Contents of FINS header
• Destination network address(DNA)
a) When the routing table for network control of serial communication
channel is developed:
It is the network address that corresponds to serial communication
port according to the routing table.
b) When the routing table for networking serial communication channel is
not developed:
It is the network address when actual destination PLC is specified.
• Destination node address (DA1)
a) When the routing table for network control of serial communication
channel is developed:
00Hex (means PLC internal communication)
b) When the routing table for network control of serial communication
channel is not developed:
It is the node address when actual destination PLC is specified.
• Destination model address (DA2)
It needs to be the model address of serial communication port.
