Considerations Before Using
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
• channel filter frequency selection
• channel turn-on, turn-off, and reconfiguration times
• response to slot disabling
The module ID code is unique number assigned to each 1746 I/O
module. The ID code defines the type of I/O module and the number
of words used in the processor's I/O image table.
The module ID code for the 1746-NT8 module is 3533.
No special I/O configuration is required. The module ID automatically
assigns the correct number of input and output words.
