6.6.3.Map Descriptors Example

Only two Map Descriptors are allowed, one to transfer data to the Logix CPU and one to accept data from the Logix CPU.

// Server Side Map Descriptors
Map_Descriptors
Map_Descriptors
Map_Descriptor_Name,	Scan_Interval,	Function,	Node_Name,	IO_Data_Type,	DA_Name_Start4,	DA_Count,	Protocol_Type_ID
Input_BP_Image,	0.2s,	WRBC,	SlotServer_CPU,	REAL,	In_1,	2,	0
Output_BP_Image,	0.2s,	RDBC,	SlotServer_CPU,	REAL,	Out_1,	2,	0

The following Data Arrays section must exist for the above Map Descriptors:

// Data Arrays
Data_Arrays
Data_Array_Name,	Data_Format,	Data_Array_Length
In_1,	Float,	76
In_2,	Float,	76
Out_1,	Float,	76
Out_2,	Float,	76

The data format should be chosen to allow no loss of resolution with the chosen IO_Data_Type of the Map Descriptor, e.g. don’t use integer here if you intend transferring float data.

See the Data Arrays section for the maximum Data Array lengths allowed per IO_Data_Type chosen on the Map Descriptor.
