Division into event classes
When configuring the TIM module, each process value to be transmitted to the DNP3 master
station can be defined as an event with a selectable class.
The DNP3 protocol defines object groups for events and these are listed below. The DNP3
specification also recommends assigning events according to the priority of the process
value of an event class:
● Critical events, for example process alarms are assigned to event class 1.
● Less critical events such as tolerance violations are assigned to classes 2 and 3.
You can group the events in the various classes to suit your purposes, for example based on
technological aspects.
You specify the event class for each object in TD7onTIM, refer to the section Data objects:
Partner and send parameters (Page 194).
Note
Changing the event class for node stations
The classification of events of class 2 and 3 in substations is set uniformly to class 1 in the
node station when sending
via a node station.
Note
No spontaneous sending on half duplex connections
To avoid data collisions, the TIM modules do not send any spontaneous messages on half
duplex connections.
Supported DNP3 object groups
Object groups supported by DNP3 TIM modules
The following table provides an overview of the DNP3 object groups and variations
supported by the DNP3 TIM. For both station types “station” and “master station” you will find
the suitable TD7onTIM obects.
The station type "master station" can be a TIM module in a master station or a TIM 4R IE
DNP3 in a node station.
