Up to 32 alphanumeric characters
Data_Array_Name
Name of Data Array where data is to be stored
in the FieldServer
One of the Data Array names from “Data Array”
section above
Data_Array_Offset
Starting location in Data Array
0 to maximum specified in “Data Array” section above
Function
Function of Client Map Descriptor
RDBC, WRBC
Node_Name
Name of Node to fetch data or write data to
One of the node names specified in “Client Side
Nodes” above
Data_Type
Data type
FLOAT, WORD, BYTE, BIT
DP_Buffer
Specify buffer in the DP card being accessed.

Address
Address in DP_Buffer being accessed,
expressed in byte offset
0-243
Note: When using Data_Type BIT, the address is in
bit e.g. from 0 - 1951
Length
Number of points in DP_Buffer being accessed,
expressed in points defined by Data_Type
1- 1952, depending on Data_Type
e.g. when Data Type is WORD and length is 10, it
means that 10*2 = 20 bytes are used in the buffer
