Using an Expansion Cable
In the example a T9310 expansion cable assembly is used to connect the right-
hand I/O base unit to another I/O base unit and modules.

It is straightforward to make dual and triple I/O controller architectures. A
system can have a mixed level of redundancy, fault tolerance and safety
integrity levels to meet your business application needs without over-specifying
the I/O.
