Appendix 4 List of Special Relay Areas
SM1653 Memory copy start Off: Not started
On: Start • When this relay is turned from off to on, the
memory copy from the control system to the
standby system starts. Note that the
memory copy does not start as long as the
I/O number of the copy destination (standby
system CPU module: 03D1H) is not stored
when SM1653 is turned from off to on.
• Initial value is off: The memory copy has not
started.
U RnP
SM1654 Memory copy being
executed Off: Not executed
On: Being executed • This relay is on during the memory copy
from the control system to the standby
system.
• This relay turns off when the memory copy
is completed.
S (Status change) RnP
RnPSF
SM1655 Memory copy
completion Off: Not completed
On: Completed • This relay turns on at the completion of the
memory copy from the control system to the
standby system.
• Initial value is off: Memory copy has not
completed.
S (Status change)/U RnP
RnPSF
SM1656 Auto memory copy Off: Disabled
On: Enabled This relay turns on when the automatic
memory copy is set to enable. S (Initial) RnP
SM1673 Tracking transfer
completion flag Off: Transfer not completed
On: Transfer completed • This flag is stored a result of the tracking
transfer operated in the preceding END
processing.
• The flag turns on if any of the tracking
transfers in block 1 to 64 has been normally
completed, and turns off if the tracking
transfers failed due to causes such as
tracking communication error.
S (Status change) RnP

system) Off

• This relay is turned from off to on to clear a
continuation error occurred in the standby
system.
• This relay turns from on to off when the
error reset has been completed.
• Initial value is off.
U/S (Status change) RnP
RnPSF
SM1680 Error of the other system
monitoring Off: No error
On: Error • This relay turns on if an error occurs on
communications with the other system
when an initial processing (including when
the system is determined while waiting for
the other system starts up) or an END
processing is performed. (This relay turns
on when the bit of SD1648 turns on.)
• This relay turns off when an error is cleared.
S (Initial/every END/
system switching) RnP
RnPSF
SM1681 Latest self-diagnostic
error (including
annunciator ON) (the
other system) Off: No error
On: Error • This relay turns on if a diagnostic error
occurs in the CPU module in the other
system. (The relay also turns on if an error
is detected by an annunciator.)
• The SM0 status for the CPU module in the
other system is reflected.
S (Every END) RnP
RnPSF
SM1682 Latest self-diagnostic
error (not including
annunciator ON) (the
other system) Off: No error
On: Error • This relay turns on if a self-diagnostic error
occurred in the CPU module in the other
system. (The relay remains off if an error is
detected by an annunciator.)
• The SM1 status for the CPU module in the
other system is reflected.
S (Every END) RnP
RnPSF
SM1683 Detailed information 1:
Flag in use (the other
system) Off: Not used
On: In use • This relay turns on when there is detailed
information 1 for an error occurred in the
CPU module in the other system.
• The SM80 status for the CPU module in the
other system is reflected.
S (Every END) RnP
RnPSF
SM1684 Detailed information 2:
Flag in use (the other
system) Off: Not used
On: In use • This relay turns on when there is detailed
information 2 for an error occurred in the
CPU module in the other system.
• The SM112 status for the CPU module in
the other system is reflected.
