(4) When specifying the serial port without a routing table for the serial gate-
way function (conversion to host link FINS), set the serial port’s unit ad-
dress in the destination network address byte.
(5) The unit address indicates the Unit, as shown in the following table.
(6) The maximum node number depends on the network being used. For a
Controller Link, the allowed range is 00 to 20 hexadecimal (0 to 32). Set
the destination node number to FF to broadcast to all nodes; set it to 00
to transmit within the local node.
Port Port’s unit address
Port 1 FD hex (253 decimal)
Port 2 FC hex (252 decimal)
Port Port’s unit address
Port 1 FC hex (252 decimal)
Port Port’s unit address Example: Unit number = 1
Port 1 80 hex + 4 × unit number 80 + 4 × 1 = 84 hex (132 decimal)
Port 2 81 hex + 4 × unit number 81 + 4 × 1 = 85 hex (133 decimal)
