If the VersaMax PLC will have more than one expansion rack or one expansion rack that
uses an Isolated Expansion Receiver Module (IC200ERM001) as its interface to the
expansion bus, an Expansion Transmitter Module must be installed to the left of the CPU.
The Expansion Transmitter Module must be installed on the same section of DIN rail as
the rest of the modules in the main rack (rack 0).
