8.12 - Selection Object
Class ID 2E
hex
Instance ID 1 (setpoint)
• Attribute 0E 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 0E
only becomes effective
once a new setpoint is
sent (attribute 0F)
• When in pressure
control (destination used =1)
writing a new setpoint is
immediately tasking the
controller to regulate to the
designated pressure
• When in position control
(destination used=2) writing a
new setpoint will directly
affect the valve position
