standard signal
This function can be used for operating control valves (e.g. motor valve, positioner) via the analog output using
the control for 4-20mA or alternatively 0-10V standard signal.
Example of a typical use, the flow-rate control in conjunction with a flow-rate sensor and an electric motor control
valve, see Figure 37.
