5.3.3 Server Specific Map Descriptor Parameters – Data Table Read/Write.

Column Title	Function			Legal Values
EIP_Service	The action to be performed.			Data_Table_Read,
				Data_Table_Write
	Tag name expressed in PLC program. The data type of this			Maximum		length		48
EIP_Tag_Name	parameter is used to set the data format of the Data Array
				characters.
	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
EIP_Data_Type*	the parameter is not set, the data type of the Data Array			Float, Uint16, Uint32, Bit,
	will be used. This is only applicable to Data Table Read			Byte, Boolean, -
	when FieldServer is the Server. Refer to Appendix A.4 for
	further information.
	Number of data elements to be mapped. If the number of			For	any	given		Map
	data elements exceeds the Map Descriptor length, the list
				Descriptor		there	can be
Length	of data elements will be truncated and an error message
			200		Floats,	400	Integers
	will be printed once per Map Descriptor.	Refer to
				or 800 Bytes
	Appendix C for further information.
	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,			Any 16bit Integer number
EIP_Structure_Handle*	i.e. all members are of type Byte, Uint16, Uint32 or Float
				e.g. 59592, 0
	etc. When this parameter is defined, the number of
	structure members must be specified as the length of the
	Map Descriptor.
