Serial Protocols
ROS™ v3.5 64 RS400
All learned addresses will be kept in the Device Address Table until they are active. They will
also be saved in non volatile memory and recovered if device reboots, so learning process does
not have to be repeated because of, for example, accidental power brakeage.
Aging timer is reset whenever message is received or sent to the specified address.
This concept makes DNP protocol configurable with the minimum number of parameters: IP
port, learning IP interface and aging timer.
2.2.3.3 Broadcast Messages DNP Broadcast Messages
Addresses 65521 through 65535 are DNP 3.0 broadcast addresses. RuggedServer supports
broadcasts sending messages with those destination addresses received from serial port to all
IP Addresses found in Device Address Table (either learned or statically configured). When
DNP broadcast message is received from IP network, it will be distributed to all ports configured
to support DNP protocol.
TIN Broadcast Messages
TIN broadcast messages can be received only from devices connected to the serial ports.
TIN Mode 1 Broadcast Messages
These messages will be sent to all TIN Address/Ports found in Dynamic Address Table.
TIN Mode 2 Broadcast Messages
These messages will be sent according the configuration: to all TIN addresses on every IP
address found in Dynamic Address Table and/or to all Wayside Data Radio IP addresses found
in Static Device Address Table.
