The IEC 60870 protocol family is a vendor-independent

communication standard for electricity industry. With Arctic IEC-

104 Gateway conventional IEC-101 devices can be attached to

a modern TCP/IP based IEC-104 control system. Ethernet and GPRS

network interfaces provide a seamless communication solution for

most of the applications. Secure (Firewall, VPN) and two-way GPRS

communication (static IP addresses) is provided with Viola M2M

Gateway or with operator APN. Finally the complete solution for

upgrading the communication system to take advantage of the

efficient and low-cost IEC-104 approach!

The IEC-101 protocol is designedfor circuit-switched data links suchas conventional PSTN modem andleased-line whereas the IEC-104takes advantage of modern packet-switched TCP/IP networks. Thefundamental difference between

these two approaches is the waythey handle event transmission.The IEC-101 protocol usessynchronous polling whereSCADA continuously sendsrequests and devices respond. InIEC-104 the devices can send

events asynchronously as theyarise while SCADA performs onlyslow-period background scans.The result is a more efficient useof network resources and fasterdelivery of data, alarms and otherevents.

Polling IEC-101 devices over thenetwork becomes unpractical andcostly on slow-speed (such asMobitex) or pay-per-use (such asGPRS) networks. Arctic IEC-104Gateway can poll the IEC-101devices locally and send the eventsto IEC-104 network only if theyarise. If there is no event availableArctic IEC-104 Gateway onlysends slow-period link test polls.Another advantage of IEC-104 isthe use of communication window.Instead of sendingacknowledgement after everypacket the IEC-104 allows multiplepackets to be acknowledgedcollectively. Arctic IEC-104

Gateway buffers every packetuntil it receives acknowledgementfrom SCADA. The packetcompressor of Arctic IEC-104Gateway can also send multipleevents in single TCP/IP packetinstead of sending themindividually.

In many applications the IEC-101field devices need to be time-synchroniced for e.g. tracking theorder of events between severalelectricity substations or feeders.Due topacket switching thenetwork delays can beunpredictable and cause evenseveral seconds of variance in timewhen synchronization is done fromSCADA.External GPS module canbe connected to Arctic IEC-104Gateway to get an exact timereference from a GPS satellite atomclock and accurately synchronizethe IEC-101 devices locally.
