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.
Module ID Code 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.
Use the system I/O configuration display to select the 1746-INT4
module or manually enter the module ID. Do this by selecting Other
from the list of modules on the system I/O configuration display and
enter 3515, the ID code for the 1746-INT4 module.
No special I/O configuration is required. The module ID automatically
assigns the correct number of input and output words.
