Logical input signals
To be able to map internal dependencies in the logic, selected system states are made
available as logical input signals.

Special function blocks
An active system fault can be acknowledged by means of the special "fault
acknowledgement" function block. The acknowledgement is triggered after the input signal
has been active for at least 5 s.
The controller's emergency power mode can be activated by means of the special
"emergency power mode" function block. You will find further details of the emergency power
mode in Section Emergency power mode (Page 74).
6.2.43.5
Discrepancy analysis block
The discrepancy analysis block "AND0" has four time-monitored inputs, two of which are
negated or inverted. The output signal at Q17 behaves according to the following rules:
● The output signal only becomes active if all inputs were activated synchronously within
the time defined via parameter p4610.
● The output signal becomes inactive as soon as at least one input signal has become
inactive.
● The output signal can only be reactivated after all input signals have been inactive.
6.2.43.6
Basic blocks
The basic function blocks "AND", "OR", "NOT" and "XOR" are provided to be able to map
basic logical combinations.
