•Bitmap Set - 8-bit bitmap.
Bit 7: TCP Enable
Avalue of 0 means DNP over TCP listening point disabled.
Avalue of 1 means DNP over TCP listening point enabled.
Bit 6: UDP Enable
Avalue of 0 means DNP over UDP end point disabled.
Avalue of 1 means DNP over UDP end point enabled.
Bit 5: Validate Client Point
Avalue of 0 means No validation and any port is accepted.
Avalue of 1 means Validate connections against the first 1-4 entries.
Bit 4: UDP Response Behavior
Avalue of 0 means Respond to Client Port.
Avalue of 1 means Respond to programmed UDP respond port.
Bit 3 to Bit 0: Reserved
•UDPAddressing - 1 byte unsigned integer.
•Validate Connection Count- 1 byte unsigned integer.
•TCPListen Port - Two byte unsigned integer. TCP listening port.
•UDPListen Port - Two byte unsigned integer. UDP listening port.
•Valid IPAddress 1,2,3,4 - Four 4 byte IP address. Each byte is 1 unsigned integer. These are
IP addresses for validating TCP connections and UDP datagrams.
•Valid IPSubnet Mask 1,2,3,4 - Four 4 byte IP address. Each byte is unsigned integer. These
are IP subnet masks for validating TCP connections and UDP datagrams.
•TCPStarting Valid Client Ports - Four 2 byte unsigned integers. These are Starting Client
ports for validating TCPconnections.
