Triconex 4211

Bus Systems and Power

Distribution Three triplicated bus systems are etched on the chassis backplane: the Tribus, the I/O bus, and the communication bus. The Tribus consists of three independent serial links which operate at 25 megabits per second. The Tribus synchronizes the main processors at the beginning of a scan. Then each main processor sends its data to its upstream and downstream neighbors.

I/O Bus

The triplicated I/O bus transfers data between the I/O modules and the main processors at 375 kilobits per second. The triplicated I/O bus is carried along the bottom of the backplane. Each channel of the I/O bus runs between one of the three main processors and the corresponding channels on the I/O module. The I/O bus can be extended between chassis using a set of three I/O bus cables.
