To change the function of a digital input, you must interconnect the status parameter of the
digital input with a binector input of your choice.
Binector inputs are designated in the parameter list with the "BI".
Example
To acknowledge converter fault messages using digital input DI1, you must interconnect DI1
with the command to acknowledge faults (p2103).
Set p2103=722.1.
