Attention
When stopping signal processing the process is also stopped.
This menu is designed for test and maintenance purposes only. It displays all signals of the
interface to the process. The display unit is mV. It is possible to enter setpoints in mV directly, if the
signal processing is stopped. If you leave the signals menu then signal processing is restarted.
This avoids problems concerning general 647C usage.
