Description
Monitors the state of the inputs and detects if they are not
changing as expected within the heartbeat time.

third input to be monitored
levelD:
fourth input to be monitored

Output data type
Output 1 ... 2: 1-bit
Output description
ok:
As long as the input signals are changing, this output will
be high.
error:
This output will be high in case the input signals are not
changing within the defined heartbeat time.
Settings
InputCombination:
(Any / All) When Any is selected, the ok
output will stay high as long as at least one input signal
switches in the heartbeat time.
If "Input combination" = All, the ok output will only stay high as
long as all input signals switch within the heartbeat time.
OutputReset:
(Off / Single / Dynamic) If "Output reset" = Off,
an Err = high (and OK = low) output will stay this way until one
of the inputs switches again.
If "Output reset" = Single, Err = high (and OK = low) will
revert automatically after the "Output duration" has elapsed
and keep this state until a change in the inputs retrigger the
heartbeat timer.
If "Output reset" = Dynamic, Err = high (and OK = low) will
revert automatically after the "Output duration" has elapsed.
In this case Err and OK will not revert due to any input
switching. However, any input switching during this period will
retrigger the heartbeat time.
HeartbeatTime:
0...65535 ms Setting of the heartbeat time
within the input(s) must change.
OutputDurationTime:
0...65535 ms Setting of the time the
output signal stays high after a "no input change" condition
has been detected.
