Name: NewData
Refer to
Parameters you require often (Page 223).
Explanation
of the
typical-
specific
outputs
Whenever the FB has received new parameter values from the partner
object and has output them to the output field ParameterOutput, the
NewData output is set to TRUE for one OB1 cycle. This also applies when
there is new local input when Local = 1.
Name: Release
Declaration: IN_OUT
Data type BOOL
Default: FALSE
Explanation Input for the acceptance of local parameter entry.
No parameter specified: Default value FALSE is valid
Range of
values:
Input
Bit memory
Data bit
I 0.0 ... I n.7
M 0.0 ... M n.7
DBm.DBX 0.0 ... n.7
The acceptance of the parameter value at the LocalParameterInput
parameter input can be triggered over this input by a signal edge change.
A change from 0 to 1 at the Release input is taken into account only 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).
You can use this Release 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. The parameter values are read in and
checked for changes only when the Release function key is activated. The
change check is implemented by comparing the current parameter values at
ParameterOutput. Changes in the input area are then 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 Release input is reset automatically. Instead of a memory bit or data bit,
a digital input can also be specified as the input. The automatic reset would
not work with a digital input. This does not, however, have negative effects.
The triggering of the acquisition over Release is triggered by a signal edge
change; in other words, it occurs only once.
If you do not require the parameter, simply leave it open.
