■Cause of error at abnormal completion
If the IP address storage area is not cleared correctly, the cause of the error is stored as follows:
Module Storage location
CPU module (built-in 'IP address storage area
Ethernet port part) clear error cause' (SD1527)
RJ71EN71, RnENCPU 'IP address storage area
(network part) clear error cause'
(Un\G11714)

Checking the IP address

Checking with the buffer memory
