Unsolicited Transmit Delay Event Count
This is the number of new events that will cause an unsolicited message to be transmitted,
provided the
Unsolicited Transmit Delay Time
setting has not been reached. Setting
this parameter to 1 results in an unsolicited message generated for every new event. This
setting applies to all masters. (Range: 1-60; Step: 1; Default: 10)
Unsolicited Transmit Delay Time
This is the maximum time (in seconds) that may elapse after a new event before an
unsolicited message is sent. During this delay, other new events may be added to the
message. If the number of events reaches the
Unsolicited Transmit Delay Event Count
setting before the delay time elapses, the unsolicited message will be sent immediately.
This setting applies to all masters. (Range: 0.1-120.0; Step: 0.1; Default: 5.0)
Unsolicited Retried Indefinitely
When enabled, the
Unsolicited Retried Indefinitely
setting allows unsolicited message
retries to be performed until a confirmation is received, and the
Number of Retries for
Confirm
setting will be ignored. Disabled is recommended for normal operation. The
Unsolicited Retried Indefinitely
setting applies to all masters.
Master Stations 1 through 6
Master Station Functionality
When the box is checked to enable master functionality, several features are provided
to the master:
• Event data are saved until the master confirms receipt of the data or it just polls the
data if the
DNP Application Layer Confirmations
setting is disabled. Each of the
masters has its own event data, so if one of the masters has retrieved and confirmed
receipt of the data, the other masters can still retrieve data they have not yet received.
Unknown/unregistered masters may still receive event data through polling, but they
will only receive data that have not yet been confirmed/received by Master 1.
• The
Unsolicited Reporting by Exception
mode for event data is available.
• The
Limit Unknown Master Functionality
setting (if enabled) does not apply to
these masters.
No master can have the same DNP address as the local device. All masters must have
unique DNP addresses. To properly clear event buffers, the port code must match the
connection type, and the proper IP address must be associated with the DNP address.
DNP Address
This is the DNP address to which the control sends all unsolicited responses. This is
also used to verify whether a master is one of the registered masters. (Range: 0-65,519;
Step: 1; Default: 0)
