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.
