Preliminary Operating Considerations

This chapter explains how the thermocouple module and the SLC

processor communicate through the module’s input and output image.

It lists the preliminary setup and operation required before the

thermocouple module can function in a 1746 I/O system. Topics

include:

• Module ID Code

• Module Addressing

• Channel Filter Frequency Selection

• Update Time

• Channel Turn-On, Turn-Off, and Reconfiguration Times

• 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.

The module ID code for the thermocouple module is shown below:

No special I/O configuration information is required. The module ID

code automatically assigns the correct number of input and output

words.
