IEC 61850 client, basics
The WinCC OA IEC 61850 client is a native driver designed to communicate with IEC 61850 compliant devices. The communication protocol used by the client is MMS over TCP/IP. The client is supported on Windows and Linux and can be used for:
- Retrieving data in polling mode
- Receiving data unsolicited (reporting compliant with the IEC 61850 standard)
- Writing data to a device
Information retrieved can be measurement, status, protection and control information. For writing control information to a device, command objects as defined by the standard are supported (see also entry below). The client ships with an engineering tool which allows managing and monitoring your configured devices.
According to the IEC standard control data must be written by the means of a command object. This object must be transmitted to the device as an atomic structure. See chapter IEC 61850 Control Model for further information.
Time and quality information for unsolicited transfers (reporting), as defined by the IEC 61850 standard, are only available for attributes (tags) of the data set type FCD if they are supported according to the IEC 61850 standard. See Details of the IEC 61850 client for a list of supported attributes. For all other attributes and when polling is used no quality information is available and the timestamp is using the client time, i.e. the time of the machine where the driver is running.
