Automatic Mapping
The Auto Map Any Unassigned command automatically maps any unassigned
discrete or block transfer data to ControlLogix connections. Discrete data is
mapped before block transfer data. The longest blocks of data are mapped
first, from the lowest addresses up. Any previously-assigned addresses remain
unchanged.
On the 56RioCfg configuration tool dialog box, from the Map menu, choose
Automap Any Unassigned to automatically map all the data.
Any xxxs are replaced with an actual I/O address.
Manually Map Discrete (rack) Data
1. On the 56RioCfgScan dialog box, right-click on the rack, and select
Rack Map Discretes - Assign Manually.
