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.
If the block calculates mean values, the duration of the calculation period is
defined by the TriggerInput input. The current period is ended and a new
period begun each time a transmission is triggered by this input. The interval
between two message triggers therefore determines the duration of the
mean value calculation period.
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. Message
transmission should then be triggered based on the ThresholdValue and
ThresholdIntegration threshold parameters.
*) TriggerInput actually only triggers transmission indirectly. With a 0/1 edge
at TriggerInput, the message is put together with its current values/mean
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/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).
