Description

Class 3 Unsol Resp Min:

1 to 255
events

Minimum number of events in Class 3
required before an unsolicited response will
be generated.

Unsol Resp Delay:

0 to 65535
milliseconds

Maximum number of 1 millisecond intervals to
wait after an event occurs before sending an
unsolicited response message. If set to 0,
only use minimum number of events.

Uresp Master Address:

0 to 65534

DNP destination address where unsolicited
response messages are sent.

Uresp Retry Count:

0 to 255
retries

Determines the number of unsolicited
message retries sent on primary DNP port
before changing to secondary port. If the
value is 0, port switching will be disabled.

AI Events with time:

Yes or No

This parameter sets if the analog input events
generated by the module will include the date
and time of the event. If the parameter is set
to No, the default is set to no time data. If the
parameter is set to Yes, the default object will
include the time of the event.

Time Sync Before
Events:

Yes or No

This parameter determines if events are to be
generated by the module before the time
synchronization from the master unit. If the
parameter is set to No, no events will be
generated until the module's time has been
synchronized. If the parameter is set to Yes,
events will always be generated.

Initialize DNP Database:

Y or N

This parameter determines if the module will
request data from the processor to initialize
the DNP database output data areas. If this
option is utilized, ladder logic is required to
send the requested block from the processor
to the module.

[DNP Slave Database]

DNP Slave Database definition

Binary Inputs:

0 to 15360
points

Number of digital input points to configure in
the DNP slave device. Each point will be
stored as a single bit in the module memory.

PLC Binary Inputs:

0 to 15360
points

Number of digital input points configured
above that are to be obtained from the PLC
processor. All other binary input points must
come from the attached IED units.

Analog Inputs:

0 to 960 pointsNumber of analog input points to configure in

the DNP slave device. Each point will occupy
a one word area in the module memory.

PLC Analog Inputs:

0 to 960 pointsNumber of analog input points configured

above that are to be obtained from the PLC
processor. All other analog input points must
come from the attached IED units.
