Ethernet/IP to AB's DH+

DL7000-ETH-DH+
: Ethernet/IP to AB's DH+ & DH-485 using CIP & 222 Protocols.

The DL7000 is a gateway that interfaces any newer AB Ethernet/IP & AB Ethernet PLCs (ie. SLC 5/05, Compactlogix, Micrologix or PLC-5E) or MMI/SCADA/Programming package to any device/node on AB’s DH+.

This is a great low cost alternative to the Controllogix Gateway (1756-DHRIO & 1756-ENBT).

DL3500 - USB Interface to AB's DH485 or DH+ Network
The DataLink DL3500 is a RS232, RS422, RS485 serial DF1, ASCII or Modbus protocol converter to AB's DH-485 or DH+ Networks. Interfaces RSLINX/RSLOGIX to the Contrologix Gateway, Micrologix 1500, PLC5, PLC3, PLC2 & SLC 5/04; low cost replacement to the 1770-KF3, 1770-KF2 or 1784-PCMK Card.

The DL3500's USB port, size, portability, and the choice between a freestanding and DIN rail model make it especially convenient for use in the office, the plant floor, or when travelling.

Ethernet/IP Background

EtherNet/IP (Ethernet Industrial Protocol) is an open communications protocol developed by Rockwell Automation, managed by ODVA and designed for use in process control and other industrial automation applications. EtherNet/IP can be easily confused as a combination of Ethernet (the physical layer, link, or medium used in most office and many industrial networking environments) and the Internet Protocol, the world’s most ubiquitous (internet) networking protocol and part of the TCP/IP model, comprising a suite of protocols operating at the link, internet (or networking), transport, and application layers.

By comparison, EtherNet/IP is an industrial application layer protocol operating over the Ethernet medium and used for communication between industrial control systems and their components, such as a programmable automation controller, programmable logic controller or an I/O system. Furthermore, the “IP” in EtherNet/IP, is not an abbreviation for “Internet Protocol” but instead stands for “Industrial Protocol”, referring to Rockwell’s adoption of Common Industrial Protocol (CIP) standards as EtherNet/IP was developed.

Confusing matters further is the fact that when using the OSI Reference Model, EtherNet/IP, at the application layer, operates over both Ethernet (at the physical layer) and IP (at the network layer) and thus complements each of these technologies.

History
EtherNet/IP was developed in the late 1990’s by Rockwell Automation as part of Rockwell’s industrial Ethernet networking solutions. With little or no input taken from other ODVA members, Rockwell gave EtherNet/IP its moniker and handed it over to ODVA, which now manages the protocol and assures multivendor system interoperability by requiring adherence to established standards whenever new products that utilize the protocol are developed.

Today, EtherNet/IP is most commonly used in industrial automation settings (e.g., water processing plants, manufacturing facilities, utilities) in the US and Asia for communication to and from Rockwell Automation’s Allen-Bradley-brand control systems. However, other industrial automation and control system vendors, including Opto 22 and WAGO Corporation, have developed programmable automation controllers and I/O capable of communicating via EtherNet/IP.

Schneider-Electric developed an EtherNet/IP cards for both PLC Quantum and Premium on the Unity Platform.

EtherNet/IP classifies Ethernet nodes as predefined device types with specific behaviors. Among other things, this enables:
- Transfer of basic I/O data via UDP-based implicit messaging
- Uploading and downloading of parameters, setpoints, programs and recipes via TCP (i.e., explicit messaging.)
- Polled, cyclic and change-of-state monitoring via UDP, such as RPI and COS in Allen Bradley's ControlLogix control systems.
- One-to-one (unicast), one-to-many (multicast), and one-to-all (broadcast) communication via TCP.
