The %udd macro is used in the Event Handler to read the value of an UDD (User Defined Data variable). Text formatting parameters can be added at the end.
From AMC 11.02 also alphanumeric labeling can be used. Alphanumeric labeling will be cleared after reset.

Syntax

%chg(ON_txt,OFF_txt)

Returns "ON_txt" when the event goes ON, "OFF_txt" when the event goes OFF

Examples

Example 1: LOG "Door %1.dir is %chg(OPEN ,CLOSED)"

Result in System Log when event goes ON: - "Door 123 is OPEN"
Result in System Log when event goes OFF: - "Door 123 is CLOSED"


Example 2:

IF %chg(1,0)
LOG "Event goes ON"
stop
ENDIF
LOG "Event goes OFF"
