Setting sending of a limiting value when there is a change
The transmission property of the limiting values can be influenced by means of the parameter
"Transmission on change of the limiting value object" in the parameter node "Limiting value X".
"n limiting values active" is set for the measured value on the parameter page "CO2
measurement" or "humidity measurement". There is a maximum of four (n = 1…4) limiting
values available for the CO
2
measured value, and a maximum of two (n = 1…2) for the humidity
measured value.
o
Set the parameter "Transmission on change of the limiting value object" to "Yes".
The value is transmitted on a change of state from "0" to "1" or from "1" to "0".
i
The object value is sent again if the limiting value even occurs again, even if the reversed
event is is parametrized to "No telegr."
Cyclic sending of the limiting values
All limiting value objects of the sensors can transmit their state cyclically to the bus.
i
Telegrams of limiting value objects generated by the automatic transmission
("Transmission on change of the limiting value object") do not influence the cycle time for
the cyclical transmission of the limiting value objects.
i
If a combination with "no telegr." is set during activation of the limiting value, the
corresponding object value is not transmitted on change nor cyclically via the limiting value
object.
Setting cyclical transmission of a limit value
"n limiting values active" is set for the measured value on the parameter page "CO2
measurement" or "humidity measurement". There is a maximum of four (n = 1…4) limiting
values available for the CO
2
measured value, and a maximum of two (n = 1…2) for the humidity
measured value.
o
Set the parameter "Cyclical transmission of the limiting value object" to the required cycle
time.
The limiting value is sent at the set interval.
i
If the setting is "0", the limiting value is not transmitted cyclically.
