Matching Device Drivers with Embedded Hardware
and the hardware interface with each other through device drivers. The selection of any piece-operating system, hardware or device driver-impacts the other pieces. In embedded systems consisting of both hardware and software components, the division of time has shifted from years past. Much of the complexity

Simpler controls lead to lower-cost pneumatics
model of car. Converting to a valve manifold and modular I/O embedded with DeviceLogix, used in a stand-alone fashion, reduced system size and complexity and increased fixture capacity to eight vehicle models. Cost savings exceeded $10,000. DeviceNet is a workhorse communications network with many fine

Servos adapt to their loads
of the XtraDrive includes inputs for step, direction, an analog velocity reference, and an analog torque reference. The XtraDrive comes standard with an embedded 1.5-axis controller to facilitate stand-alone or distributed-control structures. Network connectivity supports Profibus, DeviceNet

Which bus, when?
, DeviceNet, Ethernet, Foundation Fieldbus, Modbus, and Profibus. Several networks have had varying degrees of success. SDS from Honeywell competed with DeviceNet, but never gained wide acceptance. Interbus from Phoenix Contact has done well in Europe. And ASInterface has found a limited niche of smaller

The Web PLC is here
PLCs connect PCs to the factory floor over the World Wide Web. By Richard A. Baker Jr. The Momentum M1E line of PLCs come with embedded Web pages. The line includes a full range of I/O bases that accept a snap-on communications adapter, making it usable with Profibus, Interbus-S, DeviceNet, Modbus

Industrial networking: Intelligence from the ground up
acting as barriers along the way. Fieldbus protocols such as ControlNet, Profibus-DP, DeviceNet, and A-B 1771 RIO bundle data for transmission over the network. These protocols are designed for either the control or device layers of individual industrial networks. While effective, they make

Pneumatics troubleshooting gets easier
Embedded diagnostics in pneumatic valves gives advanced warning of impending failures. The Drive Diagnostic Link system monitors valve performance and sends diagnostic information directly to a PLC. DDL is a daisychained-serial link that forms a single fieldbus node. A newly developed

Touchscreens widen the outlook for LabView
with the CVS-145x Compact vision systems. The 5.7-in. TPC-2006 industrial touch-panel computer is designed for embedded or machine-control applications. The LCD monitor with resistive touchscreen runs Windows CE and .NET and is programmed with the LabView PDA Module. The module automatically compiles
