RediSTATION Input and Output Data Mapping
The RediSTATION 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 pages 4-12 to 4-15.
In the RediSTATION’s bits for the red and green buttons and the
indicator light status bit:
•
1 = ON
•
0 = OFF
RediSTATION operator interface
Two input bits from the RediSTATION 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.

The RediSTATION
operator interface
produces one byte of
input data and uses one
byte of output data.

One output bit for the RediSTATION’s
indicator light (on/off) will be mapped.
