Chapter 7. Monitoring Signals
In PLECS, a scope or display may be used to monitor signals real-time while the
simulation is running. Signals are only monitored in the control domain. Signals in the
electrical, magnetic, thermal, or mechanical domain cannot be monitored directly.
Instead, meters, such as voltmeter, MMF meter, thermometer, or torque sensor, are
used to convert the signal from the respective domain to the control domain. An
alternative to using meters is to use probes. Probes convert physical attributes of a
component or subsystem to the control domain. Many components in PLECS have
internal signals associated with them that a probe can monitor. Refer to a specific
component's documentation to learn what probe signals it includes.
