The ANY pointer addresses the data area in which the locally entered p
a-
eter values or those received from the partner are output. This data area
must be within a data block and its length can vary between 1 and 12 double
words.
For information on the content and formats, refer to the section "Function"
above.
Par12D saves the received data without fu
rther processing in the data area
specified by "ParameterOutput". You need to evaluate and process the r
e-
ceived data with the user program.
When only changed data is sent by the partner object Par12D_S, it is possible
that only part of the data output area
is newly written. this is the area in which
the changes were detected at the acquisition end
If the parameter assignment is incorrect (null pointer, length > 12, data area
not a DB), an error message is entered in the diagnostics buffer (event ID
B114, [I
nfo2/3] = 11). The CPU does not change to STOP. The block is then
no longer processed, however, until the error has been corrected.
For the declaration, data type, range of values, default and function, refer to
the sect
ion Reoccurring parameters (Page 144).
Whenever the block has received new parameter values from the partner o
b-
ject 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 in the status "Local" = 1.
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.
