MMS-Client

Numerous switching, protective, and measurement devices in the energy technology area are equipped with an Ethernet interface and offer communication in accordance with the IEC 61850 standard. Via this interface, parameters can be assigned for the devices regardless of manufacturer, the devices can be diagnosed, and actual values can be picked up through polling or received per report or GOOSE.

Through the Bachmann MMS Client, the M200 control system is capable of operating and monitoring such devices. The MMS Client behaves on the controller in a manner similar to a fieldbus driver: It supplies actual values of the peripheral devices, which are received as reports or GOOSE messages, directly to the application software. Here they are available in the process image. In the control direction, switch commands, set values, and parameters for the peripheral device can be set directly from the application program.

• Entirely software-based solution; no special additional hardware necessary. Suitable for all M200 CPU types except ME203
• It is started as a stand-alone service directly from the application software
• Allows joint operation with other protocols on the same Ethernet port and in the same network
• Configuration via SolutionCenter, no external tools necessary
• Operates devices in accordance with IEC 61850 and/or IEC 61400-25 in the same network
• Control interface for sequential programs (IEC 61131-3, C/C++) with background execution for scheduled decoupling
• Library for PLC programming in accordance with IEC 61131-3
• Header file for C/C++ programming
• Monitor for general read/write queries in the SolutionCenter
• Open interface for tools and visualization
• Data from reports and GOOSE messages are available via logical I/O modules for application programs and tools
