Glossary

A
Actuator
Final controlling element, valve, signal lamps, relays, motor contactor with
positively driven contacts.
See also "Positively driven contacts, positively driven relays".
Request
Event that the PROFIsafe I/O module causes a safety function to be executed.
Request duration
Minimum duration of a signal voltage "0" (e.g., open input) on the input of the
PROFIsafe I/O module.
User acknowledgement (Operator Acknowledge (OA))
Prompt for user acknowledgement (operator acknowledge) that evokes start-up of
a machine or system. User acknowledgement is necessary for the PROFIsafe I/O
module, for example, after detecting errors by the PROFIsafe I/O module and
their resolution by maintenance personnel and is initiated from the control level.
See also "Operator Acknowledge (OA)".
Antivalence
Two different input signals, e.g., open and closed contacts on two inputs of the
PROFIsafe I/O module.
Equivalence
Two same input signals, e.g., two open contacts on two inputs of the PROFIsafe
I/O module.
Failure
Termination of the capacity of a unit to complete the required function.
See also "Dangerous failure".
Output monitoring
The PROFIsafe I/O module checks the voltage on the output signal line against an
expected value.
