Baldor Electric Company's KPD202-501 is a compact
IP65-rated operator panel with a CANopen interface. The operator panel features
a backlit 4-line x 20-character LCD surrounded by six programmable function
keys. A further 15 keys are provided for the input of numeric values, together
with four pairs of keys which can be used for functions such as jogging
individual machine axes.
The panel can be
accommodated with minimal impact on layout and requires a rectangular cutout in
the fascia; built-in mounting clamps secure the unit by compressing its bezel
gasket against the surrounding fascia. Once mounted, the panel has an IP65
protection rating. The connections that are needed are a 24V dc power feed and
the desired communications link. The panel is equipped with a CANopen port,
which offers a choice of D-type and RJ45 plug-in connectors and a user-selectable
RS232/485 serial port.
programming software or tools are required and the KPD202-501 can be programmed
direct from the motion controller to which it is connected, using Baldor's
versatile Mint programming language. The operator panel is compatible with
Baldor's NextMove multi-axis controllers and Mint programmable drives,
including the new Mint Lite versions of the MotiFlex e100 and MicroFlex e100.
Where CANopen is not available, the panel can be operated as a standard VT100
terminal over its RS232/485 serial port.
plug-in I/O expansion module is available. The module provides four
optically-isolated digital inputs and four optically-isolated digital outputs,
each of which can be operated over the CANopen bus as standard DS401 remote
I/O, for use with ancillary devices such as push button interfaces and
indicator lamps. The inputs can be configured as PNP or NPN, whilst the outputs
are PNP only. The I/O can be directly controlled from within the Mint language.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
