Ŷ There can be no more than 700 feet of cable connecting all baseplates in a system that uses
Remote baseplates.
Ŷ A Remote baseplate cannot stand alone. It must be connected to a system that has a CPU. The
CPU can be in a PLC or in a Personal Computer that is equipped with a Personal Computer
Interface Card (see Chapter 11).
Ŷ Remote capability is facilitated by the Remote baseplate’s built-in isolation between the +5
volt logic supply used by the I/O modules residing in the Remote baseplate and the supply for
the interface circuit associated with the I/O Bus Expansion Interface. Isolation helps prevent
problems associated with unbalanced ground conditions.
Ŷ Maximum number of Remote baseplates allowed per system depends on the type of CPU they
are used with. For CPUs 331, 340, and 341, the maximum is 4. For CPUs numbered 350 and
higher, the maximum is 7.
Ŷ Each remote baseplate has a 25-pin female D-type Expansion connector mounted at its right
end for connection to other baseplates.
Ŷ Remote baseplates are available in two sizes; 5-slot (IC693CHS398) and 10-slot
(IC693CHS392)
Ŷ A Remote backplane does not support the following intelligent option modules: PCM, ADC,
BEM330, and CMM. These modules must be mounted in a CPU baseplate. All other I/O and
option modules can be mounted in any type of baseplate.
Ŷ Remote baseplates are the same physical size, use the same type power supplies, and support
the same I/O and option modules as the Expansion baseplates.
Ŷ Each Remote baseplate has a Rack Number Selection DIP switch.
