Preliminary Operating Considerations
This chapter explains how the analog output module and the SLC 500
processor communicate through the module’s input and output image.
It lists the preliminary setup and operation required before the
module can function in a 1746 I/O system. Topics discussed include
how to:
•
enter the module ID code
•
select the Class 1 or Class 3 interface
•
interpret communication between the SLC processor and the
output module
•
calculate the module update time
•
interpret the module response to slot disabling
Module ID Code The module identification code is a unique number encoded for each
1746 I/O module. The code defines for the processor the type of I/O
or specialty module residing in a specific slot in the 1746 chassis.
