Multi-axis drive incorporates PC

Paul Boughton
New from B&R is the Acoposmulti APC820 that integrates the highest level of PC performance into Acoposmulti multi-axis drive. This enables users to save even more space in control cabinets by freeing up space intended for the PC.

In the APC820, high-performance Core2 Duo processors ensure that the most demanding automation and visualisation systems run optimally. With the Core2 Duo, high performance and a low level of power loss are achieved because Windows XP and the real-time operating system run parallel to each other on separate processor cores. It is up to the user to reserve a processor core exclusively for real-time or to release it for Windows. The available computing power from both cores is optimally used. The project is easily developed in B&R Automation Studio.

Completely new options and complex automation tasks that were previously distributed over a number of system platforms (eg controller, Windows computer, etc) are now brought together in a single device. With the integrated Smart Display Link in APC820, up to four automation panels can be connected over a distance of up to 160m. Complex processes on physically separated machines can easily be controlled on site - which is a distinct advantage for commissioning, operation and service.

A wide range of onboard interfaces enables the APC820 to be optimally integrated in an automation system. Real-time communication between APC820, I/Os and drives occurs on the Powerlink interface, which also comes as standard. This helps achieve cycle times down to 200us and ultra-precise timing of less than 1us. The two Gigabit Ethernet interfaces provide machine-level communication that is separated from the connection to the company network. There is an additional Can interface available for the connection of additional devices.

The APC820 was designed for harsh environments. Not a single internal cable connection was used during construction. This has made it possible to achieve maximum vibration resistance and operational safety. Compactflash cards are used as the storage medium, which are also optimal for use in Windows XP professional as well as Windows XP embedded.
