Default:
TRUE
Explanation: Send all data with every transfer
With the parameter, you specify whether the block will always transfer all data
of the area specified with "DataInput" or only changed data. The transfer can
be triggered by the activated change check (SendOnChange = TRUE) or by
"TriggerInput".
•
SendAll = TRUE
Always send all data
•
SendAll = FALSE
Send only changed data
Exception:
If "SendAll" is set to = FALSE, the transfer is triggered by "TriggerInput"
and if no data has changed at this time, the complete area will be
transferred. For this exception this corresponds to "SendAll" = TRUE.
When only the changed data area is transferred ("SendAll" = FALSE), this
area consists of the first and the last double word in which a change was
detected and all words located in between, even if these have not
changed.
If there is a single request for this data object or within the framework of a
general request, all data words of the area specified by "DataInput" are always
transferred.
