i need to connect an intelligent MCC (like simocode) to a 99.9% available control system.
I need to know of any intelligent MCC makes who have two communication ports for say profibus or modbus?

 

Why would you need two communication ports? The standard solution to your problem is a Y-link, that has two profibus connections going to your redundant control system and one going to the non redundant control modules, like simocode. To increase availability of the installation, a second motor (pump?) on a seperate profibus network and with power from a different transformer is generally the best solution.

 

Have you looked at the Square D/Schneider Electric offering at "http://www.squared.com":http://www.squared.com ? Search for Model 6 OMNI Center. They offer Modbus Plus, Profibus, Fipway, and others.

For multi-port multi-platform communications try the MUCM module from Niobrara R&D at "http://www.niobrara.com":http://www.niobrara.com
