1794-IF8IH I/O Profile
All Allen Bradley FLEX I/O modules have a sixteen word table of Real Time
Data (RTD) to be transferred between the controller and the I/O module.
Not all 16 words need be allocated. The IF8IH has the following RTD IO
Profile:
In addition to the RTD, the module uses EDT for Configuration and HART
data. The IF8IH has the following EDT IO Profile:
Configuration Parameters
The configuration is shown in the table below. These are normal module
configuration items and are sent to the module. Configuration is located at
