it possible to convert the signals from CANopen protocol to MODBUS protocol using PLC
etc. We want to interface the system to our MAX-1000 DCS using MODBUS protocol.
I believe the Modicon Premium PLC can communicate both CANopen and Modbus (with additional modules). Perhaps you could build a bridge with a low-end Premium processor.

Other vendors of bridges I know of:
Prolinx (don't think they do CAN yet)
SST (Woodhead Connectivity)
NR&D (maybe they can do it with their universal communication module for
Quantum of Momentum)

Yes, as Mr K, said, you can use a Modicon TSX Premium PLC.

The minimum configuration should be a CPU 203 with a PCMCIA CARD TSXCPP100 and a communication module TSXSCY21601.

If you need more assistance, do not hesitate to make contact.

I would suggest using a CANopen CPU module from selectron systems which supports directly CANopen on one port and MODBUS RTU thru another RS232 port. Should you require any info. on the same, contact me.
