Ruggedized I/O Controls

cpaDuring the past few months Autonetics received several inquiries regarding our control infrastructure and what types of hardware are best suited for certain applications. Currently there are three main control hardware platforms in use; Programmable Logic Controller (PLC), Hybrid PLC and Industrial PC.

Historically, the PC has endured the perception of three short-comings: stability, reliability, and unfamiliar programming environment. The PC’s general-purpose operating system was not stable enough for control. PC-controlled installations were forced to handle system crashes and unplanned rebooting. With rotating magnetic hard drives and non-industrially hardened components, such as power supplies, PCs were more prone to failure. Plant operators needed the capability to override a system for maintenance or troubleshooting. Using ladder logic, they knew how to manually force a coil and patch code to quickly override a system. But with PC systems, machine operators needed to learn new tools. 

One approach for automation control is been based on the installation of a programmable logic controller (PLC) from a leading vendor. Such PLCs have typically been expensive, proprietary systems, when you select a particular vendor and PLC family you are locked into the corresponding boards and functions that are available to that particular line. While this approach offers easy-to-integrate hardware, high quality components and knowledgeable support, it also is closed to unusual implementations or deviations from standard configurations. The options for programming the PLC have been limited to ladder logic traditionally and more recently cross PC /PLC programming. 

Using a PLC to meet modern application requirements for network connectivity, device interoperability, and enterprise data integration present other challenges. These types of tasks are usually more suited to the capabilities of a computer (PC). To provide these capabilities in a PLC-based application, additional processors, network gateways or converters, “middleware” software running on a separate PC, and special software for enterprise systems must often be integrated into the system. 

Many businesses want advanced, high performance industrial controls that also provide versatility and require limited capital investment. Autonetics value added line of hardened industrial digital I/O platforms offers a full range of features for complex application monitoring and control. With a broad range of uses, it can function as an operator panel, a machine control platform or inspection data collector. Available with a wide variety of expansion and peripheral choices along with the option to bundle our proven software, Autonetics embedded PCs equal the quality of PLC hardware. 

LP3A1456

Incorporated in our controls is a selection of resilient and fanless industrial computers based on the Intel Atom N270 processor. The PC provides embedded I/O functions and offers configurable PCI and/or PCI Express slots providing a rugged industrial platform for the client. These platforms combine the x86 platform design, versatile I/O function development, and thermal design to push fanless systems to a higher standard. With express data acquisition, expanded digital I/O, motion control, and image capture cards it is perfectly suited for industrial automation, factory control, and test instrumentation applications. Internal fixtures include a purpose designed single board computer to fit the respective fanless chassis where all heat-producing components come in direct contact with the aluminum shell. This allows for one of the widest operating temperature ranges among industrial computers. All connectors and components are mounted directly onto the PCB so there is no internal wiring. Such cable-free design significantly increases reliability and durability
