Modbus TCP/IP to CC-Link Local & Intelligent Station Gateway


Прекращено: продукт больше не поставляется. More Info

ProSoft Technology's Modbus TCP/IP to CC-Link communication gateway allows Schneider Electric control platform users to integrate CC-Link Master compatible products with existing Modbus TCP/IP control networks.

The Modbus TCP/IP driver supports Schneider Electric processors as well most other devices that use Modbus TCP/IP. The driver allows Client (Master) and Server (Slave) configurations that use standard Ethernet TCP/IP connections and recognize both Modbus TCP/IP MBAP and Encapsulated Modbus message formats. An optional web interface can be ordered separately to add FTP (ftp://) support.

The CC-Link protocol driver acts as a Local or Intelligent Station, which enables easy connection to the CC-Link Master-controlled network for data transfer. Configuration options allow the gateway to occupy up to four (4) stations on the CC-Link network. Transient Messaging capability increases overall I/O data transfer capacity by more than 8,000 words. When configured as a Local Station, the gateway allows read-only viewing of the entire CC-Link Master cyclic database from all configured slave on the CC-Link network.

Особенности и преимущества

Powerful network integration

  • Communicate between dissimilar networks
  • A shared 10.000-word database exchanges information from devices on both networks
  • Allows integration of Modbus TCP/IP-based systems into a CC-Link Master-controlled network

Modbus TCP/IP

  • Client and/or Server communication configurations supported
  • Five simultaneous Server connections on TCP/IP Service Port 502 and five additional Server connections on any unreserved service port (typically TCP/IP Service Port 2000)
  •  One Client connection supports up to 100 commands to interface with processors or other Server-based devices

CC-Link Intelligent or Local Station

  • Compatible with CC-Link Version 1.10
  • Transient Message support for peer station communication adds more than 8,000 words of additional I/O data transfer capacity
  • Supports up to 4 occupied slave stations with 4 data words and 32 data bits per station
  • As a Local Station, provides a read-only list of all network slaves’ cyclic and status data
  • CC-Link Partner Association (CLPA) Certification

ProSoft Configuration Builder (PCB) provides a PC-based software configuration solution for quick and easy management of gateway configuration files, as well as viewing gateway and network diagnostics. The CC-Link Setup Guide and sample configuration provide a quick and easy example with step by step instructions on how to move data from one network to the other.


ProLinx® Communication Gateways provide connectivity for two or more dissimilar network types. The gateways, encased in sturdy extruded aluminum, are stand-alone DIN-rail-mounted solutions that provide data transfer between many of today’s most widely used industrial automation.


Modbus TCP/IP

ProSoft's Modbus TCP/IP implementation uses the gateway's shared internal memory database for data transfer. Sharing the memory database with another protocol driver allows the gateway to transfer data between Modbus TCP/IP devices and other devices on other networks.

Floating point data movement is supported, including configurable support for Enron or Daniel® floating point implementations.


Modbus Server (Slave)

The server driver accepts incoming connections on Service Port 502 for clients using the Modbus TCP/IP MBAP message format and from clients on Service Port 2000 (or other Service Ports) for clients using the Encapsulated Modbus message format.

  • Supports five independent server connections for Service Port 502
  • Supports five independent server connections for Service Port 2000
  • Supports a total Modbus TCP/IP data transfer capacity of up to 4000 registers or up to 64,000 bits in any combination
  • Modbus data types overlap in the gateway's memory database, so the same data can be read or written as bit-level or register-level data, whichever is most convenient.


Modbus Client (Master)

  • Actively reads data from and writes data to Modbus TCP/IP devices, using MBAP or Encapsulated Modbus message formats
  • Offers one client connection with up to 100 commands to talk to multiple severs


Status Data

Error codes, counters, and port status available



CC-Link (Control & Communication Link) is an open-standard communication protocol that enables easy connection to Mitsubishi and other Master controllers.

  • CC-Link is one of the dominant protocols used in Asia and is rapidly gaining acceptance worldwide.
  • The ProLinx CCLINK interface is a slave (Local Station or Intelligent Device), which can be connected to a CC-Link Master that controls data transfer.
  • The gateway is a stand-alone, DIN-rail-mounted solution that provides one CC-Link network port with TE-CON7 4P connector and an Ethernet port with RJ45 connector.
