The relay can be programmed to communicate using the DNP Protocol through one of its ports. Refer to the Device Profile
Document on page 7–49 for details. The following setpoints configure the DNP Protocol within the relay.
• DNP PORT: Select which communications port will use the DNP protocol for communication. The 750/760 defaults to
the Modbus protocol on all ports.
• DNP POINT MAPPING: Select whether the User Map will be available through DNP. When enabled, the 120 User
Map values are included in the DNP Object 30 point list. See the Device Profile Document on page 7–49 for details.
• TRANS DELAY: Select the minimum time from when a DNP request is received and a response issued. A value of
zero causes the response to be issued as quickly as possible.
• DATA LINK CONFIRM MODE: Select the data link confirmation mode desired for responses sent by the 750/760.
When "Sometimes" is selected, data link confirmation is only requested when the response contains more than one
frame.
• DATA LINK CONFIRM TIMEOUT: Select a desired timeout. If no confirmation response is received within this time,
the 750/760 re-sends the frame if retries are still available.
• DATA LINK CONFIRM RETRIES: Select the number of retries that will be issued for a given data link frame.
• SELECT/OPERATE ARM TIMEOUT: Select the duration of the select / operate arm timer.
• WRITE TIME INTERVAL: Select the time that must elapse before the 750/760 will set the “need time” internal indica-
tion (IIN). After the time is written by a DNP master, the IIN will be set again after this time elapses. A value of zero dis-
ables this feature.
• COLD RESTART INHIBIT: When disabled, a cold restart request from a DNP master will cause the 750/760 to be
reset. Enabling this setpoint will cause the cold start request to initialize only the DNP sub-module.
When
COLD START INHIBIT is "Disabled" is selected, a cold restart request causes loss of protection until the
750/760 reset completes.
