About Threshold Values for Analogue Inputs

The module determines the channel state and the line fault status by comparing the

channel input current with defined threshold values. You can define your own

threshold values or use a set of default values. The values you choose for the module

are inherited by each channel; you can define different thresholds for individual

channels later.

Thresholds are specified in counts, with 0 (zero) being 0mA, 1,024 being 4mA, and

5,120 being 20mA.

Note: When the system is operational you should change these values only using an

on-line update.

The AADvance controller provides hysteresis on the thresholds for increasing and

decreasing values to prevent chatter. The Workbench updates the reporting values

during every application cycle.
