Analog I/O Units can be
connected.
The CPU Unit can receive
temperature sensor input from
either thermocouples or
platinum resistance
thermometers.
A CompoBus/S I/O Link Unit
can be connected to provide
CompoBus/S Slave functions.
A DeviceNet Link Unit can be
connected to provide
DeviceNet slave functions.
This switch determines
whether communications are
governed by the standard
settings or PC Setup settings.
