Special relays SM1000 to SM1255 are the relays which correspond to ACPU special
relays M9000 to M9255 after A to 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 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
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 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 QnACPU.
