2.1.3 Setting up LAN communication
(1) Connect the DFS 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
DFS in step (2) above.
(4) Send a communication command from the control device to the DFS in order to check the control
status of the DFS.

2.1.4 The number of TCP-IP connections
The DFS 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 DFS incorporates a 30-second timeout window for each port. If any port is inactive for
more than 30 seconds, it will be closed automatically.

3 Command
3.1 Command outline
A command consists of “@” (“40” in hexadecimal), 3 one-byte alphabetical characters (upper and lower
cases), and parameters (one-byte numbers*). For some commands, several parameters can be specified or
no parameter is required. Processing is executed by sending a delimiter at the end of the command.
Example:@SPM,2
“,” (a comma, “2C” in hexadecimal) is indicated between a command and parameter and between two
parameters.
■If there is an error:
An error command is returned if an undefined command or wrong parameter is included.
Example:@SOT,1
@ERR,1
■Using as HELP
If only delimiter is sent, command list as the help command is returned.
