5. Features

 Compatible with Modbus TCP Slave and Modbus RTU

Slave *1

Modbus is a communication protocol widely adopted in the industrial sector.

Controlling and collecting data from higher-level devices with Modbus master function can be conducted.

*1 To use the RS-422A/485 (multi-drop), the CPSN-COM-1PD module is required and the firmware version in the product should be

1.10 or later.

 Applicable with Windows driver software

The product supplies UDP/IP-based original protocol (F&eIT) and applications can be created with Windows driver software in the Win32

API function format (DLL).

On top of that, you can check whether software and hardware are operating properly with the diagnostic program.

 Support the virtual COM driver *2

Software virtual COM driver enables you to operate the product in the same way as PC COM port (standard COM). Applications can be

created with the OS standard Win32 API communication function.

*2 The CPSN-MCB271-1-041 requires the CPSN-COM-1PD module to support this feature.

3. Security Warning

When connecting to the network, be aware of security-related problems. See the examples of

Security measures below and set up the product properly along with the network devices.

1. Information security risks

 Unauthorized access from the outside through a network could cause the system halt, data

damage, or exposure to malware. *1

 Invaded and used as a stepping stone, a device might attack the others through networks. (a

victim becomes an assailant)

 Information might leak without realizing due to the connection to the network.

 Secondary damages such as harmful rumors, liability in damages, social credibility fall, and

opportunity loss are expected led by the troubles described above.

*1: Malware (Malicious Software) is software that brings harm to a computer system and performs

unintended operations.

2. Security measures – e.g.

 Do not keep using the default password. (Refer to the product manual for the password

setting).

 Set a strong password.

Combined with upper and lowercase letters, and numbers so that it cannot be easily

analogized by others.

 Change the password periodically.

 Disable unnecessary network services and functions.

 Restrict access to the network with network devices. *2

 Restrict ports to be released on the network with network devices. *2

 Create a closed network connection using such as dedicated network or VPN*3

*2: Inquire for setting procedure to manufacturers.

*3: VPN (Virtual Private Network) a secured network that wards off unauthorized access by

protecting the communication path with authentication and encryption.

Unfortunately, there are no perfect ways to avert unauthorized access or close a security hole

that are endlessly found day and night.

Please understand that risks are always involved with the Internet connection, and we strongly

recommend a user should constantly update information security measures.
