Presetting position feedback for blind, shutter, awning or venting louver positions
The feedback functions can be enabled and programmed independently for each output.
When feedback is enabled, the ETS adapts the parameter texts depending on the preset operating mode
("Blind position feedback", "Shutter/awning position feedback" or "Venting louver position feedback"). The
status feedback can be used as an active signalling object or as a passive status object. As an active
signalling object, the position feedback information is transmitted to the bus whenever a position value
changes. As a passive status object, there is no telegram transmission after a change. In this case, the
object value must be read out. The ETS automatically sets the object communication flags required for
proper functioning.
In case of an actively transmitting signalling object, the current position can be transmitted to the bus after
bus voltage return, if the position value differs from the one last transmitted. When the position data are
known, the feedback telegram can in this case be transmitted with a time delay to reduce the bus load, with
the delay being preset globally for all outputs in common (cf. "Delay after bus voltage return").
The feedback functions of an output must be enabled on parameter page "Ax – Enabled functions" (x =
number of output). Only then are the parameters for the feedback functions visible.
Set the parameter "Blind position feedback", "Shutter/awning position feedback" or "Venting louver
position feedback" on parameter page "Ax – Feedbacks" to "feedback object is active signalling object"
The feedback object is enabled. The position value is transmitted as soon as it changes. No value will be
actively transmitted, if the position is unknown.
Set the parameter "Blind position feedback", "Shutter/awning position feedback" or "Venting louver
position feedback" on parameter page "Ax – Feedbacks" to "feedback object is passive status object"
The feedback object is enabled. The position value will be transmitted in response only if the feedback
object is read out from by the bus. If the position is unknown, a value of "0" will be reported back after
readout.
The feedback function must be preset as actively transmitting function.
If a time delay after bus voltage return should be necessary, the parameter "Time delay for feedback
after bus voltage return" on parameter page "Ax – Feedbacks" must be set to "yes"
The position is then reported back with a time delay after bus voltage return. After the end of the time
delay, the position last adjusted statically will be transmitted to the bus. No feedback telegram will be
transmitted during a running delay, even if a position value changes during this delay.
