Mapping and Accessing
RIO Network Data
Use the provided AbRioCfg software to create tags which are arrays of
digital, floating point or text values that the host controller reads or
writes using unscheduled messages.
You map data that the module receives or sends into these tags. The
data mapping is stored in flash memory on the 1757-ABRIO module.
The 1757-ABRIO Module and Data Mapping
WARNING
It is essential that the control program on the host controller
matches the addresses in the mapping configuration on the
1757-ABRIO module. Otherwise the control program may
inadvertently write to the incorrect I/O locations. If you change
the data mappings on the 1757-ABRIO module, make sure that
the control program is using the correct addresses.
