Network Instructions
Section 3-25
5.
The following two methods can be used to send a FINS command to a host
computer through a serial port with the host link host link while initiating
communications from the PLC, or the serial gateway function (converted
to CompoWay/F, Modbus-RTU, or Modbus-ASCII).
a) Set the destination unit address (bits 00 to 07 of C+3) to the unit ad-
dress of the CPU Unit or Serial Communications Unit/Board and set
the serial port number (bits 08 to 11 of C+2) to 1 for port 1 or 2 for port
2.
b) Set the destination unit address directly into bits 00 to 07 of C+3. In this
case, set the serial port number in bits 08 to 11 of C+2 to 0 for direct
specification.

CPU Unit ports
6.
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.
7.
The unit address indicates the Unit, as shown in the following table.
