The following data is input from the Customizable Counter Unit to the CPU
Unit.
CPU Unit
address
Customiz-
able
Counter
Unit word
Bits Name Function
n+5 SR 235 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.
08 (Reserved by
system.) ---
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
errors (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 (includ-
ing FAL exe-
cution) OFF: No non-fatal error
ON: Non-fatal error occurred (e.g., Unit function setting
error, CPU Unit fatal error)
11 Unit fatal
error (includ-
ing 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).
12 Memory card
transfer error 0: No error
1: Transfer error occurred
13 (Reserved
by system.) ---
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, or
transferring data to memory card).
15 Unit operat-
ing 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.
n+6 SR 236 00 to 15 General-pur-
pose input
data These bits are used to send general-purpose data from the
Customizable Counter Unit’s SR Area word SR 236 to
SR 239 to the CPU Unit.
n+7 SR 237 00 to 15
n+8 SR 238 00 to 15
n+9 SR 239 00 to 15
