Map_Descriptor_Name Name of this Map Descriptor
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
Section 4
Data_Array_Offset
Starting location in Data Array
0 to maximum specified in Section
4
Function

Rdbc, Wrbc, Wrbx
5.3.2 Driver Related Map Descriptor Parameters
Column
Title
Function
Legal Values
Node_Name Name of Node to fetch data from
One of the Node names
specified in Section 5.2
Data_Type
Data type
Discrete Inputs (%I)
Discrete Outputs (%Q)
Discrete Temporaries (%T)
Discrete Internals (%M)
Genius Global Data (%G)
Analog Inputs (%AI)
Analog Outputs (%AQ)
Registers (%R)
%SA Discrete
%SB Discrete
%SC Discrete
%S Discrete (%S)
Length
Length of Map Descriptor. Length may not exceed the table in the
PLC
1-1000
Address
Starting address of read block / write block. The 1st element of
each Data type Table is referred to as address one.
1 , 2 , 3
Positive whole numbers
Format*
BIT tables are normally read by reading whole Bytes at a time (If
the Length is 10 then 10 Bytes of data are read and placed in 10
Data Array locations). This parameter can be used to read BITs
instead. (If the Length is 10 then 10 BITs are read and each BIT is
stored in its own location.)
BIT, Byte
The format for %AI, %AQ
and %R cannot be changed.
GE_Func*
This parameter is only specified when a write Map Descriptor is
created to change the privilege level.
CPL, RW
