None
In addition to cyclic cleaning, you can also use
an input signal to start event-controlled
cleaning.
‣
Choose the trigger for such a cleaning
process here.
Interval and weekly programs are executed as
normal, i. e. conflicts can occur. Priority is given
to the cleaning program that was the first to be
started.

‣
Decide whether there should be a hold
during the cleaning process. This hold
affects the inputs to which this cleaning
process is assigned.

10.8.5 Mathematical functions
In addition to "real" process values, which are provided by connected physical sensors or analog
inputs, mathematical functions can be used to calculate a maximum of 8 "virtual" process
values.
The "virtual" process values can be:
• Output via a current output or a fieldbus
• Used as a controlled variable
• Assigned as a measured variable to a limit switch
• Used as a measured variable to trigger cleaning
• Displayed in user-defined measuring menus
Difference
You can subtract the measured values of two sensors and use the result to detect incorrect
measurements, for example.
