DNP Port 1 Port 2 and Port 3 Configuration
Number of Zeros
Number of zeros before the message.
Max Retries
Number of retries of the Physical Layer after collision detection.
Min Retry Time
Minimum time to retry of the Physical Layer after collision detection.
Max Retry Time
Maximum time to retry of the Physical Layer after collision detection.
Collision Type
Port 1:
NO
based on detection of transmitted data (monitoring all data transmitted on the
ECHO
link).
Port 2:
NO
based on detection of transmitted data (monitoring all data transmitted on the
ECHO
link.
DCD (Data Carrier Detect )
If the device prepares to transmit and finds the link busy, it waits until is no longer busy,
and then waits a backoff_time as follows:
backoff_time = Min Retry Time + random(Max Retry Time - Max Retry Time )
and transmit. If the device has a collision in transmission the device tries again ,up to a
configurable number of retries (
