Precautions
No response will be returned if the command ends normally. A response will
be returned only if an error occurs.
In some cases, send requests (SEND/RECV instructions) made from the PLC
to the built-in Ethernet port just before execution of the RESET command may
not be executed.
Except for the FINS communications service sockets, all open sockets (for
sockets services) are closed immediately before resetting.
