• If there are disconnected slave stations, handle as per the error details.
• If there are no disconnected slave stations, this may indicate a problem with
a device other than the device set as the master station, so check the
network connections.
• Always end data assurance of link devices by the task that started data
assurance of link devices.
• Either turn the power supply of this product OFF to ON or reset this product.
Corrective action
Set "Use" for "Clock data synchronization"?
