Dear Expert,

I am using 300 Series PLC & I want to send data to BMS. BMS Part communication mentioned is Smartlink Ethernet.

So Which Communication  module in 300 Sreies PLC  is required for Smartlink Ethernet communication.

Hello RAJKIRAN

Which Device or Module do you want to communicate to from the S7300?

Hello Rajkiran;

Have you started by looking for information on the Smarlink Ethernrt support from Schneider? Have you contacted anyone from Schneider to find out if this communication setup is compatible with a Sienmens CPU in any way?

Although I doubt that you could connect the S7 CPU with Smatlink Ehernet directly, it seems that it is possible to connect Modbus RTU or Modbus/TCP I/Os to smartlink Ethernet hardware:

If you beleive that is a possible solution, you would need either a combination of:

- CP 3141 (Serial, RS-485) with a Modbus RTU license (6ES7870-1AB01-0YA0)

- CP 343-1 with a Open ModbusTCP license (2XV9450-1MB00)

Hope this helps,
