Arctic Substation Gateway
7 IEC-104 application settings
The IEC-104 and IEC-101 protocols share the same ASDU level messaging
but differ on the link level. The IEC-104 is intended for packet-switched TCP/
IP communication whereas the IEC-101 is intended for serial communication.
By using the Arctic Substation Gateway, the IEC-101 slaves (e.g. RTUs)
can be connected to a IEC-104 master (e.g. SCADA). The Arctic requests
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. This
approach also eliminates the IEC-101 parameter adjutancy problems caused
by variable round-trip delays on wireless networks and makes the information
exchange faster and more reliable.
You can view and change the application settings in Applications > IEC-104
(RSx).
