(1) Diagnostic information
Special Relay List
Meaning
• This relay turns on if an error is detected by diagnostics.
(Also turns on if an error is detected by an annunciator or
the CHK instruction.)
• This relay remains on even after the system returns to
normal.
• This relay turns on if an error is detected by diagnostics.
(Also turns on if an error is detected by an annunciator.)
• This relay remains on even after the system returns to
normal.
• This relay turns on if an error is detected by self-
diagnostics. (Remains off if an error is detected by an
annunciator or the CHK instruction.)
• This relay remains on even after the system returns to
normal.
• This relay turns on if an error is detected by self-
diagnostics. (Remains off if an error is detected by an
annunciator.)
• This relay remains on even after the system returns to
normal.
information • This relay turns on if error common information data
exists when SM0 turns on.
information
information • This relay turns on if error individual information data
exists when SM0 turns on.
information
ON : Error reset • Conducts error reset operation.
• This relay turns on if there is at least one output module
whose fuse has blown.
• This relay remains on even after the system returns to
fuse normal.
• Output modules on remote I/O stations are also checked.
• This relay turns on if the status of the I/O module differs
from that registered at power-on.
• This relay remains on even after the system returns to
normal.
• I/O modules on remote I/O stations are also checked.
(2) System information
Special Relay List
Meaning
• The status changes to PAUSE if this relay is on when the
PAUSE contact turns on.
• This relay turns on when inputs/outputs are forcibly
registered by GX Developer.
• This relay is turned on to read clock data and store them
as BCD values into SD210 to SD213.
• When this relay turns on, the largest I/O number among
those of the mounted modules is read into SD250.
• Turns on if a CC-Link error is detected in any of the CC-
Link modules mounted. Turns off when the condition
returns to normal.
• Turns on if a CC-Link error is detected in any of the CC-
Link modules mounted. Remains on even after the
condition returns to normal.
