Mainova Communication Hub

At the Mainova Gas section there is a number of substations which are to be controlled directly over the network. Twenty protocol converters, one at each station, are used as network node computer to link up the substations with the superior redundantly laid out control stations. Communication to the superior control stations is implemented with the IEC 60870-5-104 protocol.
The substations can also be controlled locally by a connected station control computer, should there be a network failure.

The protocol converter and station control computer use platform-independent OPC DA XML for communicating. The sphinx open visualization system of in-integrierte informationssysteme GmbH runs on the station control computer. Both the network node computer and the station control computer use the LINUX operating system.

Data transfer between protocol converter and substations is based on SEAB 1F, IEC 60870-5-101 and Modbus.
The SEAB 1F data of the AEG MODICON A120 substations are transmitted over AEG UEM 201 modems
