Open-Source Sercos III Master Library Launched

Sercos has announced that an open-source software driver library for the Sercos III real-time Ethernet communication system master implementation is now available via the sourceforge.net web portal. The software can be utilised according to the LGPL licence, without any licence fees and without any usage limitations. Two versions of the open-source driver for Sercos III boards are now available: a driver for plug-in cards with a dedicated central-processing unit (active boards such as the Sercans III board); and a driver for plug-in cards without a central-processing unit (passive boards).

Peter Lutz, managing director of Sercos International, said: 'It is now much easier for manufacturers to develop a Sercos III master and to benefit from future improvements and extensions of the software. 'The library is a fully tested software without any functional limitations. 'All features of Sercos III are supported, such as the real-time channel, the redundancy concept and hot plugging,' he added.

By April 2010, the driver will be integrated into the mainline version of the Linux open-source operating system. For this, the company is cooperating with the Open Source Automation Development Lab (OSADL), an international cooperative that promotes and coordinates the usage of open-source software for machine and plant control systems. Sercos (or the Serial Real-Time Communication System) is a digital interface for communication between controls, drives and decentralised peripherals.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
