 Using Input Signals
The functions of multi-function input terminals S1 to S7 can be changed
as necessary by setting constants n050 to n056. With the exception of
the value “28,” the same value cannot be set for more than one of these
constants.
The function of terminal S1 is set in constant n50. Likewise, the func-
tions of terminals S2 to S7 are set in constants n51 to n56. The follow-
ing functions can be set.
