If set, the data will be stored in the specified format which
may be different to the format of the tag being polled. If
the parameter is not set, the data type of the Data Array
will be used. This is only applicable to Data Table Read
when FieldServer is the Server. Refer to Appendix A.4 for

EIP_Structure_Handle*
This parameter is required only for read structures i.e.
where EIP_Service is Data_Table_Read. The driver
supports read structures having members of same type,
i.e. all members are of type Byte, Uint16, Uint32 or Float
etc. When this parameter is defined, the number of
structure members must be specified as the length of the
Map Descriptor.
