Switching
action
The logic functions are activated through logic inputs (floating contacts
(switches/relay contacts)), limit comparators, operating contacts or logic.
The functions are divided into two groups:
Edge-triggered
functions
The logic functions react to switch-on edges.
The following functions are edged-triggered:
-start/stop self-optimisation
-start profile program
-abort profile program
- profile program selection via one logic input only
-acknowledge limit comparators
State-operated
functions
The logic functions react to switch-on or switch-off states.
-all other functions
Combined
logic functions
A combination of two operating varia-
bles (logic inputs, limit comparators,
logic and operating contacts) can be
used to implement the functions set-
point/process value switching.
The profile program selection is real-
ised via three operating variables.
Any operating variable can be selected.
The states Z1 — Z2(Z3) are assigned to
the operating variables in descending
order (see list on the right).
