• When the Safety CPU is powered on or is
reset
• When an error is cleared
• This relay switches to on if a cycle in which
safety cycle processing was not executed is
detected.
• Once the relay turns on, it remains on even
if the safety cycle processing is performed
each cycle. (To turn off the relay, power off
and on the system or reset the CPU
module).
• This relay stores the CC-Link IE Field
Network safety communication setting
status.
• When safety communications are available
(the relay is on), the start I/O number of the
target module is stored in SD1904.
• This relay stores the CC-Link IE Field
Network safety communication setting
status.
• When safety communications are available
(the relay is on), the start I/O number of the
target module is stored in SD1905.
• This relay stores the CC-Link IE Field
Network safety communication setting
status.
• When safety communications are available
(the relay is on), the start I/O number of the
target module is stored in SD1906.
• This relay stores the CC-Link IE Field
Network safety communication setting
status.
• When safety communications are available
(the relay is on), the start I/O number of the
target module is stored in SD1907.
• This relay stores the CC-Link IE Field
Network safety communication setting
status.
• When safety communications are available
(the relay is on), the start I/O number of the
target module is stored in SD1908.
• This relay stores the CC-Link IE Field
Network safety communication setting
status.
• When safety communications are available
(the relay is on), the start I/O number of the
target module is stored in SD1909.
• This relay stores the CC-Link IE Field
Network safety communication setting
status.
• When safety communications are available
(the relay is on), the start I/O number of the
target module is stored in SD1910.
• This relay stores the CC-Link IE Field
Network safety communication setting
status.
• When safety communications are available
(the relay is on), the start I/O number of the
target module is stored in SD1911.
