The alarm function can be used to monitor the analog inputs. If the limit value is
exceeded, multifunctional relay K6 is activated (depending on the switching
characteristic). The alarm function can have different switching functions (lk1 to lk8)
and can be set to a deviation from the active setpoint or to a fixed limit value.
In the case of alarm functions lk1 to lk6, the actual value InP1 is monitored in relation
to a limit value AL that has to be set (with the absolute value dependent on the setpoint
(w)).
