This diagram shows a solution where one PLC is coupled to
two redundant control stations via the IEC 60870-5-104 protocol. At the Profibus, ipConvPS functions as a slave and the PLC as a master, the DPV0 Profibus version is used. In control direction, IEC 60870-5-104 switching commands or set points are mapped to the Profibus DPV0 input section. In monitoring direction, digital and analog outputs are mapped to IEC 60870-5-104 information objects. How data is allocated is freely configurable. Time stamps can be added in ipConvPS. |
This diagram shows a solution where an PLC, which assumes
the role of a control station, is connected to one or several substations.
Two different serial protocols IEC 60870-5-101 and DNP 3.0 are used. The digital and analog PLC outputs are mapped to commands in the RTU direction. In the monitoring direction, the information objects from IEC 60870-5-101 and/or DNP 3.0 are mapped to digital and/or analog inputs. A similar topography was used for the IBIRITE project. |
