Modbus TCP (Modbus Ethernet) Upgrade for Digi Connect ME® Device Servers

Upgrade any Digi International's Digi Connect ME® Device Server to full native Modbus/TCP protocol support via a simple download of the ProtoCessor Modbus Serial to Ethernet Router firmware.

Benefits

• Allow other native Modbus/TCP clients such as Ethernet enabled PLCs (Programmable Logic Controllers) and SCADA Systems to communicate directly with your product
• Allow multiple Modbus/TCP Clients to connect to this Modbus/TCP Server simultaneously
• Eliminate the need for serial port redirectors on workstations
• Allow Modbus/TCP OPC Servers to communicate directly with your product
• Completely avoid timing sensitivities prevalent with serial tunneling approaches.

Features

• Modbus traffic is cached and routed though the single serial port automatically.
• The ProtoCessor Modbus Serial to Ethernet Router software is fully qualified under the "Modbus Conformance Testing Program", as tested by the Modbus/TCP Conformance Test Laboratory at the University of Michigan, the official Modbus-IDA.org compliance testing body.
• The ProtoCessor Architecture provides multiple upgrade paths to other protocols, whether they be BACnet IP, EtherNet/IP (ODVA EIP), LonWorks, Profibus or DeviceNet.

Evaluation Software and Tools Provided

• Download 36 hour MSER (Modbus Serial to Ethernet Router) evaluation firmware here
• Download 36 hour Modbus/TCP server evaluation firmware here
• Follow the download procedure to upgrade your embedded Digi Connect ME® to a fully operational 36 hour version of a fully Modbus/TCP compliant Modbus Serial to Ethernet Router.

Additional Support from ProtoCessor

If your product does not currently support Modbus RTU or Modbus ASCII you have a number of options:

• If it supports a protocol such as Metasys N2 Open then ProtoCessor may have an off-the-shelf protocol conversion solution for you already. View our other product offerings here.
• You could use the ProtoCessor IO Driver Toolkit to write a driver that would be linked with the Modbus/TCP protocol driver and downloaded to the Digi Connect ME®
• You could request us to write the driver for you.

If your product does not already have a Digi Connect ME® Device Server installed, consider designing in a ProtoCessor compliant socket for full protocol support using the full ProtoCessor range of products.

OPC Server for Windows workstation support available

Get the full Modbus/TCP protocol specification from www.modbus.org and selecting the "Modbus Standard Library" link.

The full name of the Modbus/TCP protocol is "MODBUS messaging service over TCP/IP" and comprises of Client, Server and Gateway implementations. ProtoCessors support all three of these. The protocol is sometimes referred to as "Modbus Ethernet", "Modbus over Ethernet" or "Modbus TCP".
