I am trying to connect a Modbus Plus Network to an existing Square D Symax network. I have an existing PC that has Sylink Card in it and the goal is to eliminate this PC and have Modbus Plus talk directly to the Symax network. Any Ideas on how this can be accomplished?

 

Use Quantum CPU (140CPU11303) and a Remote I/O module (140CRP93100). This can eliminate the needs of that PC.
CPU has one Modbus Plus port, which will acts as a node on your existing MB+ network.

You can connect the RIO head module to your Symax "island". You need to write a very simple code to access the network.

Good luck.

 

Check out the NR&D MEB Module (http://www.niobrara.com) This module supports two RS422/RS485 (Modbus and SY/MAX Protocol Support), Redundant Modbus Plus Ports and a 10BASET Ethernet Port (Modbus TCP/IP and SY/MAX Ethernet Protocols). The module does not have a direct connection to the SY/NET (Blue Hose). You will need to use a "Net-to-Net" limk between an existing 8030CRM5xx Network Interface Module (NIM) or directly connect to the SY/MAX RS422 Serial Port of the processor.

Regards,
Robert Willis

 

The Niobrara MEB-RT can bridge MB+ to SY/MAX serial or Ethernet. You can configure one of its RS-485 ports for Net-to-Net to bridge between one of your SY/NET NIMs and the MB+. As a bonus you can also bridge Modbus/TCP Ethernet to MB+ and SY/MAX.

We may have a solution for you but it would involve a Modbus connection, not a Modbus Plus connection. Our Omnii-Comm product can connect a Square D Sy/Max network to many other PLC's.
