Bits
00 to 07
The error code (2 digits) that is output to AR 253 bits 00 to 07 is output.
08 and 09
CPM2B-S operating mode
10
Not used.
11
UM area write-protection (Mirrors the status of PC Setup setting in DM 6602 bits 00 to 03.)
OFF: UM writable
ON: UM write-protected
12 and 13
Not used.
14
ON when a non-fatal error has occurred.
15
ON when a fatal error has occurred.
00 to 03
Not used.
04
ON when a battery error has occurred.
(Effective only when detection of battery errors is enabled with the PC Setup setting in
DM 6655 bits 12 to 15 set to 0.)
05
ON when a cycle time overrun error has occurred.
06
Not used.
07
ON when FAL(06) was executed or a PC Setup settings error has occurred.
(The FAL number is transmitted in bits 00 to 07 of the leading word.)
08
ON when a memory error has occurred.
09
ON when there isn't an END(01) instruction in the program.
10
Not used.
11
ON when an I/O Unit over error (too many Units) has been detected.
12 and 13
Not used.
14
ON when an I/O bus error has occurred.
15
ON when FALS(07) was executed.
(The FAL number is transmitted in bits 00 to 07 of the leading word.)
Note If words in any areas other than the IR area (IR 000 to IR 227) or LR area
(LR 00 to LR 15) are allocated to the I/O Link Read area, the data may not be
cleared even when the power is interrupted, possibly causing data from imme-
diately before power interruption to be read by the master. If this creates a
potential problem, use the following measures to eliminate the problem.
• When starting in RUN or MONITOR mode, configure the ladder program
so that the Read area is rewritten with appropriate data.
• When starting in PROGRAM mode, it will not be possible to take direct
measures at the slave. Monitor the status at the master and do not read
the data when the operating mode is PROGRAM mode.
When a fatal error occurs at a slave, the master may read data from immedi-
ately before the error. In this case also, monitor the status at the master and
do not read the data.
