Memory Areas Appendix C
AR 11 00 to 15 4 digits BCD
Power supply cut frequency.
---
AR 12 00 to 15 Not used.
AR 13 00 Power-up PC Setup Error Flag
Turns ON when there is an error in DM 6600 to DM 6614 (the part of the PC Setup area
that is read at power-up).
3
01 Start-up PC Setup Error Flag
Turns ON when there is an error in DM 6615 to DM 6644 (the part of the PC Setup area
that is read at the beginning of operation).
02 RUN PC Setup Error Flag
Turns ON when there is an error in DM 6645 to DM 6655 (the part of the PC Setup area
that is always read).
03, 04 Not used.
05 Long Cycle Time Flag
Turns ON if the actual cycle time is longer than the cycle time set in DM 6619.
---
06 Turns ON when the program memory (UM) area is full. ---
07 Turns ON when instructions other than those in the support software area used. ---
08 Memory Area Specification Error Flag
Turns ON when a non-existent data area address is specified in the program.
---
09 Flash Memory Error Flag
Turns ON when there is an error in flash memory.
---
10 Read-only DM Error Flag
Turns ON when a checksum error occurs in the read-only DM (DM 6144 to DM 6599)
and that area is initialized.
3
11 PC Setup Error Flag
Turns ON when a checksum error occurs in the PC Setup area.
12 Program Error Flag
Turns ON when a checksum error occurs in the program memory (UM) area, or when an
improper instruction is executed.
---
13 Not used. (Cleared when power is turned on.)
AR 13 14 Data Save Error Flag
Turns ON when power is turned on if data could not be saved in the following areas:
DM area (read/write-capable), HR area, CNT area, SR 252, bits 11, 12 (when PC Setup in DM
6601 is set to maintain status), error log, operation mode (when PC Setup in DM 6600 is set to
continue mode last used before power failure).
(For details regarding the holding time, refer to the SRM1 Operation Manual.)
If data could not be saved in the above areas:
The DM (read/write-capable), error log, HR, and CNT areas, and SR 252, bits 11 and 12 will be
cleared. The operation mode will go into Program Mode.
15 SRM1 CompoBus/S Communications Error Flag ---
AR 14 00 to 15 Maximum Cycle Time (4 digits BCD)
The longest cycle time since the beginning of operation is stored. It is cleared at the
beginning, and not at the end, of operation.
The units can be any of the following, depending on the setting of in DM 6618.
Default: 0.1 ms; “10 ms” setting: 0.1 ms; “100 ms” setting: 1 ms; “1 s” setting: 10 ms
21
AR 15 00 to 15 Current Cycle Time (4 digits BCD)
The most recent cycle time during operation is stored. The Current Cycle Time is not
cleared when operation stops.
The units can be any of the following, depending on the setting of in DM 6618.
Default: 0.1 ms; “10 ms” setting: 0.1 ms; “100 ms” setting: 1 ms; “1 s” setting: 10 ms
