[Countermeasure]
$BD_INFO_T[n].$LAG_EM_BUF[m] (n=1-4, m=1-4) may not have been set correctly. Check the DeviceNet-related settings. If the problem is not resolved, before performing other operations (power-off or jogging) after the alarm occurs, use the abnormal-state recording function (‘Abnormal State Record’ in the auxiliary menu) to obtain an image backup and contact the service center. If the abnormal-state recording function cannot be used, record the conditions and operating steps up to the alarm, obtain an image backup, and contact the service center.
