The Best Control Solution for Motion-Centric Applications

The SPiiPlusSC PC-based machine and motion control software provides demanding machinery with the highest performance possible at the most affordable price, leveraging on the processing power of modern PC technology and on the connectivity of a real-time open industrial Ethernet network. Now, a standard PC with Windows can run your machine application, the Graphical User Interface (GUI) and the SPiiPlusSC real-time motion controller and PLC without adding any hardware. Previously, the control solution to demanding applications, such as SMT assembly systems with high volume data transfer needs, was based on a dedicated motion controller card that plugged into the PC and a dedicated PLC . Not anymore!

The SPiiPlusSC control software, which includes its own real-time operating system, runs on one of the processors of a multi-core PC, and communicates with the host applications over shared RAM and virtual TCP/IP. The SPiiPlusSC manages all motor drives and I/O processes using one of the standard Ethernet ports of the PC as the EtherCAT master communication channel. The result - the highest performance and most flexible controller at the best price. The SPiiPlusSC is also a more cost effective, state of the art replacement for standalone motion controllers and PLCs. It is more powerful and it simplifies the connectivity of the entire system by eliminating the dedicated controller hardware.

A Natural Evolution of ACS’ Technology revolutionizes the Motion Control Industry

Since 1990, ACS’ motion controllers have utilized a distributed computer platform to answer the needs of demanding machinery. This platform consisted of a dedicated small form factor PC (MPU) and a few Servo Processors on one card. The MPU executed the high level tasks, including communication with the host application, program execution, I/O processing, diagnostics and profile generation. The Servo Processors received the profile information and executed the real-time control algorithms. The MPU communicated with the Servo Processors over a PCI bus.

In ACS’ new line of distributed controllers, the PCI communication channel between the MPU and the Servo Processors is replaced by EtherCAT. It provides significant benefits in addition to cost savings: physical distribution and scalability. Now the Servo Processor resides within the drive. All issues related to the integrity and safety of a fully distributed control system – how to respond to a servo processor failure, a MPU failure, or a communication channel failure - have long ago been resolved in the SPiiPlus architecture. In a SPiiPlusSC based system, the dedicated MPU is eliminated and, instead, the software runs on one core of a multi-core host PC.

As a member of the SPiiPlus family of controllers, it shares all the powerful features of these controllers regarding programming, motion modes, special I/Os, data recording and support tools. Previous applications that have been developed for a SPiiPlus controller will run on the SPiiPlusSC as is or with minor modifications.
