Sigma - Analogue Input card does not display the correct values.

Issue

The AI Objects were all operating correctly and then failed. Instead of showing 20.0 (default range) they all show their last recorded value. On testing the inputs, the devices return to a different value and then the Temperature detectors all read 150°C with the Heat Flow Rates at 0m3/hr.

Environment

AI

Analogue Input

Defaults

Out of range

incorrect values

Cause

The controller slot allocation is incorrectly configured to show the slot as being empty.

Resolution

  1. Correctly allocate the slot as being an AI
  2. Download the controller configuration
