Range of
values:
See address range
Default: P#P 0.0 VOID 0
(null pointer)
Address
range:
P#DBxx.DBX yy.0 DWORD zz
•
xx: Data block number 1...32767
• yy: Byte number
•
zz: Number of double words 1...256 starting at byte number yy
Example:
P#DB20.DBX 100.0 DWORD 200
Remember the periods and spaces when entering the pointer!
Note that the default value (null pointer) is not permitted. A pointer with a real
address must be specified.
Explanation: Data input area
The ANY pointer addresses the data area in which the data to be acquired is
located. This data area must be within a data block and its length can vary
between 1 and 256 data double words. For information on the possible double
word formats, refer to the section "Function" above.
If the parameter assignment is incorrect (null pointer, length > 256, 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 consistency;
If a data segment to be transferred consists of a maximum of 48 bytes, data
consistency during the transfer is assured.
Parameter: SendAllBusy
Declaration: INPUT
Data type:
BOOL
Range of
values:
TRUE / FALSE
Default: FALSE
Explanation: Block being processed with "SendAll" = TRUE
This output indicates that the block is currently transferring the data specified
by "DataInput". The procedure is activated either by a remote single or gen-
eral request or by a local internal or external trigger.
If "SendAll" is set to TRUE, the transfer of all data is triggered either by inter-
nal change control (SendOnChange = TRUE) or by the external "TriggerInput"
(edge change 0 → 1).
The edge change 0 → 1 has no effect whatsoever with an external "TriggerIn-
put" as long as "SendAllBusy" indicates TRUE. The edge change 0 → 1 of
"TriggerInput" only takes effect when "SendAllBusy" = FALSE.
