Event class 1
All changes of a process value are buffered in the event memory and
reported immediately to the master station.
Event class 2
All changes of a
process value are buffered in the event memory and
reported immediately to the master station.
Event class 3
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.
No event class
If you do not specify an event class, there is no change moni
toring of the
process values of the data object and changes are not reported to the
master station as an event (class 0 poll).
Command direction
Range of
values:
IN / OUT
Default:
•
TIM with master station function: ON (cannot be changed)
•
TIM with station / node station function: OUT
Explanation:
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 cor
responding
objects by two communicating stations (object pair). The option is enabled
for the sending object and disabled for the receiving object.
