Description: Set Point Pressure
Data type: FLOAT32
Set point pressure of the controller.
To activate the set point, the controller mode (Output PDO: Device Setup) has to be in mode 0
(automatic) or in mode 1 (Digital).
Description: Device Setup
Data type: UINT16
Selection of the controller mode and the source of the set
point.
As example if you want to switch between flow or pressure control and vis versa, with value = “1” we
would control flow, and with value =”5” we would regulate pressure
Value Description
0
Automatic set point selection
The source of set point is automatically selected, i.e.: As standard the analog set point (voltage or
current signal) is active. If a digital set point is sent (via ModBus) automatically the red-y switches
to ‘Digital mode’ and the analog set point is disabled.
1
Digital set point
Activates the digital set point via digital communication (ModBus, PROFINET)
2
Analog set point (standard setting)
Selects the analog signal as set point source.
5
Pressure controller activated
6
Back Pressure controller activated
10
Direct adjustment of the valve signal
Deactivates the automatic control mode. Sets the valve control to the value of register ‘valve
power’
20
Set point 0%
Sets the set point to 0%.
21
Set point 100%
Sets the set point to 100%.
22
Valve fully closed
Deactivates the automatic control mode. Sets the valve control to 0% (Valve fully closed).
23
Valve fully open
Deactivates the automatic control mode. Sets the valve control signal to 100% (Valve fully open).
Description: Alarms
Data type: UINT16
Indicates the alarm messages in a bit map. The bit pattern depends on the status of the instrument and
the detected alarms. If an alarm condition is no longer valid the corresponding bit is automatically erased.
Value Description
0
Indicates a negative flow ( flow value < 0 )
1
Indicates a negative flow exceeding the backflow setpoint. The bit remains set until a positive flow
is detected.
2..14
Not used
15
Indicates a hardware error (register HW Status). This bit is therefore an OR-function of all
hardware errors.
