What communication protocol is being converted?ĬontrolNet® (view all ControlNet products).For example, the 2C02 is the model which is compatible with GE Fanuc networks. It is important to select the correct EIM for the copper protocol being converted. The EIM also accepts signals from the backplane and transmits the signals to the attached copper link. The module receives signals from the copper link, conditions them and makes the signals available to the backplane for conversion. The Electrical Interface Module (EIM) is connected to the copper communication link.

Provides Fault Tolerant, Multidrop, and Fiber Instrument offers the worlds largest selection Three decades of experience in fiber optic networking Of Fiber Optic Networking Equipment for IndustrialĪutomation & Process Control applications. Instrument is the worlds leading manufacturer At a very minimum, every fiber optic node will require a power supply module (PSM), electrical interface module (EIM) and optical interface module (OIM). Modules with internal termination must be used at the end of copper segments only.Ĭonstructing fiber optic communication nodes is very easy if the user keeps a few simple guidelines in mind. Modules without internal termination can be used anywhere along a copper segment. Pay attention to the terminations on the electrical interface modules.The default setting for the optical transmit power is “H” (high) this setting should not be adjusted unless an optical overdrive situation occurs.The electrical interface module must be set to “1” and the adjacent modules must be set to “2” and “3”. When employing a self-healing ring configuration, the self-healing ring module is hardwired as Master.Numerical addresses cannot be repeated in a single cluster. Any additional modules sharing a common backplane with the Master must be set to a numerical address (1, 2, 3 or 4). Each cluster must have one (and only one) module set to Master (M).Each cluster can have a maximum of five communication modules (power supplies not included).The EOTec system allows the user to build a fiber optic system that supports several network topologies, including: Inter-module communications and power distribution is handled by the internal EOTec 2000 BUS architecture to minimize external wiring.Įach node can support up to five (5) EIMs or OIMs to suite the application. These configurations are easily achievable with the EOTec 2000. For instance, star and self-healing ring topologies are impossible when using copper interconnects. Fiber optic communication links can also be extended over much greater distances and take on physical topologies not available with copper networks. Problems such as ground loops, isolation and lightning strikes are eliminated with the EOTec 2000 fiber optic modems. Options are available to support all the popular fiber optic connectors (ST, SMA, SC), providing users the ability to construct dependable and robust networks. Both multi-mode and single-mode fiber optic links are supported. The EOTec 2000 series represents an extremely flexible and scalable solution to the problems often encountered when using copper to interconnect communication nodes. Simply attach each module to the DIN rail and slide them together until they mate to one another. As a result, there is no separate backplane to purchase and no external wiring between modules. All modules fit on standard 35mm DIN rail and each has an integrated backplane. The EOTec 2000 Fiber optic modems are a family of modules designed to take traditional copper networks, convert them to fiber optic signals, and convert them back again. Recently, NSPI introduced the EOTec 2104 Ethernet Ring Switch which provides an economical solution to the combination of high performance ring redundancy with Ethernet communications. ![]() In addition, we pioneered the development of Self-Healing Ring technology which provides high reliability, media redundant PLC/DCS communications (Patent #6,307,652). NSPI was the first company to receive Factory Mutual (FM) hazardous area certification for fiber optic modems. Over the years NSPI has continued to invest in the development of these products by adding new protocols, features and capabilities. The industrial fiber optic networking product line of NSPI was established through the acquisitions of Apec Electronics in 1991 and the EOTec business of the 3M Company in 1994. ![]()
