8. 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 IEC-104 gateway the IEC-101 slaves (e.g.
RTUs) can be connected to a IEC-104 master (e.g. SCADA). The Arctic requests events 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 GPRS network.
This approach also eliminates the IEC-101 parameter adjustance problems caused by variable round-
trip delays on GPRS networks and makes the information exchange faster and more reliable.
