Note
Remember double word boundaries
When changed data is transferred and the data area contains values in double word format,
make sure that the 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 lead to the transfer of only one
word of the double word value (high or low word) because a change has occurred in only
that particular word. In this case, the missing word can lead to a data error on the receiving
partner (applies to ST7cc, not for an S7 CPU).
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.

Parameter: SendOnChange
Declaration: INPUT
Data type:
BOOL
Range of
values:
TRUE / FALSE
Default:
FALSE
Explanation: Send on change
With the setting TRUE, the block runs a change check within the acquired
data area "DataInput". The block checks whether at least one bit has
changed. If a change is detected, a transfer of the data area is started auto-
matically. You specify whether the entire area is transferred or only the
changed part with the "SendAll" parameter.
If the setting is FALSE, you need to trigger the transfer via the input parameter
"TriggerInput".
