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

produces one byte of
input data and uses one
byte of output data.

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.
