NOTICE

Relocating a configured control to a new site, be sure to enter its new DNP address.

If the new address is not entered, the control may respond to commands intended

for a different location.

Number of Retries for Confirm

This is the number of times the control will resend a data-lled unsolicited response

to the master station if a conrmation message is not received within the Time Delay

Between Retries setting. The control will save the event data after this number of retries

until it receives a conrmation. If there is no conrmation after the number of retries

is exceeded and a new event occurs, the control will resend the saved event data along

with any new event data. Setting this parameter at 0 will prevent retries. This setting

applies to all masters. (Range: 0-10; Step: 1; Default: 6)

Time Delay Between Retries

This is the time delay between retries for initial unsolicited null and data-lled unsolicited

responses. The initial unsolicited null is transmitted indenitely until the master conrms

it. Data-lled unsolicited responses are transmitted until the number of retries specied

in the Number of Retries for Conrm setting has been reached. Transmission retries

stop when an application conrmation is received from the master during this period.

For master event requests, this is the application confirmation timeout period. When

the control receives a confirmation after this timer has expired the confirmation will

be ignored and the events will remain in the event buffers. This setting applies to all

masters. (Range 0.100-65.535 seconds; Step: 0.001; Default: 5.000)

NOTICE

When the master will set or read an Application Layer Confirmation Retry Time

longer than 32.767 seconds: To set it, use Group 41 variation 1 (32-bit); to read it,

use Group 40 variation 1 (32-bit with flag). Otherwise, a SCADA poll may report a

negative value because the default configuration is 16-bit. Please review the DNP

Points List and Implementation instruction sheet for more information.

Output Block Point Select Timeout

This is the timeout duration of the Select function on control points. See Instruction

Sheet 766-560, “IntelliRupter® PulseCloser® Fault Interrupter: DNP Points List and

Implementation.” If the timeout duration between Select and Operate functions during

a Select-Before-Operate sequence exceeds this timeout value, the control will disable

the point and return a timeout status code in the subsequent Operate request. This

setting applies to all masters. (Range: 1.0-100.0; Step: 0.1; Default: 10.0)
