09 Unit CYCLE TIME OVER (non-fatal
error)
OFF: No error (cycle time less than
10 ms)
ON: CYCLE TIME OVER error (cycle
time more than 10 ms)
Note: Valid only when the system is set
to detect CYCLE TIME OVER (set in
DM 6655). When the cycle time is
exceeded (more than 10 ms), the Unit
error code F8 is stored in SR 23500 to
SR 23507.
10 10 Non-fatal Unit error (including FAL
instruction execution)
OFF: No non-fatal error
ON: Non-fatal error occurred (e.g., Unit
setup error, fatal CPU Unit error)
11 11 Unit fatal error (including FALS
instruction execution)
OFF: None of the errors below have
occurred.
ON: One of the following fatal errors
has occurred: FALS instruction
executed; no END instruction; special
I/O error, Cycle Monitor Time Exceeded
(set in DM 6618 in the Unit Setup Area).

OFF: The Unit is not busy.
ON: The Unit is busy (i.e., performing
initial processing).
