The PowerDNA® (Distributed Networked Automation) Cube is a compact, rugged, Ethernet based DAQ interface. Its flexibility allows you to configure one or more Cubes to match the specific I/O requirements of your application. The PowerDNA Cube is ideally suited for a wide variety of industrial, aerospace and laboratory data acquisition and control applications. The heart of every PowerDNA system is the Cube. The PPC9 Cubes are 4” x 4” x 6.6” (7 I/O slots) and are packed with power and flexibility. Each I/O Cube consists of two primary subsections: a Core Module and I/O slots or layers.
The Core Module occupies the top portion of the Cube and provides the PowerPC CPU, Ethernet Net-work Interface Controller (NIC), 9-36V DC Input indicator lights, timing/trigger interface, configuration ports and internal power supply. It controls the unit’s operations including the interface with the host Controller (and other Cubes) and supervising the activity of the I/O Layers.
The remainder of the Cube is dedicated to I/O slots or layers. These slots are populated with the I/O modules that are selected to match your process or test application. With over 60 different I/O boards available we’re sure to have just what your application requires. We currently offer: Analog input boards to measure voltage, current, strain gages, thermocouples and more, Analog output boards with outputs to ±40V or ±50 mA, Digital I/O interfaces for logic and “real-world” signal levels, counters and timers, quadrature encoder inputs, and Communications interfaces for RS-232, RS-422/485 and the CAN bus.
The host communicates with the Cube in one of three ways. The first is simple, single point, programmed I/O. This mode is simple and is suitable for most systems where high speed or precise sample timing is not required. The second is the ACB (Advanced Circular Buffer). In ACB mode data is written to and from buffers on the I/O boards rather than directly to the Ethernet port. ACB mode is preferred for high speed acquisition/control or where precise timing is required as the buffers are large enough to assure data is not lost due to Ethernet timing latencies. The third mode is DMAP. In DMAP mode, Cubes use our patented DAQBIOS Ethernet protocol to assure deterministic real-time performance and achieve sub-millisecond response times across more than 1000 I/O (analog and/or digital) points.
