Chapter 5 Monitor Remote I/O
The 1756-RIO DiagMon window displays showing the Active Racks,
Global Diag Counters, and Rack Diag Counters.
Active Racks Table
The Active Racks table shows which racks are present on the Remote I/O
network. Columns represent rack numbers from 1…76 octal. Rows represent
starting I/O groups. If the bit for a rack and starting I/O group is set, there is
a rack at that location. The Active Racks table does not show rack size.
A ‘1’ indicates that a rack is present at the rack number and starting I/O group
indicated. In the example above, there is a rack present at rack 0, starting I/O
group 0.
The ‘1’ in the Active Rack table
indicates a rack present at rack 0,
starting I/O group 0.
