Range of
values:
TRUE or FALSE
No parameter specified: Default value FALSE is valid.
With this parameter, you can decide whether the parameter values in the
LocalParameterInput input area should be continuously read in and changes
checked. The change check is implemented by comparing the current
parameter values at ParameterOutput. Changes in the input area are copied
immediately to the output area and transmitted to the partner. Only changed
values are sent. If there is more than one change, the block sends the data
area in which all changed parameter values are located.
The ContinuousEnterFunct = TRUE parameter setting only takes effect
when the following conditions are met:
• An input area is defined by the LocalParameterInput parameter and this
is not identical to the output area defined by ParameterOutput.
and
• There is a 1 signal at the Local input (= TRUE).
This method of local parameter acquisition is suitable when the parameter
values are entered in the LocalParameterInput area by software, but can
also be used for entering the parameters from an operator panel (OP) when
the OP has no separate function key with which to trigger acceptance. For
more detailed information and related parameters, refer to the section
Function.
If you do not require the parameter, simply leave it open.
Note
The changed data area that is transmitted consists of the first and the last double word in
which a change was detected and all words located in between, even if these have not
changed.
Example:
The area to be read is 10 double words long. In this case, changes were detected in the 2nd,
5th and 8th double words. The transmitted area is therefore from the 2nd to the 8th double
word inclusive.
Note
When ContinuousEnterFunct = TRUE, the values available at LocalparameterInput are
entered immediately and passed to ParameterOutput when the 1 signal at the Local input is
detected assuming the local input values differ from the current parameter value output at
this point in time.
