Node Address 5 Input and Output Data
The RediSTATION operator interface at node
address 5 is a polled device that produces 1
byte of input data.
Remember that this node must be enabled in
the scan list before it may participate in I/O
communication with the communication module.
In map segment 1, input data is taken from the
poll response starting at byte 0, bit 0.
This input data is mapped to the communication
module’s input image table starting at word 1,
bit 8.
The number of bits mapped is 8.

The RediSTATION operator interface at node
address 5 is a polled device that receives a 1 byte
poll message containing its output data.
Remember that this node must be enabled in
the scan list before it may participate in I/O
communication with the communication module.
In map segment 1, output data is mapped to a 1
byte poll message starting at byte 0, bit 0.
This output data is mapped from the
communication module’s output image table start-
ing at word 0, bit 10.
The number of bits mapped is 1. Each
RediSTATION operator interface receives a bit for
its indicator light which is either on or off.
