Do Schneider PLC's support Modbus TCP/IP?

6 posts in this topic

Hello

I need to use Modbus TCP/IP to control drive, at the moment I am trying to use Siemens.  I was wondering if it would be easier to use a Schneider, their website says the communications are TCP/IP.  Not sure if they mean Modbus TCP/IP.   I will only use a Schneider if it natively supports Modbus TCP/IP.

I found this picture. Which would suggest it does.

Schneider does support Modbus TCP. Here is the manual for the M340.

Do you know what model of PLC that you want to use? Even some of the micro PLC's will support Modbus TCP.

Modicon invented Modbus, and Modicon is part of Schneider now.  So yes, their PLCs can do it.  But so can almost every single PLC on the market.

Thanks for the replies.

I have an Allen-Bradley PLC and a Siemens PLC.  I have tried using them both to connect to the Modbus TCP/IP module, but with the AB Modbus TCP/IP code after modifying it. I get 200 errors and the Siemens doesn't look like it supports it properly (no memory type for the TCP connection).

Basically I was wondering if Schneider PLCs are easy to get the Modbus TCP/IP working.  Have either of you sent commands of Modbus TCP/IP and how hard was it?

Thanks guys.

I've made some progress with the Siemens PLC.  I might try and get that working, rather than buying a new PLC.
