This input is used to enable local input of a parameter over the data area
addressed with LocalParameterInput. Parameters sent for example by the
master are not accepted by the object as long as Local = TRUE.
The current status of the Local input is transferred to the partner.
Bumpless switchover:
• When there is a switchover from Local = 0 to Local = 1, the last values at
ParameterOutput are held until new parameter values are entered over
LocalParameterInput.
• When there is a switchback from Local = 1 to Local = 0, the last values at
ParameterOutput are held until the block receives new parameter values
from the remote partner.
Special case:
You can also enter the parameter values during local input directly in the
output area defined by ParameterOutput. Either you do not specify an input
area for LocalParameterInput or you specify the same data area both for
LocalParameterInput and ParameterOutput.
This type of the parameter entry cannot be prevented by the Local input.
Regardless of the Local status, the values entered in the output area are
sent immediately to the partner by the function block.
Local parameter entries can therefore be made regardless of the status of
the Local input. Local only influences the acceptance of parameters sent by
the remote partner:
• If Local = 0, the parameters sent by the remote partner are accepted and
output to the ParameterOutput data area.
• If Local = 1, any parameters sent by the remote partner are rejected.
In this special situation, the Release input and ContinuousEnterFunct have
no function.
A status change of the Local parameter is always sent by the TIM according
to the send buffer principle (even when the parameter ImageMemory =
TRUE). This ensures that the optional synchronization of the input and
output area on the partner is always performed correctly (see FB Par12D_S,
parameters ApplyRemoteParamMan and ApplyRemoteParamAuto).
Note
Please read the note on the ContinuousEnterFunct parameter.
