Wired Remote I/O Systems
A Master is mounted to the CPU Rack or an Expansion I/O Rack; a Slave is
mounted to a Backplane to form what is called a Slave Rack. To a Slave
Rack is mounted the same other Units as those mounted to the CPU or Ex-
pansion I/O Rack, with only a few exceptions (e.g., Link Units other than
Slaves cannot be mounted to Slave Racks). The advantage of a Slave Rack
is that it can be located a considerable distance from the CPU Rack with the
only connection required being a cable running from the Master to the Slave.
The actual distance a Slave Rack can be removed from the Master, as well
as the other Units used to configure a Remote I/O System, depends on the
type of Remote I/O System being used. Collectively, all of the Units con-
nected in a Remote I/O System are referred to as Remote I/O Units.
This manual describes Wired Remote I/O Systems. Optical Remote I/O Units
are described in the Optical Remote I/O System Manual (W136).
In a Wired Remote I/O System, the Master is connected to other Remote I/O
Units through wire cable. These Remote I/O Units include Wired Masters,
Wired Slaves, and Remote Terminals. Link Adapters can also be included in
the System to enable the use of optical cable links.
A basic Wired Remote I/O System is shown below.
A Remote Terminal can be used when there is only a limited number of I/O
points required in a single location. Each Remote Terminal provides up to 16
input or output points.
There are two basic types of Remote Terminal. A G72C Remote Terminal is a
‘stand-alone’ Unit that occupies one location in the Remote I/O System. It
provides 16 fixed transistor inputs or outputs and can be used for any appli-
cation suited to these.
