* 1: The special relay can be used in the Universal model QCPU whose serial number (first five digits)
is "10042" or later.
TableApp.80 Special relays not supported in the Universal model QCPU and measures to be taken(Continue)
Number
Name/Description
Measures to be taken
SM280
CC-Link error
Replace the relay with the I/O signals (Xn0, Xn1, XnF) of
the mounted CC-Link module.
SM330
Operation mode for low-speed execution type program
The Universal model QCPU does not support low-speed
execution type programs.Delete the corresponding parts.
SM331
Normal SFC program execution status
The Universal model QCPU supports only normal SFC
programs. Delete SM331 and SM332 which are used as
interlocks or replace them with SM321.
SM332
Program execution management SFC program execution status
SM390
Access execution flag
According to sample programs described in the manual of
each module, modify the program so that the module
READY signal (Xn) is used as an interlock.
SM404
ON for only 1 scan after RUN of low-speed execution type
programs
The Universal model QCPU does not support low-speed
execution type programs.Delete the corresponding parts
or replace them with the special relays for scan execution
type programs (SM402 and SM403).
SM405
OFF for only 1 scan after RUN of low-speed execution type
programs
SM430
User timing clock No.5 (for low-speed execution type programs)
The Universal model QCPU does not support low-speed
execution type programs.Delete the corresponding parts
or replace them with the special relays for scan execution
type programs (SM420 and SM424).
SM431
User timing clock No.6 (for low-speed execution type programs)
SM432
User timing clock No.7 (for low-speed execution type programs)
SM433
User timing clock No.8 (for low-speed execution type programs)
SM434
User timing clock No.9 (for low-speed execution type programs)
SM510
Low-speed execution type program executing flag
The Universal model QCPU does not support low-speed
execution type programs.Delete the corresponding parts.
SM551
Module service interval time read
The Universal model QCPU does not support the service
interval measurement function.Delete the corresponding
parts.
SM672
Memory card file register access range flag
When the Universal model QCPU accesses outside the
range of file registers in the memory card, an OPERATION
ERROR (error code: 4101) is detected.There is no
application for this special relay.Delete the corresponding
parts.
SM710
CHK instruction priority flag
The Universal model QCPU does not support the CHK
instruction.For the alternative method of the CHK
instruction, refer to Appendix 5.3.
SM734
XCALL instruction execution condition specification
The Universal model QCPU executes the XCALL
instruction even at the rising edge of execution condition,
too. There is no application for this special relay.Delete the
corresponding parts.
SM735
SFC comment readout instruction in-execution flag
The Universal model QCPU does not support the following
instructions:
• SFC step comment readout instruction
(S(P).SFCSCOMR)
• SFC transition condition comment readout instruction
(S(P).SFCTCOMR)
Delete the corresponding parts.
SM1780
*1
Power supply OFF detection flag
The Universal model QCPU does not store redundant
power supply system information in SM1780 to
SM1783.Delete the corresponding parts.(SM1780 to
SM1783 are always OFF.)
SM1781
*1
Power supply failure detection flag
SM1782
*1
Momentary power failure detection flag for power supply 1
SM1783
*1
Momentary power failure detection flag for power supply 2
