eType: Type of application object, ASDU identifier (e.g..: M_SP_NA_1 for Single Point or M_DP_NA_1 for Double Point ).

objAddr : Object address, any address can be given.

group: Object group configuration flags. See: Description of all Group Flags. The flags can be combined with OR-Linking. Not all combinations are sensefull!

multiplier: Base cycle time multiplicator for cyclic/periodic data transfer.  0 = disabled. The base cycle time can be configured by the tPerCyclicBase- parameter in the  system parameters. 

ioMapType: TwinCAT PLC process data range. This parameter defines how the TwinCAT PLC and IEC applicatation object process data are to be mapped.

byteOffs: TwinCAT PLC process data byte offset.

bitOffs: TwinCAT PLC process data bit offset.

dbEntry: Application object to be configured (array element).

Example in ST:

Configuration of three datapoints as linear table entries.
