Initially, we supplied net-line FW-40 stations for network node stations in the medium-voltage network, which were each connected to a higher-level telecontrol system by means of a VFT link using IEC 60870-5-101. FW-50 telecontrol technology was then used later.

Following a discontinued post-leased line and owing to good experiences in the electricity field, net-line FW-5 and FW-50 units have also been used since 2009 in the gas sector, a GPRS VPN encrypted DSL link to the higher-level node in the heating plant using IEC 60870-5-104 having been planned independently in the first project. The stations in the gas supply are mostly formed with net-line FW-5 and expansion modules, communication taking place via dedicated signal cables by means of VFT links or SHDSL links with IEC 60870-5-101.

In the middle of 2010, the project "Data connection of customer renewable energy feed-in sources" was put out to tender. After evaluation and a positive type test, a renewable energy system designed completely by SAE was chosen, based on a net-line FW-5 station with an expansion module and GPRS modem for communication to the control centre using IEC 60870-5-104. The customer stations are incorporated in the control centre by a net-line FW-50 node, which is serial-connected to the ABB front end using IEC 60870-5-101. Further renewable energy stations have subsequently been ordered, which are connected to the new ABB central control station in a system-identical manner.
