Issue 1, September, 04
I/O transceiver modules provide an interface between the
processor modules in the controller chassis and the I/O modules in
the I/O chassis. Three I/O transceiver modules are installed in the
three left slots of each I/O chassis.
Features
•
Three modules per I/O chassis for triple redundant operation.
•
Interfaces processor modules to I/O modules.
•
Hot replaceable.
•
Front panel indicators on each module show active and fault
status.
• TÜV certified for safety, Risk Class 5.
I/O transceiver modules are triple redundant and can be removed
and replaced without interrupting system operation.
Module Operation
A block diagram of a typical I/O transceiver module is shown in
Figure 1.
Each I/O transceiver module communicates with one of the three
processor modules in the controller assembly. During I/O
Safetybus communications, the control logic on the I/O transceiver
module reads the I/O chassis’ identification code from the I/O
commands and compares them to the chassis’ identification switch
settings. Appropriately addressed I/O commands are directed
along the chassis’ backplane Safetybus to the I/O modules.
