With the types that have an Ethernet communication function, even if I set the Ethernet setting switch to "1," it reverts to "0."

The Ethernet setting switch is designed to enable Ethernet related parameter settings. Setting the parameter to ENTRY "1" enables the parity, IP address, subnet mask, default gateway, and port number settings. When you set this parameter to ENTRY "1", the settings are enabled, and Ethernet communication becomes possible. From that moment, the setting automatically returns to "0."
