*1: When re-reading the flash ROM, the re-initialization is performed in the same status as
when the power supply is turned on.
POINT
Please keep the following points in mind when re-initializing the Ethernet module.
(Failure to do so may cause errors in the data communication with the external
devices.)
(1) Be sure to end all current data communication with external devices and
close all connections before re-initializing.
(2) Be sure to reset external devices if the IP address of the Ethernet module has
been changed. (If an external device maintains the Ethernet address of a
device with which it communicates, the communication may not work after the
IP address of the Ethernet module has been changed.)
NOTE
It is possible to change the operational settings when re-initializing by a sequence
program.
