Note
Fast setting of triggers
Triggers must not be set faster than a minimum interval of 500 milliseconds. This also
applies to hardware triggers (
input area).
Note
Hardware trigger
You need to reset hardware triggers via the user program
Transferring the value of a data point configured as an event
You specify whether the value of a data point is transferred to the communications partner
immediately after the trigger fires or after a delay in the "Transmission mode" parameter.
The transmission mode of a frame is set in the "Trigger" tab of the data point. With the
option, you specify whether messages of events are sent immediately or following a delay:
● Spontaneous (unsolicited - direct transfer)
The value is transferred immediately.
● Conditional spontaneous (buffered transfer)
The value is transferred only when one of the following conditions is fulfilled:
– The communications partner queries the station.
– The value of another event with the transmission mode "Spontaneous" is transferred.
– The fill level of the send buffer has reached 90% of its maximum capacity.
Allows the retentive saving of events on the SD card of the S7-1500 CPU when there are
connection disruptions.
Archiving can be enabled under the following conditions:
● The transmission mode of the data point is "Every value triggered".
● The "Enable retentive saving" option is selected in the parameter group "Basic settings >
Retentive saving of events" of the TIM.
For information on the options and mechanisms of the parameter, see section Configuration
(Page 58).
