If required, this parameter can be used to specify an input over which the
user can trigger the transmission *) of the data message at any time (signal
edge from 0 to 1).
Example:
Time-driven analog value transmission with time stamp for supplying an
analog value archive in the control center. Note: To prevent these messages
with time stamps from being overwritten when saving on the station TIM, the
ImageMemory parameter must be set to FALSE.
FC Trigger can be used for time-driven triggering of a transmission over
TriggerInput (for more detailed information, refer to the description of this
block).
If you do not require the parameter, simply leave it open. You should,
however, then set the SendOnChange parameter to TRUE so that the data
is transmitted automatically at every change.
*) TriggerInput actually only triggers transmission indirectly. With a 0/1 edge
at TriggerInput, the message is put together with its current values and
transferred to the local TIM. The TIM is responsible for the actual
transmission to the partner. Transmission is immediate over a dedicated line
or wireless link; with a dial-up connection, it is possible that the message is
saved first on the TIM and sent at a later point in time (for example, because
the message is marked as a "conditional spontaneous" message; see the
Conditional parameter).
Note
You can also select a combination of SendOnChange plus TriggerInput. This means that a
transmission is triggered both when a change is detected and at every signal edge change
from 0 to 1 at the TriggerInput.
Note
If you use neither SendOnChange nor TriggerInput to trigger data transmission, the data will
only be transmitted when there is a single request for this data object or within the framework
of a general request.
