Explanation: Local parameter input released
Parameter:
Declaration:
Data type:
Range of
values:
210
Release of the local parameter input of the data area specified by "LocalPa-
rameterInput".
A setpoint sent by the partner (master station) is 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 1, the last values output at
the "ParameterOutput" output are retained until new parameter values are
entered via the local input area "LocalParameterInput".
• When there is a switchback from Local = 1 to 0, the last values at the
"ParameterOutput" output are retained until the block receives new
parameter values from the partner.
Read the note on the "ContinuousEnterFunct" parameter.
Special situation:
You can also enter the parameter values during local input directly in the out-
put area specified 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 parameter input cannot be prevented by the "Local" input. Re-
gardless of the status of the "Local" parameter, the values entered in the out-
put area are sent immediately by the block to the partner.
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 partner:
• Local = 0
The parameters sent by the partner are accepted and output to the
"ParameterOutput" data area.
• Local = 1
The parameters sent by the partner are rejected.
In this special situation, the "Release" and "ContinuousEnterFunct" have no
function.
A status change of the "Local" parameter is always transferred by the module
according to the send buffer principle, even when the parameter "Image-
Memory" = TRUE. This ensures that the optional synchronization of the input
and output area on the partner is always performed correctly (see Par12D_S,
parameters "ApplyRemoteParamMan" and "ApplyRemoteParamAuto").
