System Description

Ethernet is the most popular protocol used to connect office computers and peripherals today. It is increasingly finding its way into other applications, and is rapidly becoming the network of choice for higher level industrial control applications. Ethernet is primarily used to connect PLCs, computers, HMI displays and other high level components.

The term “Ethernet” actually refers to the lower level communication structure. Various different versions, or implementations, of Ethernet are available, such as EtherNet/IP™ and Modbus-TCP. It is important to note that while all of these different specifications use the same physical communication method and can operate on the same cable simultaneously, they cannot necessarily communicate with each other. For example, Modbus-TCP devices cannot communicate with EtherNet/IP devices.  This is because the messages and communication protocol have been defined differently for these systems, even though the physical electrical structure is the same. Think of it as two people who speak different languages; they speak by moving air with their mouths, but the rules of the languages are different.

Turck’s BL67 Ethernet gateways provide a convenient way to connect industrial I/O devices directly to the Ethernet system, expediting monitoring and troubleshooting for the overall control scheme.

Typical System Configuration-Basic Parts List

A typical Ethernet system consists of the following parts:

• Controller • Ethernet I/O modules • Power supply

• Switches • Ethernet cable

Ethernet I/O modules act as clients on a network. A server device is needed to retrieve data from and post data to the client.  This is analogous to an office network, where the client PC on a user’s desk may actively connect with multiple servers to  access information in different areas of the enterprise. Turck Ethernet stations are designed to be fully compatible with established Ethernet standards for industrial use.

Cordsets

Turck offers a complete line of molded Ethernet cordsets to facilitate network installation, resulting in a faster start-up and fewer wiring errors. Cables are available with stranded or solid-core conductors, with or without shielding.

Most Turck Ethernet equipment uses the 4 or 8-pin (M12) Eurofast® connector specifications. These connectors provide a tough, rugged seal, and are IP 67 rated. In some cases (mainly in the control cabinet) a traditional RJ45 Ethernet connector needs to be used. Turck provides RJ45 cordsets, as well as a variety of devices made to convert between RJ45 and Eurofast connectors. Turck cordsets for the Ethernet system are available in standard lengths. Please contact your local sales representative to order custom lengths.

Maximum Lengths Ratings

Ethernet allows different maximum cable lengths depending on the type of cable being used. An Ethernet segment may be as long as 100 m, with up to 90 m solid core cable and the remaining 10 m can be stranded patch cords.
