P410 Manual Mode Output; P414 Setpoint Configuration; P415 Local Set Point Value - Siemens Milltronics BW500 Operating Instructions Manual

12.7.8

P410 Manual Mode Output

Displays the percentage output value (P410-01 or -02) for the corresponding PID system (1 or
2).
When the PID system is in manual, this is the value output, providing bumpless transfer when
switching from manual to auto. When switching from auto to manual, this parameter is loaded
with the current controlled value.
12.7.9

P414 Setpoint Configuration

Configures the setpoint (P414-01 or -02) for the corresponding PID system (1 or 2).
Determines the source for the PID's setpoint. If local, the setpoint value is entered into P415.
The setpoint can be set from the mA input 1 or 2. The mA value is scaled to the full scale value
of the process value (P402).
Entry:
0 = local
1 = mA input 1
2 = mA input 2
3 = % rate
4 = % load
For PID-01, the setpoint source is mA input 1; for PID-02, the setpoint source is mA input 2.
1)
Options 3 and 4 are only available if P402 has been set for an external process value source.
2)
For option 3, the setpoint will be the current rate value displayed as a percentage: for option 4 it
will be the current load value displayed as a percentage.
12.7.10

P415 Local Set point Value

Sets the local set point (P415-01 / 02), in engineering units, for the corresponding PID system (1
or 2) when in auto mode. For the external process variable, the set point is shown in % (f =
0.000).
Note
The PID setpoint can be modified while in RUN mode using the up/down arrow keys.
