Integrating frequency inverters into PROFINET environments, the modular PROFINET Box, from NORD Drivesystems, for cabinet-installed SK 500E inverters will be available from the second quarter of 2011, followed by a version for distributed SK 200E-type inverters. It cost-efficiently connects a large number of inverters to a single bus line, since there is no need for repeaters or additional bus master interfaces. The 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. Optionally, for distributed installation, the bus can be connected via an M12 circular connector. In addition, the decentralized box features eight integrated 24V inputs 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 protection rating of IP55, and can be supplied for IP66 on request.
