Overview of functions
10.5.1
Overview of input functions
The following table shows all the functions that can be associated with INPn program-
mable digital inputs. Each input can then be set so as to have an inverted function (NO/
NC), to be delayed when energised or de-energised with independent settable times.
Some functions require an additional numerical parameter, defined with the index (x)
specified by parameter P15.n.02. See menu M15 Programmable Inputs for more details.
