Function
n+5 00 to Unit error code
07
Note: The error codes are also stored
in bits 00 to 07 of the error information
portion of error logs.
08 (Reserved by system.)
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 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 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).
12 (Reserved by system.)
13 (Reserved by system.)
14 Unit busy
OFF: The Unit is not busy.
ON: The Unit is busy (i.e., performing
initial processing).
15 Unit operating status
OFF: STOP (PROGRAM mode)
ON: RUN (RUN or MONITOR mode)
Note: When this bit is ON, the OPN
indicator on the front of the Unit lights.
