bachmann: Grid Measurement in the PLC

The GM260 from Bachmann is a grid measuring module that can be directly integrated in all M1 controller systems. The GM260 supplies current and voltage measured values, frequency as well as power and power factor for up to two 3-phase branches (high-resolution in TrueRMS process), and offers 4-quadrant energy metering for each of the two three-phase systems.

The direct integration in the M1 automation system simplifies and speeds up the engineering, enabling comprehensive remote diagnostics and teleservice. The fast sampling rate in each period also enables use for operational measurement, closed-loop control as well as for condition monitoring.

The fast memory media and the wide range of communication interfaces of the M1 provide useful support especially for overall energy monitoring applications: Additional meters for gas or process heat can be supplemented via M-Bus or Modbus, external electricity meters via IEC61850 or IEC60870. A wide range of fieldbus or telecontrol protocols, OPC DA/UA as well as e-mail and FTP are provided for routing the collected energy data. The measuring intervals on several devices can be time synchronized via SNTP or the IEEE 1588 Precision Time Protocol in order to evaluate consumption values consistently.

Configuration and commissioning diagnostics are implemented in the SolutionCenter engineering tool through intuitive graphical interfaces, and offer access control with password protection in order to prevent manipulation.

Its extraordinarily compact design makes the GM260 module in conjunction with the synergy effects of direct integration an attractive solution, even for cost-sensitive applications.
