1oo1 evaluation
Type of -> sensor evaluation – 1oo1 evaluation is a type of sensor evaluation in which a non-
redundant -> sensor is connected to the F-module via one channel.
1oo1 Evaluation
-> 1oo1 Evaluation
1oo2 evaluation
Type of -> sensor evaluation – In 1oo2 evaluation, two input channels are occupied, either
by one two-channel sensor or two one-channel sensors. The input signals are compared
internally for equivalence or nonequivalence.
1oo2 Evaluation
-> 1oo2 Evaluation
Acknowledgment Time
During the acknowledgment time, the -> F-I/O acknowledges the sign of life specified by the
-> F-CPU. The acknowledgment time enters into the calculation of the -> monitoring time
and -> response time for the F-system as a whole.
Actuator
Actuators can be power relays or contactors for switching on loads, or they can be loads
themselves (e.g., directly controlled solenoid valves).
Assigning Parameters
Parameter assignment via PROFIBUS DP: Transfers slave parameters from the DP master
to the DP slave.
Parameter assignment of modules/submodules: Sets the behavior of modules/submodules
with the
STEP 7 configuration software.
