Parker Hannifin's IQANdesign 3.0 software allows for the easy implementation of distributed machine control, diagnostics and user interfaces in a multiple master module environment. The software is easy to learn and use and requires no previous programming skills or knowledge. It supports an electronic approach for quickly, simply and cost-effectively controlling and monitoring hydraulic systems in mobile machines such as reach stackers, man lifts and other equipment used in sectors including forestry, materials handling and construction.
The integration of multiple master modules in a single system is made much easier by IQANdesign 3.0. This allows customers to enjoy the significant benefits and flexibility of a multi-master system without the need for the application engineer to define proprietary protocols for real-time data and diagnostics The major benefits of such a system include distributed functionality and diagnostics, a distributed human machine interface (HMI), extended memory capacity, faster cycle time and additional I/Os. Capabilities such as remote diagnostics, back-up, multi-master simulation in a PC environment and ‘limp home’ are other enabled features that can add to overall system convenience, safety, performance and robustness. The ability to run control loops remotely on separate masters can also give the speed of operation essential for functions such as active hydraulic damping.
The multi-master functionality also simplifies the integration of safety functions in the machine control system. The IQAN-MC3 is a safety controller designed and certified in accordance with IEC 61508, and can be used to implement safety functions of up to SIL2. When applying EN ISO 13849-1 for functional safety, it can be used as a PLd subsystem.
