Preliminary Operating Considerations

This chapter explains how the RTD module and the SLC processor
communicate through the module’s input and output image. It lists the
preliminary setup and operation required before the RTD module can
function in a 1746 I/O system. Topics discussed include how to:

enter the module ID code

address your RTD module

select the proper input filter for each channel

calculate the RTD module update time

interpret the RTD 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.

To manually enter the module ID code, select (other) from the list of modules
on the system I/O configuration display. The module ID code for the RTD
module is shown below:

No special I/O configuration information is required for Class 1. The module
ID code automatically assigns the correct number of input and output words.
For Class 3 the user must assign the correct number of input and output words
(16 and 24).
