2.2 Remote I/O Station Modules

For the specifications of available remote I/O station modules, refer
to the instruction manuals for the CPU and LPU modules to which
they can be connected. Table 2-3 shows the instruction manuals
for such CPU and LPU modules.

Function
Are used to set a station number, which is the 2-digit
starting address of an I/O number.
The upper digit of the starting address is set with the
U-switch and the lower digit, with the L-switch.
Each sets a count of the number of input/output points
per slot (16, 32, 64, or 128) on the mount base.
Either fixes the partitioning of the mount base (when
shorted) or does not fix it (when open).
Sets the output status of each output module connected
to the remote I/O (RI/O) communication line either to
"Reset" or "Hold" so that those output modules will
automatically be placed in the set output state when the
RI/O line is accidentally broken, disconnected, or
de-energized.
Is used to connect the remote I/O line cable.
Terminals 1 and 4 are internally connected together.
This is also the case with terminals 2 and 5.
Is used to connect the remote I/O line cable.
Terminals 1 and 4 are internally connected together.
This is also the case with terminals 2 and 5.
Is shorted to terminate the RI/O line with the built-in
terminating resistor (150 ohms) when the remote I/O
station module is connected to one end of the RI/O line.
Depending on the type of RI/O line cable used,
however, a 100-ohm terminating resistor needs to be
connected for use in place of the 150-ohm one.
Is used to ground the shield of the RI/O line cable.
This terminal is internally connected to the SHD
terminals of both RI/O IN and RI/O OUT and needs to
be wired to the FG terminal of the mount base.
Is lit when a remote I/O transfer operation is in
progress.
