Module Id Code - Allen-Bradley B Series User Manual

Module ID Code

Allen-Bradley
Publication 1746-6.16 – January 1999
Preliminary Operating Considerations
This chapter explains how the module and the SLC processor
communicate through the processor's I/O image tables. It also
describes the module's input filter characteristics. Topics discussed
include:
module ID code
module addressing
input channel characteristics
response to slot disabling
The module ID code is a unique number assigned to each type of
1746 I/O module. The ID defines for the processor the type of I/O
module and the number of words used in the processor's I/O image
table.
With APS software, use the system I/O configuration display to
manually enter the module ID when assigning the slot number during
configuration. Do this by selecting
modules on the system I/O configuration display and enter 3515, the
ID code for the 1746-INT4 module.
No special I/O configuration
module ID automatically assigns the correct number of input and
output words.
If you are using a different programming software package, refer to
the documentation that came with your software.
