Issue
Created a new lookup table for an analogue output (AO) object to provide 10% steps and not 1% steps. Displaying the object value always shows 1% steps.
Environment
Sigma Controller (All Versions)
Cause
The analogue output object value is the input value for the lookup table and the output of which is then passed to the A to D converter and then to the physical output.
Resolution
The value can be seen by a multimeter connected to the physical output.
If the value of the output needs to be displayed via the Sigma front end then a programmable object is required to process the lookup table and then cross referenced to a standard analogue output object (with the default lookup table).
Example of programmable object:
10 Xflo = POINT 0|51
20 YFLO = LOOKUP (1812, XFLO)
30 RETURN VIA TEXT 92 VALUE YFLO
Where POINT 0|51 is the control/input object and 1812 is the lookup table number.
