ATTENTION: The non-redundant controller IOTA (51307198-
175) must be at hardware version ‘B’ or later to work with
expansion I/O modules. The hardware version is detailed on the
controller IOTA label.
Expansion IOMs and CPMs communicate via a ring topology
providing two link paths. If the running link path breaks, the other link
path re-establishes communication within in 250ms.
Right End Plate
A right end plate is required at the end of each row of expansion I/O
modules including the row connected to a controller. It allows
additional rows to be added or terminates the I/O link. The right end
plate has two Ethernet ports and a left expansion connector, as
numbered in the following picture.
