Tag name expressed in PLC program. The data type of this
parameter is used to set the data format of the Data Array
if the EIP_Data_Type parameter is not specified.
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
further information.
Number of data elements to be mapped. If the number of
data elements exceeds the Map Descriptor length, the list
of data elements will be truncated and an error message
will be printed once per Map Descriptor.

This parameter is required only for read structures i.e.
where EIP_Service is Data_Table_Read.
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
