All changes of a process value are buffered in the event memory and report-
ed immediately to the master station.
All changes of a process value are buffered in the event memory and report-
ed immediately to the master station.
Only the last change to a process value is buffered in the event memory. The
current, modified value is transferred to the master station when the master
station requests events of event class 3.
Event class 3 is, for example, suitable for transferring counter readings since
only the last counted value is of interest.
If you do not specify an event class, there is no change monitoring of the
process values of the data object and changes are not reported to the mas-
ter station as an event (class 0 poll).
IN / OUT
• TIM with master station function: ON (cannot be changed)
• TIM with station / node station function: OUT
The parameter specifies whether an object is sent with the master station
function or the station function of the TIM.
• "Command direction" activated: The object is sent with the master station
function of the TIM. The object is assigned a master station connection
(session).
• "Command direction" deactivated: The object is sent with the station
function of the TIM.
The parameter must be identified differently for the two corresponding ob-
jects by two communicating stations (object pair). The option is enabled for
the sending object and disabled for the receiving object.
