Recipe based control/batch system that runs directly on Mitsubishi Electric's modular PACs

Batch process control

INEA is the leading Slovenian company in the field of automation, process and manufacturing informatics. With INEA’s C Batch tools running on Mitsubishi Programmable Automation Controller (PAC) hardware, the execution of recipes is relocated from the PC platform to a PAC platform. Recipe based batch process control systems are simplified for easier handling, without essentially reducing the expressive power and the abstraction level.

S88.01 style recipe running without the need for PCs in runtime operation, means increased security.

System benefits

C Batch provides all features you would expect from traditional PC-based batch control software, but with the reliability for which PACs are renowned, including:

* Simultaneous execution of several recipes with automatic allocation of units for increased productivity.
* Support for parallel (AND) as well as selective (OR) branches for improved flexibility.
* Execution of the state-transition algorithm of individual phases, extended by the notion of superstates to improve the abstraction level and simpler programming.
* High security of control system with isolation from computer viruses and windows OS problems reduces down time.
* Configurable behaviour related to propagation of holding transition from phases to recipe and vice versa provides flexible manipulation.
* Recipe versus physical model consistency check increases safety.
* High availability embedded database technology on PAC platform improves speed and safety.
* Scaling of recipe parameters and consequently scaling of production batches improves flexibility.
* Controller based architecture with extremely high reliability of standard industrial PAC environment improves safety.

The C Batch solution provided by INEA and Mitsubishi Electric meets the challenges of modern process control where it is essential to be able to develop and implement new recipes easily, and to make changes to existing recipes quickly, without creating the demand for complex and time-consuming programming – the goal of agile process control.
