Class GetAi
Version 1.0
Modified 08-MAR-2026 11:05:32.00 
 Get Analog input.


 Fetches the engineering value for a specified Ai-signal
 from I/O-copied area. See PROVIEW/R Designer's Guide.

 The complete name of the Ai-signal has to be supplied;
 its last segment is shown in the right empty part of
 the symbol.

 The GetAi object
 - is a pure address reference to the I/O-copied area
   for Ai-signals,
 - contains no relevant information (=data) in rtdb,
 - is without executable code.
RtBody attributes pwr_sClass_GetAi
Float32 ActVal VAL Used by the PLC Editor.
DevBody attributes 
AttrRef AiObject VAL Used by the PLC Editor. Specifies the complete name of
the Ai object.
AttrRef SigChanCon   Used by the PLC Editor.
Int32 AiObjectSegments   Specifies how many segments of the Ai object name that
is to be displayed in the symbol of the GetAi object.
The segments are counted from behind.

0 and 1 both result in displaying the last segment of
the signal object name.
Boolean ShowSigChanCon   Specifies if the name on the channel object (
associated with the signal object) is to be displayed
in the symbol of the GetAi object or not. FALSE means
no displaying and TRUE displaying.
See also SigChanConSegments.
Int32 SigChanConSegments   Specifies, when ShowSigChanCon = TRUE, how many
segments of the channel object name that is to be
displayed in the symbol of the GetAi object. The
segments are counted from behind.
0 and 1 both result in displaying the last segment of
the channel object name.
