Parameter: ContinuousEnterFunct
Declaration: INPUT
Data type:
BOOL
Range of
values:
TRUE / FALSE
Default:
FALSE
Explanation: Continuous change check
With this parameter, you can decide whether the parameter values at the "Pa-
rameterInput" input should be continuously read in and checked for changes.
The change check is made by comparison with the last values that were trans-
ferred. Only changed values are sent. If more than one change is detected,
the block sends the data area in which all changed parameter values are lo-
cated.
The changed data area that is transferred consists of the first and the last
double word in which a change was detected and all words located in be-
tween, even if these have not changed.
A new transfer of the parameter values can be triggered via the "Retrans-
mitAll" input (see below) even when the parameter entries have not changed.
This method of transmission triggering is suitable when the parameter values
are entered in the ParameterInput area by software, but can also be used for
entering the parameters from an operator panel (OP).
For further information refer to the section "Function" above.
If you do not require the parameter, simply leave it open.
Data checks:
The parameters read in are only transmitted if no error is detected during the
1-out-of-n check.
•
While for hardware input (see EnterInput) an empty cycle must be detected
before new parameter values can be transferred from the block.
•
For software input new parameter values can be transferred in every OB1
cycle. This assumes that there is no other software entry by another block
pending in this cycle. Otherwise a 1-out-of-n error is detected.
When a 1-out-of-n error is detected during the software input, the entered
parameters are no longer processed. The FB enters the detected 1-out-of-
n error in the diagnostic buffer (event ID B172).
New parameters are read in again only when previously for the length of
an OB1 cycle in the CPU, no software input via a command, setpoint or
parameter block was detected.
