Industrial Fiber Optic Networking For Factory Automation and Process Control
Weed Instrument
Fiber Optic Products
Commercial vs. Industrial Fiber Optic Products Most process plants and factories have unique requirements for communications networks that differ from those of a commercial network. Industrial network components must withstand harsher environmental conditions such as extreme temperature ranges, lightning strikes, electromagnetic interference, and hazardous locations just to name a few.
Mounting and space requirements are also an issue since industrial networking components must be mounted in the same control panel with other control equipment. At Weed Instrument, our goal is to meet the demanding requirements of industrial communication networks. The modular EOTec brand of industrially hardened fiber optic communication products addresses these issues and provides optimal solutions for factory automation and process control.
Overview of Networking System
2
Why Fiber Optics? Fiber optics can be found in many applications, from network backbones that power the Internet to manufacturing facilit ies, to subsea communication networks on drilling rigs. The information carrying capacity of an optical fiber is far greater than it is for copper wire, coaxial cables, and microwave links. Optical fibers are very small, lightweight, do not corrode and are immune to electrical noise from lightning storms and electromagnetic interference (EMI/RFI). In addition, fiber optic cables do not carry electrical energy and are approved for hazardous locations. The cost of fiber optic cable and its associated connectors and hardware has decreased steadily over the years. Today, the benefits of fiber optics can far outweigh the costs making fiber optic communications the preferred choice for industrial factory automation and process control networks.

Network Protocols The PLC has been on the forefront of factory automation for several decades and there are many different network protocols in use today. Network protocols are either open or proprietary. Some prominent proprietary protocols supported by Weed Instrument are Rockwell Automation’s DH+, Schneider Electric’s Modbus Plus™ and GE Fanuc’s Genius® Bus. Open protocols include Ethernet TCP/IP, Profibus, ControlNet™ and DeviceNet™. Weed Instrument supports the most common protocols in use today for industrial PLC networks and Ethernet Connectivity.
Ethernet Connectivity Ethernet is being swiftly adopted by the industrial automation and control industry. Ethernet addresses many of the requirements of proprietary PLC buses, with the added advantages of widespread usage and lower costs due to high volumes. Weed Instrument is continually developing new fiber optic products to support Ethernet and other emerging industrial network protocols.

2DXX Optical Modules with 4-20mA Diagnostic Output. 2DXX optical modules provide a full diagnostic output (4-20mA). The output is internally powered and is proportional to the received optical power. The output can be monitored and processed continuously in order to insure the integrity of the fiber optic link. This is beneficial for critical applications such as subsea networking where degradation of the optical signals can be detected before a complete loss of communication occurs. An output less than 4mA indicates loss of optical signal. A pluggable screw terminal connection on the bottom front of the module provides easy access to the output signal.

The EOTec 2E50 and 2E51 Media Converters provide a high level of noise immunity and a long transmission range in industrial applications by converting the 10 BASE-T Ethernet interface to optical fibers. These devices can be operated individually as well as in modular hub stations. The supply voltage is 24VDC. In EOTec 2C50 hub stations, the supply voltage is supplied to all the connected devices via a BUS interconnection integrated in the base of the device. In stand-alone operation, the power supply is provided using plug-in screw clamp terminals. The converter has a link monitoring function, which separately indicates/monitors the operability of the cable connection and the connected devices for the RJ45 and optical fiber channels. It also automatically detects pairs of incorrectly connected receiving cables at the RJ45 connection and corrects them using the auto polarity correction function.

Industrial Ethernet Hubs and Switches
EOTec 2000 Ethernet Hubs and Switches are industrially hardened, DIN-rail mountable devices, which allow you to extend your industrial Ethernet network. The 2C50 and 2C51 10 BASE-T Ethernet hubs have four RJ45 twisted pair ports that can be made into a multi-port hub system. Up to two hubs can be cascaded together when powered via the backplane by using the EOTec 2A50 Ethernet Power Supply. A maximum of five hubs (twenty ports) can be cascaded together if powered via an external 24VDC power supply.
The 2C52 and 2C53 10/100 BASE-T Ethernet Switches have four RJ45 twisted pair ports and one BUS port. The integrated BUS port provides a connection for one additional EOTec 2000 Ethernet Switch or Switched Media Converter assisting in forming star network configurations. Ethernet switches are unmanaged and require no user configuration. The data rate is automatically negotiated and the ports will auto-sense full or half duplex operation. The switches will automatically learn the addresses of the devices connected to each port and will buffer and route messages accordingly.

By using two EOTec 2F50 Media Converters and one 2R50 Ethernet Hub configured in one modular assembly, a 10 Base-T Industrial Ethernet network can be configured in a ring providing optical redundancy and a high level of noise immunity for long distance transmissions over fiber optic cable. Connecting the optical fiber ports together to form a redundant self-healing ring allows for communications between any two nodes to be maintained even when a break in the fiber optic link occurs. Visible fault indicators, and potential-free diagnostic alarm relay outputs, are provided to locate fiber fault conditions.
External copper connections are required between modules, leaving two RJ45 ports available for connection to end devices. Power can be supplied through the backplane using the 2A50 power supply or externally through a terminal block on any one of the three modules.
