Select suitable trigger points so that the data on the TIM is not overwritten by
buffer overflow (intervals too long).
If you do not require the parameter, simply leave it open. You should, howev-
er, then set the "SendOnChange" parameter to TRUE so that the data is
transmitted automatically at every change.
For the triggering you can also select a combination of "SendOnChange" plus
"TriggerInput". This means that a transfer is triggered both when a change is
detected and at every edge change from 0 to 1 at the "TriggerInput" input.
If you use neither "SendOnChange" nor "TriggerInput" to trigger data transfer,
the data will only be transferred when there is a single request for this data
object or within the framework of a general request.
Do not transfer any analog values for which the "SendOnChange" parameter
= TRUE is set without first preprocessing the process data. You will find more
detailed information on this with the analog value typical Ana04W_S, parame-
ter "ThresholdValue".
SendAll
INPUT
BOOL
TRUE / FALSE
TRUE
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.
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.
