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.

No.
Name Function
1
Station no. setting
switches (STNO U
and L)
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.
2 I/O point count setting
terminal pairs
Each sets a count of the number of input/output points
per slot (16, 32, 64, or 128) on the mount base.
3
“Fix partitioning or
not” setting terminal
pair
Either fixes the partitioning of the mount base (when
shorted) or does not fix it (when open).
4
Output hold setting
terminal pair
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.
5
RI/O line input
terminal triplet
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.
6
RI/O line output
terminal triplet
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.
7
Terminating-resistor
setting terminal pair
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.
8
Shield terminal
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.
9 Remote I/O operation
indicator (RI/O) LED
Is lit when a remote I/O transfer operation is in
progress.
