Detail Modular PAC For Process Control Mitsubishi
A platform to build on
The strength of System Q’ s automation platform really comes into its own in traditional specialist industries. The unique flexibility of proven off-the-shelf control components such as I/ O and communication devices, teamed with dedicated special devices like process CPUs, assures high functionality, ease of use and targeted control – all within budget.
Two worlds meet
Our dedicated System Q process CPUs build on the already high functionality of Mitsubishi’ s advanced platform. This powerful combination of sequential control overlaid with dedicated process instructions gives users a hybrid control solution with the best of both worlds.
This is complemented in turn by a range of dedicated channel-isolated and highresolution analogue modules. Here, too, a combination of specialist and standard modules provides the basis for practical and flexible solutions.
High system availability can be maintained through various means, including redundant process CPUs, stand-by network masters, and redundant network configurations, as well as by wire-break detection and a “ hot-swap” capability that allows modules to be replaced during live operation.
Programming can be implemented using a wide range of tools such as IEC1131.3 compliant software and the process-dedicated PX Developer.
Process CPUs
System Q’ s Process CPUs bring the benefits of standard System Q technology into the process environment, reducing both implementation and long-term running costs. These powerful processors combine standard sequential control with 52 dedicated process control functions, including loop controls with two degrees of freedom ( DOF) and highspeed PID control.
Redundant CPUs
Mitsubishi Electric’ s dual-redundant CPUs bring an additional layer of fault tolerance to the control of a whole system. This results in high reliability: if the main CPU, power supply or base unit fails, a secondary system starts immediately ( within 21ms) from the same control point.
For users this has two major benefits: no operational damage due to a single system failure, and production that continues seamlessly.
High reliability systems
The System Q automation platform can also be applied to other areas requiring high reliability, e.g. standby network masters, redundant fieldbus ( CC-Link) and redundant power supplies for remote I/ O stations.
In addition, selected analogue and temperature control units have a wirebreak detection feature enabling them to determine the difference between an actual signal and one that has been lost due to external system damage
