The TwinCAT Power Monitoring function is a PLC library for the evaluation of raw current and voltage data, which are usually supplied by EL3773 and EL3783 EtherCAT Terminals. Function blocks are available for the calculation of RMS values for current, voltage and power. These can be output as instantaneous or average values. Maximum and minimum values are also available on the function block. Frequency and frequency spectra can be determined, such as e.g. harmonics in the grid and their load in the form of the Total Harmonic Distortion (THD).

The TwinCAT 3 Scope View is a software oscilloscope for the graphic representation of signal curves in different chart types. These could be, for example, YT, XY, bar or digital charts. The Scope View Professional extends the Scope View Base version supplied with TwinCAT 3 XAE by additional functionalities. The field of application refers to processes that are to be tracked and monitored over a longer period of time.

TwinCAT 3 Database Server enables the exchange of data between databases and the TwinCAT system. PLC variables or direct values of the EtherCAT I/Os can be logged cyclically when changes occur or event-controlled by means of PLC function blocks.

The TwinCAT 3 IoT Communicator App provides a simple solution for monitoring and analyzing TwinCAT process data on mobile end devices. In addition, widgets for lamps, fans, air conditioners and other components enable specific data from building automation to be displayed. To receive, send and display selected TwinCAT messages, apps can be downloaded from the app stores free of charge.
