Class StoAi
Version 1.0
Modified 08-MAR-2026 11:05:32.00
Code rt_plc_macro_io.h 
 Store Analog input.


 Stores an analog value ( e.g. output signal of the type
 pwr_tFloat32) on the specified local Ai object.

 The complete name of the Ai object has to be supplied;
 its last segment is shown in the right empty part of
 the symbol.
Note!
 This object is used for simulation purposes.
 SimulFlag will be set TRUE and ReadWriteFlag FALSE
 in the IOHandler object, i.e. any physical I/O-hardware may
 not be used on the node in connection to this object.
RtBody attributes pwr_sClass_stoai
Float32 In VAL The input is connected to an analog signal or left
open. In the latter case In is default 0.0 and not
adjustable in the run time system. The In attribute
specifies which value should be assigned to the
Ai-signal.
DevBody attributes 
AttrRef AiObject In Used by the PLC Editor. Specifies the complete name of
the current 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 StoAi 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 StoAi 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 StoAi object. The
segments are counted from behind.
0 and 1 both result in displaying the last segment of
the channel object name.
