Range of
values:
Bit memory
Data bit
No parameter specified:
Default value FALSE is valid.
M 0.0 ... M n.7
DBm.DBX 0.0 ... n.7
You can use this input parameter when the parameter is entered by
software, for example at an operator panel (OP). The Release input should
then be set using a function key on the OP. You can then enter several
parameters initially on the OP. They are only transmitted when the Release
function key is activated because the change check only begins with a 1
signal at the Release input and the data double words that have changed
since the last transmission are transmitted from the data area defined by
ParameterInput.
If you always want to transmit the entire data area defined with
ParameterInput and not only the changed parameter values, you should use
the RetransmitAll input parameter instead of Release.
The Release input is reset automatically. You should therefore only specify
memory or data inputs as the input. The automatic reset would not work with
a digital input.
Data checks:
The same safety checks are carried out as with ContinuousEnterFunct =
TRUE. Refer to the description there.
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
This is an in/out parameter (declaration IN_OUT). It is difficult to specify local bit memory
with this parameter type and this should not be used.
Name: RetransmitAll
Declaration: IN_OUT
Data type BOOL
Default: FALSE
Explanation Trigger input for transmitting (or retransmitting) the entire data area defined
by ParameterInput.
