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.
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.
Module ID Code 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, 1746-NR4, is 3513.
No special I/O configuration information is required. The module ID
code automatically assigns the correct number of input and output
words.
