The display unit uses the TCP protocol to communicate with Camera-Viewer EX.
9 + the port number defined in offline mode ([Main Unit Settings]-[Ethernet Local Settings]-[Port]) is the port number used for communication. By default, the [Ethernet Local Settings] window's [Port] field is set to 8000. As a result, port 8009 is used for communication with Camera-Viewer EX.
If this port number is used for communication with other equipment (for example device/PLC that uses TCP), Camera-Viewer EX will not operate. An error message will appear.
