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 had done a similar search for systems to link profibus to MB+; serial to
profibus; and serial to MB. For your application try the following sources:

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)
Lantronix
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.

 

Hi

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.

A 3rd party vendor that manufacutures a device you are looking for is "Anybus". Their website is "http://www.anybus.com":www.anybus.com . They have a variety of devices for various protocols.

 

You can try the following in no particular order:
"www.antal.de":http://www.antal.de
"www.deutschmann.de":http://www.deutschmann.de
"www.hms-networks.com":http://www.hms-networks.com

If you want to go CANOpen to Profibus that can be done too.
