(there is an endless loop in the program or the load capacity of the PLC is exceeded). At this time, set dial 2 to
ON (power on does not load the user program), and scan the connected device again. If the connection can be
scanned, an empty program will be downloaded at this time. After the abnormal program is erased, the dialing
status will be restored. At the same time, check the abnormal program (whether there is an excessively long
cycle or the task cycle time is too small).
