Details
• This relay is turned on when the CPU module is required to
accept the service processing requests until the time or rate
specified in "Device/Label Access Service Processing
Setting" in "CPU parameter" elapses. (The scan time will
increase according to the specified time or rate. When
"Specifying Method" is set to "Set Processing Counts" or
"Execute END Processing between Programs", the CPU
module does not wait for the device/label access service
processing regardless of the on/off state of this relay.)
• This relay is turned off when the CPU module is not
required to wait for the device/label access service
processing in END processing when there are no requests.
(Default: Off)
• The device/label access service processing constant wait
function is not enabled unless "AFFFH" is stored in SD315
(Service processing constant wait status setting) while
SM315 is on, and the CPU module does not wait for the
device/label access service processing.
• This relay is turned from off to on to send a setting request
and write/delete data to/in the setting storage area (system
memory) with the value set in SD384.
• Regardless of whether it was successful or not, this relay
turns off when the setting request is accepted.
• This relay turns on when writing into the setting storage
area (system area) fails.
• This relay indicates the LED control setting status of
program restoration information.
• This relay indicates the write status of program restoration
information in the CPU module.
• This relay turns off when all program restoration
information is written.
• This relay turns on if there is any program whose program
restoration information is not in the CPU module.
This relay indicates the operating status of the file batch
online change.
