Operation
Event code Overview
24000 Data link startup instruction
24001 Data link stop instruction
24100 Own station: Parameter change/new parameter
acceptance

detection
Cause
Baton pass of the own station was returned from interruption status to normal status.
Baton pass of another station was returned from interruption status to normal status.
Baton pass was returned to normal status at all stations.
Data link of the own station was restarted.
Data link of another station was restarted.
Data link was returned to normal status at all stations.
Data link startup of the own station instruction was received.
Data link stop instruction of the own station was received.
Loopback execution status was resolved when using a ring topology (using the
loopback function).
A parameter error received from the control station was resolved. (Normal parameter
was received.)
A system switching request occurred.
Baton pass of the own station was interrupted.
Baton pass of another station was interrupted.
• Abnormal response was returned from another station when accessing another
station.
• Abnormal response was returned to another station when accessed from another
station.
Data link of the own station was stopped.
Data link of another station was stopped.
A parameter error has occurred in another station.
An error has occurred in the CPU module on another station.
Path switching has occurred when using a ring topology (using the loopback
function).
A parameter error received from the control station has been detected.
Cause
Data link startup to the own station or another station was instructed.
Data link stop to the own station or another station was instructed.
Parameter was changed. Or new parameter was received at power-on.
Operating status of the programmable controller CPU on another station was
changed.
