Issue
Programme a DI point into an S-UNC-AI Card
Environment
S-UNC-AI Card
Cause
It is possible to programme a Digital Input object at an Analogue Input hardware location and the software will treat it as a digital input.
Resolution
If you are using the latest AI Card (from production code 200705) then no additional hardware is required, but the board must be left configured for "Resistive".
Older versions of the board required the addition of a Digital Input module (579-1-359), which is now obsolete.
