TelePACE DNP ISaGRAF TCP
When there are no longer ports configured for DNP the DNP configuration can be deleted to reclaim memory. In order to change the DNP in TCP port number DNP in TCP must be disabled and then re-enabled. If no other ports were configured for DNP then the DNP configuration will be disabled when the configuration change is made. In order to prevent this a second port should be configured for DNP.
