Interrupt inputs
All digital inputs of the on-board I/O of CPUs 31xC can be used as interrupt inputs.
You can specify interrupt behavior for each individual input in your parameter declaration.
Options are:
• no interrupt
• Interrupt at the positive edge
• Interrupt at the negative edge
• Interrupt at the positive and negative edge
Note
Every channel will hold one event if the rate of incoming interrupts exceeds the handling
capacity of OB40. Further events (interrupts) will be lost, without diagnostics or explicit
message.
