Settings for Sending FINS Commands Section 3-4
3-4-3 Other FINS Command Settings
Aside from the addresses, the following data must be set.
Note 1. Unit address are fixed for Units and Boards, as well as for serial ports. For
the SEND(090), RECV(098), and CMND(490) 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.
Serial Port 1:
80 Hex + 04 Hex x unit number for Serial Communications Units, E4 Hex for
Serial Communications Boards, and FC Hex (CPU Unit’s RS-232C or se-
rial port 2 on CP1H Option Board)
Serial Port 2:
81 Hex + 04 Hex x unit number for Serial Communications Units, E5 Hex for
Serial Communications Boards, and FD Hex (CPU Units peripheral port or
serial port 1 on CP1H Option Board)
2. The gateway count is decremented one for each bridge (network) that is
passed through.

Number of retries Number of times to retry sending
the command.
0 to F Hex (0 to 15 times) Yes No
Port No. Logical communications port. CS/
CJ/CP-series CPU Units have 8
communications ports, so 8 com-
munications commands can be
executed simultaneously. To exe-
cute 9 or more commands, simul-
taneously, it is necessary to set up
exclusive control.
0 to 7 Hex Yes No
Serial port No. Specifies the number of the serial
port of the Unit with Host Link
capabilities.
0: Unit/Board
1: Serial port 1 for Serial
Communications Board/
Unit or Peripheral port for
CPU Unit
2: Serial port 2 for Serial
Communications Board/
Unit or RS-232C port for

Response moni-
tor time
Monitors the time it takes to return
a response. If a response is not

ated.
