12.6 Modbus (slave)

Modbus is a non-proprietary communication protocol. All Modbus frames are encapsulated into Ethernet frames: it is

called Modbus over TCP/IP.

That protocol is dialog based (question-answer) : the client (master) send a command, and then the server (slave), send

back wanted data.

The DAS240-BAT/DAS220-BAT includes a Modbus TCP Slave service.

12.6.1 Setup Modbus Slave

The Modbus protocol uses ethernet network. So you have to choose the port used for that feature, and then enable the

Modbus TCP server.

Default port for Modbus TCP is 502.

It is possible to use Wifi provided a USB Wifi adapter is installed and working: for performance reasons however, the

wired USB interface should be used when using Modbus.
