Process Control of Mitsubishi Modular PAC





A platform to develop
The strong point platform of System Q’s automation truly comes into its own in conventional high-quality industries. The distinctive flexibility of established off-the-shelf control elements for example communication and I/O devices, teamed with keen special tools like process CPUs, guarantees high functionality, simplicity of use and targeted control and all within budget.

Meet two worlds
The devoted System Q process CPUs develops the already high functionality of advanced platform Mitsubishi. This great combination of sequential control placed on top with dedicated process instructions provides customers a solution of hybrid control with the greatest of both worlds.

This is harmonized in turn by a dedicated range of channel isolated and analogue of high resolution modules. There is a combination of standard and specialist modules give the basis for flexible and practical solutions.

High system accessibility can be sustained throughout a variety of means, including process redundant CPUs, stand by masters of network, and redundant configurations of network, as well as by detection of wire-break and a capability of hot-swap that permits modules to be substituted during live operation.

Programming can be executed by a wide range of tools for instance IEC1131.3 compliant software and the dedicated PX Developer process.

CPUs Process
Process CPUs of System Q’s take the advantages of technology standard System Q into the process environment, sinking mutually execution and long term operating charges. Those great processors join standard sequential control with dedicated process of 52 control functions, comprising controls loop with two DOF (degrees of freedom) and high speed PID control.

CPUs Redundancy
Dual-redundant CPUs of Mitsubishi Electric bring an extra fault tolerance layer to the control of an entire system. This outputs in high dependability: if the power supply, main CPU, or base unit fails, a secondary system runs immediately (within 21milliseconds) from the equal control point.
For users there are two main advantages: no operational break because of a single system breakdown, and production that continues faultlessly.

High systems reliability
The automation platform of System Q can also be affected to other fields requiring high reliability, for instance standby masters of network, fieldbus redundancy (CC-Link) and power supplies redundancy for remote stations of I/O.

Additionally, chosen temperature control and analogue units have a feature of wire break detection allowing them to establish the difference between a real signal and one that has been missing because of external system spoil.
