DNV GL (formerly KEMA) has granted Gillam-FEi an IEC60870-5-104 Attestation of Conformity for our GRTU-6K Remote Terminal Unit.
GILLAM-FEi, Belgium, manufactures digital equipments that can be used in substations. GILLAM-FEi has implemented the IEC 60870-5 Telecontrol Companion Standard 104 in the GRTU 6K product for communication with a controlling system. The IEC 60870-5 Telecontrol Companion Standard 104 (TCS104) can be used as a communication protocol for exchanging information between Control Center(s) (controlling station) and their substations (controlled stations). The information exchanged can be for example measurands, status messages and commands.
The IEC60870-5-104 (IEC104) protocol is a derivative of IEC101 which is dedicated for serial links. Application layer (i.e. datagrams) of IEC 104 is preserved same as that of IEC 101 with some of the data types and facilities not used. The IEC104 contains changes in transport, network, link & physical layer services to provide LAN / WAN connectivity and allows the use of standard network communication material (GPRS, 3G, xDSL, fiber optics, …)
