• Attribute 5 determines
the selection between
pressure control or valve
control (1 for pressure
control, 2 for position
control), default is 1
after reset.
• A change on attribute 5
only becomes effective
once a new setpoint is
sent (attribute 9)
• When in pressure
control (destinationindex =1)
writing a new setpoint is immediately
tasking the controller to regulate to the designated pressure
• When in position control (destination index=2) writing
a new setpoint will directly affect the valve position
Instance ID 2 (control signal)
NOTE: This object is static. The
only changing variable is the value
of attribute 4 that is linked to
instance 1 attribute 5.
