• Version: 15.03.2016 • Technical changes and errors excepted.
Switching output:
Set the behaviour of the switching output when a threshold value is exceeded/undercut.
Block:
The switching output can be blocked using an object. Define specifications here for the
behaviour of the output when blocked.
The behaviour of the switching output on release is dependent on the value of the pa-
rameter "Switching output sends" (see "Switching output")
Step size
(upon increase/decrease change)
0.1°C • ... • 1°C • ... • 5°C
Hysteresis of the threshold value in %
0 … 50; 20
When the following conditions apply, the
output is
(TV = Threshold value)
• TV above = 1 | TV - Hyst. below = 0
• TV above = 0 | TV - Hyst. below = 1
• TV below = 1 | TV + Hyst. above = 0
• TV below = 0 | TV + Hyst. above = 1
Delays can be set via objects
(in seconds)
No • Yes
Switching delay from 0 to 1
none • 1 s … 2 h
Switching delay from 1 to 0
none • 1 s … 2 h
Switching output sends
• on change
• on change to 1
• on change to 0
• on change and periodically
• on change to 1 and periodically
• on change to 0 and periodically
Send cycle
(is sent only if "periodically" is selected)
5 s ... 2 h
Use switching output block
No • Yes
Analysis of the blocking object
• At value 1: block | At value 0: release
• At value 0: block | At value 1: release
Blocking object value before first call
0 • 1
Behaviour of the switching output
On block
• Do not send message
• send 0
• send 1
On release
(with 2 seconds release delay)
[Dependent on the "Switching output
sends" setting]
Switching output sends on change
• Do not send message
• Send switching output status
Switching output sends on change to 1
• Do not send message
• if switching output = 1
send 1
Switching output sends on change to 0
• Do not send message
• if switching output = 0
send 0
