The connection status of the standard maintenance communication server with network client devices can be confirmed
with special internal relays M8212 to M8214. When a connection with a client device is established, the corresponding
special internal relay is turned on. When the connection is disconnected, the corresponding special internal relay is
turned off. The IP addresses of the network client devices can be confirmed with special data registers D8350 to D8361.
