May 18, 2011 - NORD Announces PROFINET Technology Unit. With no need for repeaters or additional master interfaces, the PROFINET module connects a large number of inverters to a single bus line. The technology box supports real-time data transfer and features an integrated Industrial Ethernet switch, an integrated web server, and a PROFINET status display. Optionally, fiber optic lines are also supported.
The bus module for distributed control 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 module via an RJ45 plug connector.
Optionally, for distributed control, the bus can be connected via an M12 circular connector. In addition, the module features eight integrated 24V inputs and two 24V outputs. Thanks to gateway functionality, a single PROFINET technology unit 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 distributed modules have a standard protection rating of IP55, and can be supplied for IP66 upon request.
