Settings for Sending FINS Commands Section 3-4
Note It is also possible to set the serial port (No. 1 to 4) for the destination device.
Unit Addresses for
Computers Connected to
Serial Ports
The unit addresses for host computers connected to a CS/CJ/CP/NSJ serial
port (e.g., on a CPU Unit, Option Board, Serial Communications Unit, or
Serial Communications Board) are shown in the following table.
Note
A FINS command to a host computer cannot be issued from a CP1E CPU unit.
For the SEND, RECV, and CMND instructions, the CPU Unit will add the proper unit
address based on the unit address of the Unit/Board and the specified serial port. It
is not necessary to consider these addresses in the ladder-diagram program.
Unit Addresses for Serial
Ports on Serial
Communications Boards
and Units
The network address and serial port's unit address must be allocated and the routing table's local
network table must be created for Several settings are required when making network settings
(FINS command system settings) for serial communications through a serial port on a CS Series
Serial Communications Board or CS/CJ Series Serial Communications Unit. The network
address and the serial port's unit address (permanent) must be allocated and the routing table's
local network table must be created. The following diagrams show serial port's unit address.
