Rotary Encoders feature PROFINET IO support.
February 4, 2009 -
Equipped with Ertec200-based platform, OPTOCODE models support RT (real-time) and NRT (non-real-time) data transfer according to PROFIDrive profile - with cycle times as short as 10 ms. Users can assign IP addresses via control system according to ARP during start-up, and products are parameterized via control system. Using opto-electronic scanning method to record position values, single- and multi-turn sensors provide resolution of 16 and 30 bits per revolution, respectively.

New OPTOCODE Rotary Encoders with PROFINET IO Support
Hamilton, New Jersey, January 2009 - FRABA's POSITAL business unit has expanded its proven OPTOCODE family of rotary encoders for PROFINET IO networks, equipping them with a new, Ertec200-based platform. The new mod-els support RT (real-time) and NRT (non-real-time) data transfer according to the PROFIDrive profile with cycle times as short as 10 ms. IRT (isochronous real-time) models with cycle times as low as 1 ms will be available shortly for high-speed applications. These encoders now allow users to assign IP addresses via the control system according to ARP (Address Resolution Protocol) during start-up. The units are parameterized via the control system; the use of a GSDML device file enables easy configuration. The identification request is displayed by means of flashing LEDs. A bootloader enables the installation of firmware updates via FTP.
Like all OPTOCODE encoders, the PROFINET IO models use a proven opto-electronic scanning method to record position values. The single-turn sensor provides a resolution of 16 bit per revolution (65,536 steps per turn). In addition, a maximum of 16,384 revolutions (14 bit) can be registered in multi-turn mode, for a total measurement range of 30 bits. The encoders are suitable for use in automotive manufacture, packaging technology or standard machine construction applications. Migration of existing Profibus systems to the new standard is easily possible, since PROFINET uses the established device profiles. An integrated switch facilitates wiring. Further equipment options include two M12 connections for data transfer, one M12 connection for voltage supply, and LEDs for bus diagnosis. Designed for a -40 to +85 įC (-40 to 185oF) temperature range, the units are IP65 protected (up to IP66 at the flange). All OPTOCODE encoders operate without backup batteries and instantly provide current absolute position values even after power failure.
FRABA Inc. is the North American sister company of POSITAL GmbH, a highly specialized manufacturer of absolute rotary encoders and inclinometers based in Cologne, Germany. The company belongs to the FRABA Group which dates back to 1918, when its predecessor, Franz Baumgartner elektrische Apparate GmbH, was established to manufacture relays. Today, the group consists of six independent companies that develop and produce advanced industrial sensor technology and safety equipment.
