RediSTATION Operator Interface Data Mapping
The RediSTATION has both inputs and outputs that must be mapped.
The input byte is mapped to the 1756-DNB module's input data file
and then to the Logix5550 controller's input image table. The output
byte is mapped to the 1756-DNB module's output data file and then to
the Logix5550 controller's output image table.
The mapping procedure, using RSNetWorx for DeviceNet software, is
described on pages 4-15 to 4-18.

The RediSTATION
operator interface
produces one byte of
input data and uses one
byte of output data.
In the RediSTATION's bits for the red and green buttons and the
indicator light status bit:
• 1 = ON
• 0 = OFF
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 can be commanded
on by the Logix 5550's ladder logic if the
indicator light bulb is burnt out or missing.
