ST_IEC870_5_101AOCfg

ASDU object configuration parameters. These parameters are set during configuration of the data points ( F_iecInitAOEntry or F_iecAddTableEntry ) and should not be written directly from the PLC application.

group: Object group configuration flags. A description of all group flags can be found here. The flags can be combined with an OR operation. Not all combinations are meaningful!

multiplier: Basic cycle time multiplier for cyclic/periodic data transfer. 0 = deactivated. The basic cycle time can be configured via the tPerCyclicBase parameter in the system parameters.

ioMapType: TwinCAT PLC process data area. This parameter defines the mapping for the TwinCAT PLC and IEC application object process data.

byteOffs: TwinCAT PLC process data byte offset (x86 platform => max. 32 bit, x64 platform => max. 64 bit).

bitOffs: TwinCAT PLC process data bit offset.

hUser: Optional user handle. Freely definable value, also pointer (x86 platform => 32 bit, x64 platform => 64 bit).
