Device Configuration registers are user configured to contain the Company ID, Logic Application number and logic Application version. This information is then saved in a group of reserved registers in the I/O database.
  • A new DNP feature, Unsolicited Back off Time, is added to the DNP Configuration. This new feature controls a time that for retrying transmission of unsolicited messages. Whenever a DNP unsolicited message fails, including all its retries, an unsolicited back off timer is initiated. After the configured time delay has passed the unsolicited message is sent again. This process is repeated continuously until the unsolicited message is successfully sent and acknowledged.
