Appendix 1 Special Relay List
APPENDICES
(10)A to Q/QnA conversion correspondences
Special relays SM1000 to SM1255 are the relays which correspond to ACPU special
relays M9000 to M9255 after A to Q/QnA conversion.
(However, the Basic model QCPU, Redundant CPU, and Universal model QCPU do
not support the A to Q/QnA conversion.)
These special relays are all set by the system, and cannot be set by the user
program.
To turn them ON/OFF by the user program, change the special relays in the program
into those of QCPU/QnACPU.
However, some of SM1084 and SM1200 to SM1255 (corresponding to M9084 and
M9200 to M9255 before conversion) can be turned ON/OFF by the user program, if
they could be turned ON/OFF by the user program before conversion.For details on
the ACPU special relays, see the user's manuals for the individual CPUs, and
MELSECNET or MELSECNET/B Data Link System Reference Manuals
POINT
The processing time may be longer when converted special relays are used with
the High Performance model QCPU and Process CPU. Uncheck "Compatibility
with A-PLC" within the PLC system setting in GX Developer parameters when
converted special relays are not used.
Remark
The following are additional explanations about the Special Relay for Modification
column.
When a special relay for modification is provided, the device number should be
changed to the provided QCPU/QnACPU special relay.
When is provided, the converted special relay can be used for the device
number.
When is provided, the device number does not work with QCPU/QnACPU.
