Configuration of Interrupt Inputs

The Processor Modules PM55x-xP and PM56x-xP provide 4 onboard interrupt inputs. For using the interrupt functionality, the channels I0…I3 have to be configured accordingly.

In the channel parameters of onboard I/O / digital inputs, the channels I0…I3 can be specified as interrupt inputs. 2 interrupt values can be chosen for each channel:

• Interrupt on rising edge
• Interrupt on falling edge

The interrupt mode can be selected in parameter Input X, fast counter of the parameters list:

• Creating an Interrupt Task
• Structure of the Interrupt Program
