through CSx:0.5/15). SeeGeneral Channel Status Block on page 64 for
more information.
Maximum Scan Time
This word indicates the maximum observed interval between consecutive
program scans.
The controller compares each scan value to the value contained in S:22. If
a scan value is larger than the previous, the larger value is stored in S:22.
This value indicates, in 100 us increments, the time elapsed in the longest
program cycle of the controller. Resolution is -100 µs to +0 µs. For
example, the value 9 indicates that 800 to 900 us was observed as the
longest program cycle.
User Fault Routine File Number
