I understand that several PLC companies have proprietary bus protocols. Does everything you have use MODBUS?

Vermin,

All the components works with Modbus/TCP, and the card that I'm using is model TSXETZ410.

I can communicate it with a Twido PLC via Modbus/TCP driver, but I can't with the Proconel Modules (www.proconel.com), communication is incorrect (Using the same communitacions setting in both cases)

Appreciate your help

Thanks

Greetings,

We have several PLC platforms with very different comm protocols here.

We have used DIGI to build some CUSTOM bridges to connect PLCs to process controllers that are no longer in production.

We Had to ship them one of the controllers, and they wrote the code into the converter for us at a very reasonable price.
