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.

opt: Reserved.

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.

bitOffs: TwinCAT PLC process data bit offset.

hUser: User handle. Freely definable 32-bit value.

ext: Reserved.
