Compactlogix to S7-1200 communcation

Hi,

I'd like to ask what is the best to communicate method between CompactLogix (1769-L31) & Siemens S7-1200 1214-CPU?

There are space to add in additional module in the panel. The distance is about 60 meters from each other. Non high speed require.

Thank you.:site:

Hi Flyers,


Here is a thread about your problem:

One solution is to use a gateway. I guess that your Compactlocix has EtherNet/IP and the S7-1200 has Modbus RTU and If so Anybus gateway can solve it for you, see link below:

Also look at **** gateways, I've used these to connect ControlLogix to S7-300. They work by connecting to the PLC's and a little bit of simple script to transfer the data

I would go the modbus tcp route
It's probably built in to ab, I know it is with Siemens 1200

Guy,

Thanks for the advise. I browse thru some gateway/converters.

Is Prosoft Profibus module another method to communicate with Siemens S7-1200? We can add Profibus module at the S7-1200

Thank you.

There are several different ways to do this.

I would not use Profibus unless you need high speed; it is both costly and complex to configure on the CompactLogix side.

Since the S7-1200 supports Modbus/TCP, I would recommend a gateway device that supports both Modbus/TCP and Allen-Bradley DF1.

The Digi One IAP and HMS Communicator, as well as the Red Lion DataStation Plus are the first few that come to mind.
