Section 9 IEC-104 application settings
9.1 The use of the IEC-104 protocol
The IEC-104 and IEC-101 protocols share the same ASDU level messaging but
differ on the link level. IEC-104 is intended for packet-switched TCP/ IP
communication whereas IEC-101 is intended for serial communication. By using
the device, the IEC-101 slaves (for example RTUs) can be connected to a IEC-104
master (for example SCADA). The device requests an event from the IEC-101
slave locally and sends them to the IEC-104 master. This eliminates the need to
continuously poll the data remotely and therefore reduces the communication costs
on pay-per-use wireless network.
9.2 Configuring IEC-104 application settings
1. In the left pane, select Serial Port and I/O/IEC-104 Gateway (RSx) .
2. View and change settings in the view that opens.
3. Click Submit to save the settings.

Serial settings The serial settings define the properties of physical serial
communication between the device and an IEC-101 slave. The
selection between RS-232/422/485 is made with physical DIP
switches located below the RS2 serial port.
Serial port Indicates the serial port to which the settings apply. RS1, RS2
