Chapter 6 Micro870 Controller Distributed Network Protocol
Number of Class1 Events
If the controller is configured not to initiate Class 1 Unsolicited Responses, this
parameter is used to limit the maximum number of events, which is generated
and logged into the event buffer for Class 1 events. In this case, value 0 disables
Class 1 event generation.
If the controller is configured to generate Unsolicited Responses, and the
number of queued Class 1 events reaches this value, an Unsolicited Response is
initiated.
The valid range is 0…10000. Default value is 10.
See DNP3 10K Event Logging
on page 119 for more information.
Hold Time after Class1 Events (x 1s)
This parameter is only for a Class 1 Unsolicited Response. The controller holds
the events during Hold Time after Class1 Events (x 1s) before initiating an
Unsolicited Response.
The valid range is 0…65535. Default value is 5.
The value of 0 indicates that responses are not delayed due to this parameter.
The parameters Number of Class1 Events and Hold Time after Class1 Events
(x 1s) are used together so that if either one of the criteria are met, an
Unsolicited Response is transmitted.
By default, the Hold time is re-triggered for each new event detected.
Number of Class2 Events
If the controller is configured not to initiate Class 2 Unsolicited Responses,
this parameter is used to limit the maximum number of events, which is
generated and logged into the event buffer for Class 2 events. In this case,
value 0 disables Class 2 event generation.
If the controller is configured to generate Unsolicited Responses, and the
number of queued Class 2 events reaches this value, an Unsolicited Response is
initiated.
The valid range is 0…10000. Default value is 10.
See DNP3 10K Event Logging
on page 119 for more information
Hold Time after Class2 Events (x 1s)
This parameter is only for a Class 2 Unsolicited Response. The controller holds
the events during Hold Time after Class2 Events (x 1s) before initiating an
Unsolicited Response.
The valid range is 0…65535. Default value is 5.
The value of 0 indicates that responses are not delayed due to this parameter.
