The ANY pointer addresses the data area in which the data to be acquire
d is
located. This data area must be within a data block and its length can vary
between 1 and 12 data double words.
For information on the content and formats, refer to the section "Function"
above.
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, [Info2/3] = 11). The CPU does not change to STOP. The block is then
no longer processed, however, until the error has been corrected.
Data typical Dat12D_R
Function
Receive maximum of 12 double words with any data content.
The content of each double word may be a value in double word (DWORD, DINT, REAL)
format, it can also be a mixture of other data types which together form a double word, for
example:
● 4 bytes
● 2 words
● 2 bytes + 1 word
Dat12D_R stores the received data without further processing in the data area specified by
"DataOutput". You need to evaluate and process the received data with the user program.
Note
DB with standard access
The block has
parameters of the "ANY" type. Therefore, leave the "Optimized block access"
attribute in the properties of the DB disabled.
For a description, see section Reoccurring parameters (Page 144).
