(Click here for a larger view of the B&R APC620 Embedded)The APC620 Embedded (above, and below right) is bundled with B&R's Automation Runtime AR106 or AR010 software. This kernel lets Windows XP applications operate concurrently with a true real-time operating system, such as Wind River's
VXWorks. The two OSes communicate via TCP/IP, but the real-time OS always has the higher priority, ensuring deterministic control of PLCs, according to B&R.
The device is part of an overall APC620 product line that features four housing types, including variants with one, two, or five PCI slots. The devices run fanlessly, thanks to large exterior heat sinks and the use of Compact Flash storage instead of hard disk drives.
B&R's APC620 computers, with the APC620 Embedded at rightA key feature of the APC620s is their SDL (smart display link) feature, which allows eight touchscreen displays to be connected to each computer using a bus topology. The systems have dual SDL buses, each capable of cloning content to four displays on cable runs of up to 524 feet. The SDL cable runs also carry USB signals -- allowing USB drives and keyboard to be connected remotely -- plus touschscreen signals, key presses, and service data such as temperature and operating hours.
As the junior member of the family, the APC620 Embedded does not have a PCI slot. However, it has three fieldbus interfaces, which allow the system to be connected to dozens or hundreds of instruments and PLCs (programmable logic controllers) in a manufacturing plant. The fieldbus standards supported by the APC620 Embedded are Powerlink, CAN (controller area network), and X2X Link.
