M580 with TM3BCEIP

[Oncom]

Hi,

is it possible to use TM3BCEIP (TM3 bus couple) in M580? in datasheet it support for Modbus end EIP.

possible Architecture: Redundant CPU, with low cost I/O.

Hello. Yes it is possible, through the use of DTMs. You can use a Generic Modbus TCP DTM to add the TM3 IO as a device in your M580 DIO (Distributed IO) network.

Not sure it is enough to have the IO scanner available in the controller. It will work, if you know how to reach the information in the TM3. I have found some information on the links below:

Modbus Server:

EIP Server:

yes I found that too. but I didn't found how to configure this TM3BCEIP without M251/241/262.

I was try to config by web browser, but it say "Bus coupler disabled" and I thought it should enabled by Machine expert with M251/241/262 CPU.

This is currently not supported...

Well i thought it would be as simple as scanning a Modbus TCP device in the network.

With a new firmware which will be release in June 2020 it will be possible to configure the module via web interface over EIP.

Yes. The TM3BC will have a configurator software available in June sometime. It will allow you to configure the Bus Coupler and attached IO and export it as on EDS file for the M580 (If your using EIP). You will also need to import the project file from the configurator software into the Bus Coupler as well
