For each channel an
upper
and a
lower limit
may be defined. Here only values of the
nominal range may be preset, otherwise you receive a parameterization error. By preset-
ting 7FFFh for the upper respectively 8000h for the lower limit value the corresponding
limit is deactivated. As soon as the measuring value is beyond the limits and the limit
value monitoring is activated, a process interrupt is initialized.

So you may react to asynchronous events, there is the possibility to activate a process
interrupt. A process interrupt interrupts the linear program sequence and jumps
depending on the master system to a corresponding Interrupt routine. Here you can react
to the process interrupt accordingly.
With CANopen the process interrupt data a transferred via an emergency telegram.
Operating with CPU, PROFIBUS and PROFINET the process interrupt data were trans-
ferred via diagnostics telegram.
