Communications

Fieldbus / Protocol

Communication networks allow large amounts of

data to be transferred quickly to and from network

nodes. Using a network fieldbus can significantly reduce

system wiring requirements and installation costs, while

enhancing wiring integrity.

The CT fieldbus interface modules and cards provide

high-speed communications with the popular networks

and protocols. Each interface uses RS485 isolated

communications for inter-drive voltage isolation and

noise immunity.
