Preliminary Operating
Considerations
This chapter explains how the analog input 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
•
address your 1746-NI8 module
•
select the proper input filter for each channel
•
calculate the module update time
•
interpret the 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.
Catalog Number ID Code
1746ĆNI8
3526 - Class 1 interface
12726 - Class 3 interface
Important: All programming software does not support
configuration for Class 3 operation.
•
Advanced Programming Software (APS) supports Class 3
configuration. After entering the ID code (12726), enter 16 input
words and 12 output words.
•
SLC 500 A.I. Series
t Programming Software supports Class 3
configuration. After entering the ID code (12726), enter 16 input
words and 12 output words.
•
RSLogix 500
t, version 1.30 or later, supports Class 3
configuration. After entering the ID code (12726), select Class 3
operation.
•
Earlier versions of RSLogix 500 will only support configuration
for Class 1 operation. Contact Rockwell Software for
information on upgrading your software.
