Description of the
threshold value function

Planning and application

How does the threshold value function?

Fig. 27: Threshold value function

In the example diagram above, it can be seen that the measured value
begins with a zero value and the communication object for the threshold
value 1 has the value „0“. This value can be cyclically sent onto the bus
if the relevant parameter in the application program is set.

As long as the measured value

does not

exceed the upper limit of the thres-

hold value 1, the communication object threshold value 1 will remain „0“.

As soon as the measured value exceeds the upper limit of the threshold
value 1, the communication object threshold will change value to „1“.

The communication object threshold value 1 will remain „1“, until the
measured value once again falls below the lower limit of the threshold value 1.
