RediSTATION Operator Interface Input and Output Data Mapping
The RediSTATION operator interface has both inputs and outputs that
must be mapped. The input byte is mapped to the 1747-SDN module’s
M1 file and then to the SLC 500 processor’s input data file. The output
byte is mapped to the 1747-SDN module’s M0 file and then to the SLC
500 processor’s output data file.
The mapping procedure, using RSNetWorx for DeviceNet software, is
described on page 45.
RediSTATION Operator Interface
In the RediSTATION operator interface’s bits for the red and green
buttons and the indicator light status bit:
•
1 = ON.
•
0 = OFF.

Status Bit for
Indicator Light
One output bit for the RediSTATION operator
interface’s indicator light (on/off) will be mapped.
Two input bits from the RediSTATION
operator interface will be mapped: bit 1 for
the green Start button and bit 0 for the red
Stop button.
Bit 4 of the input byte indicates if the bulb
is missing.
