7.2.1 Outline
The VZ20X has two Ethernet ports.
The measured values can be acquired by a dedicated communication protocol or
Modbus/TCP. For details on data formats that can be acquired, see "7.2.6 Details of
Commands/Responses."
Ports have a hub function that allows multiple VZ20X's to be connected.
Also, on an Ethernet connection, not only can data be acquired but settings can be
made and monitoring can be performed on VZ Configurator.
Note
Stop data acquisition before changing settings. Monitoring can be carried out during
