Network Instructions
Section 3-25
b) Set the destination unit address directly into bits 00 to 07 of C+2. In this
case, set the serial port number in bits 08 to 11 of C+1 to 0 for direct
specification.
Serial Communication Unit ports
Serial Communication Board ports
CPU Unit ports
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.
7.
Refer to
Automatic Allocation of Communications Ports
on page 1032 for
details on using automatic allocation of the communications port number
(logical port).
8.
When the destination node number is set to FF (broadcast transmission),
there will be no response even if bits 12 to 15 are set to 0.
