Map Descriptor Examples

This example shows the transfer of I/O data with Remote PROFIBUS DP Slaves using Station Addresses
of 1 and 125.
Map Descriptor
Map_Descriptor_Name , Data_Array_Name
Word_In_003 , Word_Input
Word_Out_003 , Word_Output
Byte_In_125 , Byte_Input
Byte_Out_125 , Byte_Output
, PROFIBUS_Data_Type , Address

If the device only has an input buffer:
Map Descriptor
Map_Descriptor_Name , Data_Array_Name
Word_In , Word_Input
Byte_In , Byte_Input
, PROFIBUS_Data_Type , Address
, Word , 0
, Byte , 0
If the device only has an output buffer:
Map Descriptor
Map_Descriptor_Name , Data_Array_Name
Word_Out , Word_Out
Byte_Out , Byte_Out
, PROFIBUS_Data_Type , Address
, Word , 0
, Byte , 0
If the device has both an input and an output buffer:
Map Descriptor
Map_Descriptor_Name , Data_Array_Name
Word_In , Word_Input
Word_Out , Word_Output
Byte_In , Byte_Input
Byte_Out , Byte_Output
, PROFIBUS_Data_Type , Address
, Word , 0
, Word , 0
, Byte , 0
, Byte , 0
The table below shows the map descriptor function that to use in the config.csv with a specific module.
A PROFIBUS Slave device will have one of three types of I/O Modules, Input, Output or Input/Output. The
I/O Module type can only be found by analyzing the GDS file of the device in a PROFIBUS Software
system.

Two Map Descriptors need to be configured, one for the input module and one for the output.
