00 to 07 Unit error
code
These bits are used to notify the CPU Unit of the error code
for errors that occur in the Customizable Counter Unit.
Example: CYCLE TIME OVER error (more than 10 ms): F8;
Unit Function Setting error: 9B; Cycle Monitor
Time Overrun error (more than the time set in DM
6618): 9F; FALS (fatal error) instruction execution
or FAL (non-fatal error) instruction execution: 01 to
99. (Refer to 9-3 Troubleshooting Tables.)
The error code is also stored in bits 00 to 07 of the detailed
information in the error log stored in the Customizable
Counter Unit.

09 Unit Cycle
Time
Exceeded
This bit is used to notify the CPU Unit when the cycle time is
exceeded in the Customizable Counter Unit.
OFF: No error (cycle time less than 10 ms)
ON: Cycle time exceeded (cycle time more than 10 ms)
Note Only valid when set to detect CYCLE TIME OVER er-
rors (set in DM 6655). SR 23509 turns ON when a
CYCLE TIME OVER error (more than 10 ms) occurs.
The Unit error code F8 is stored in bits 00 to 07 of word
n+5 in the CPU Unit (and consequently SR 23500 to
SR 23507 in the Customizable Counter Unit).
10 Unit
non-fatal
error
(including
FAL
execution)
OFF: No non-fatal error
ON: Non-fatal error occurred (e.g., Unit function setting
error, CPU Unit fatal error)
11 Unit fatal
error
(including
FALS
execution)
OFF: None of the errors below have occurred.
ON: One of the following errors has occurred:
FALS instruction executed; no END instruction; error
with special I/O, Cycle Monitor Time Exceeded (set in
DM 6618 in the Unit Setup Area).

14 Unit busy This bit indicates whether or not the Customizable Counter
Unit is busy.
OFF: The Unit is not busy.
ON: The Unit is busy (i.e., performing initial processing).
15 Unit
operating
status
This bit is used to notify the CPU Unit of the operating status
of the Customizable Counter Unit.
OFF: STOP (PROGRAM mode)
ON: RUN (RUN or MONITOR mode)
Note When this bit turns ON, the OPN indicator on the front
of the Unit lights.
