Pulse extension

The pulse extension extends short pulses to a minimum length. Pulses that occur while a previous pulse is being extended are ignored. Pulses can be positive or negative, i.e. jumps from 0 to 1 or from 1 to 0.

Pulse extension is located downstream of the input filter in the signal flow. Pulses shorter than the input filter time are therefore filtered out before they reach the pulse extension.

You can set the pulse extension time for each input individually in the CoE parameters 80x00:12_hex "Signal extension time".

The assignment of the CoE parameters to the connection designations can be found in the chapter Assignment of the connections.

Example 1

A short positive pulse is extended to the pulse extension time.

Example 2

A short negative pulse is extended to the pulse extension time.

Example 3

A short pulse is extended to the pulse extension time. The second pulse is within the pulse extension time and is ignored.

Example 4

A pulse that is longer than the pulse extension time is passed on unchanged.
