Software
280 System Manual, 07/2009, C79000-G8976-C222-07
Range of
values:
P#DBxx.DBX yy.0 DWORD zz
xx : Data block number 1...32767
yy : Byte number
zz : Number of double words 1...12 starting at byte number
yy
Example: P#DB20.DBX 100.0 DWORD 4
Remember the periods and spaces when entering the
pointer!
No parameter specified: Default (null pointer) is valid.
The ANY pointer defines the data area in which the parameter values to be
acquired locally are located. This data area must be within a data block and
its length can vary between 1 and 12 data double words. The length must be
identical with the length set for ParameterOutput.
The content of each double word may be a value in double word format (e.g.
DINT, REAL etc.); it can also be a mixture of other formats which together
form a double word, for example,
• 4 bytes, or
• 2 words, or
• 2 bytes plus 1 word.
If you do not require the parameter, simply leave it open.
If the parameter setting is incorrect (data area not a data block, length
greater than 12 or length different from the length set for ParameterOutput),
an error message to this effect is entered in the diagnostics buffer (event ID
B114, [Info2/3] = 11). The CPU does not change to STOP. The FB is then
no longer processed, however, until the parameter assignment error has
been corrected.
Note
Only changed data is transmitted to the partner. If the data area contains values in double
word format, the user is responsible for ensuring that these double word values are actually
located in one of the maximum 12 double words of the data area to be acquired. Distribution
over two consecutive data double words could otherwise lead to the transmission of only one
word of the double word value (high or low word) because a change has occurred in only
that particular word. The missing word could lead to problems in processing on the partner
that receives this value (applies, for example to ST7cc, but not to an S7 CPU).
