With a high speed image bus, quad-core processing, high performance inspection algorithms and EtherCAT communications, the new FH compact vision system from Omron sets a new standard for speed, performance and versatility
T
ests carried out by Omron have confirmed that the FH vision system is the fastest of its type currently available, which means that users can achieve shorter machine cycle times combined with precise and dependable operation, even in difficult operating condi- tions. The resulting increase in machine efficiency translates directly into lower costs and enhanced competitive advantage. A further benefit is that FH vision systems are fully compatible with Omron Sysmac Studio Automation software. This means that only one software package is needed to set-up all of the major components used in an automation system, which greatly reduces the amount of work involved in machine design. Sysmac Studio can be used to set-up, debug and simulate all slave devices con- nected via EtherCAT, including not only vision and other sensing ele- ments, but also motion controllers, logic devices and drives.
A perfect fit
The FH offers the ideal solution for time critical positioning applications
machine and that is why Omron pro- vides control methods that eliminate work piece dwell time. The Sysmac automation platform achieves high speed, high precision control that continuously detects piece positions and compensates in real time, vastly reducing machine cycle time and improving machine performance - see image below. To ensure straightforward and dependable integration with all types of automation and control systems, Omron FH compact vision controllers incorporate support for the EtherCAT machine control network. This allows communication cycle times as short as 500µS to be achieved as well as allow- ing the implementation of motion con- trol that is synchronised with the communication cycle.

that involve the integration of machine vision with a motion control solution, and especially for machines that require micron precision where one alignment move is generally not sufficient to obtain the desired preci- sion. When multiple alignment movements are required, the process often extends the cycle time of the
At the heart of the new FH vision controllers is Omron’s innovative Shape Search III vision algorithm. Up to nine times faster when carrying out searches than conventional algo- rithms, Shape Search III allows fast, precise measurements to be made even if images are out of focus, or if the tar- gets are randomly positioned, ran- domly rotated or overlapping. This exceptional performance is achieved without the need for user dependent calibration, which means that FH vision systems are particularly easy to set-up and operate.
The FH controllers also support custom .NET controls, which means that images and measurement results can be easily integrated into machine user interfaces, providing a seamless view for operators.
Summary
Because of their exceptionally effi- cient image handling characteristics, the new vision systems can support eight high resolution cameras with no degradation of performance or image capture speed. The FH’s quad- core processor architecture also pro- vides the ability to have up to four completely independent trigger instances, which is unique for com- pact vision systems. This allows them to handle even the most com- plex of inspection tasks and, in some applications, it also means that a single vision controller can be used where previously several would have been needed, which leads to substan- tial cost savings.
