specified output channel.
Several sending channels can be set while only 1 receiving channel can be set.
Example: Sending data to OUT12 and receiving the response from OUT12
①
@SCT,1,1,0,0
Setting RS-232C communication as follows:
baud rate: 9600bps; data bit length: 8 bit; parity check: None; stop bit: 1 bit
②

Setting RS-232C transmission sending channel, specifying OUT12
③
@S+R,12
Setting RS-232C transmission receiving, specifying OUT12
④

2.2 LAN communication
2.2.1 LAN connector specification
Pin assignment of the LAN connector is as follows.
Since Auto MDI/MDI-X that distinguishes and switches straight/cross cables automatically is supported, extra
care is not necessary to connect the FDX-S to PC, HUB or the like.
Light in green while link is established.
Blinks in green while data is being
sent/received.
Light in amber if the send/receive
rate is 100 Mbps.
Goes off if it is 10 Mbps.

2.2.3 Setting up LAN communication
(1)Connect the FDX-S and the control device via a LAN cable.
(2)Set up LAN communication as follows:
・Set IP address and subnet mask
・TCP pot number: 1100, 6000 to 6999
【Reference: User guide】
(3)Establish the connection from the control device to the IP address and TCP port that are set to the FDX-S
in step (2) above.
(4)Send a communication command from the control device to the FDX-S in order to check the control status
of the FDX-S.

2.2.4 The number of TCP-IP connections
The FDX-S supports up to eight simultaneous TCP-IP connections (eight logical ports).
To maintain optimal system accessibility, it is advisable to issue “port-open” and “port-close” commands
before and after command or query strings are issued. This approach enables eight or more control devices
to be effectively interfaced simultaneously and without concern for communication errors.

Note:
As a safeguard, the FDX-S incorporates a 30-second timeout window for each port. If any port is inactive for
more than 30 seconds, it will be closed automatically.

FDX-S Series Command Guide
12
2.3 Unsolicited status notification
The FDX-S can notify status changes and problems in a system through RS-232C or LAN communication.
Unsolicited status notification:
(1)The unsolicited status notification feature is enabled using @SPH command.
(2)The control device periodically sends @GIV command (30 seconds or shorter) to keep the connection.
This step can be skipped for RS0232C communication.
(3)The FDX-S notifies control device of changes in FDX-S.
(4)The control device sends @AIN command that is for getting input status.
(5)The FDX-S sends the control device current status.

A command consists of “@” (“40” in hexadecimal), 3 one-byte alphabetical characters (upper and lower
cases), and parameters (one-byte numbers). For some commands, multiple parameter values can be
specified or parameters are not necessary.
“,”( a comma, “2C” in hex) is indicated between a command and parameter and between two parameters.
“ ” is indicated as a delimiter CR LF (return+line feed, “0D” and “0A” in hex).
Processing is executed by sending a delimiter at the end of the command.
Example:@SPM,2
■If there is an error:
An error command is returned if an undefined command or wrong parameter is included.
Example:@SOT,2
@ERR,1
■Using as HELP
If only delimiter is sent, command list as the help command is returned.
