PROFINET interface for distributed and control cabinet inverters
20/04/2011 NORD Gear (UK) Ltd
Abingdon, UK - NORD Drivesystems supplies technology boxes for the integra-tion of frequency inverters into PROFINET environments. Modular units for cabinet-installed SK 500E inverters are available from the second quarter of 2011. In the fourth quarter of this year, a version for distributed SK 200E-type inverters will follow. The new PROFINET box from NORD cost-efficiently con-nects a large number of inverters to a single bus line, since there is no need for repeaters or additional bus master interfaces. The technology box supports real-time data transfer and features an integrated Ethernet switch, an integrated web server, and a PROFINET status display. Optionally, fiber optic lines are also supported.The bus module can be mounted either directly on the inverter's interface unit or separately from the inverter by means of an optional wall mounting kit. The PROFINET bus line is connected to the box via an RJ45 plug connector. Op-tionally, for distributed installation, the bus can be connected via an M12 circular connector. In addition, the decentralized box features eight integrated 24V in-puts and two 24V outputs. Thanks to gateway functionality, a single PROFINET technology box can address up to four inverters. An integrated RS232/RS485 interface allows for on-the-spot access to the parameters of the connected bus module and inverters by means of the SK PAR manual control unit or via NORDCON PC software. The decentralized modules have a standard protec-tion rating of IP55, and can be supplied for IP66 on request.
