CompoBus/S is a high-speed ON/OFF bus for remote I/O communications.

Connecting a CompoBus/S Master Unit to the network allows remote I/O

communications between the PLC and Slaves. High-speed communications

are performed with 256 points in a cycle time of 1 ms max.

PROFIBUS (PROcess FIeldBUS) is an open fieldbus standard for a wide

range of applications in manufacturing, processing, and building automation.

The Standard, EN 50170 (the Euronorm for field communications), to which

PROFIBUS adheres, ensures vendor independence and transparency of

operation. It enables devices from various manufacturers to intercommunicate

without having to make any special interface adaptations.
