PAC Based Batch Control
Solution Eliminates the need for PC’s on the Plant Floor
Traditionally implementing effective batch control
systems has meant a PC-based installation coupled within
the real-time control loop often communicating to the
shop floor controller via OPC, but there are inherent
programming, integration and security issues around such
an installation, as well as the lack of robustness of
PCs on the plant floor. Now Mitsubishi Electric has
addressed these problems with C Batch, a PAC-based batch
control solution developed with process control
specialist INEA.

Compliant with ISA
S88.01, the software delivers the essential features
of recipe creation and management, creation of
batches and control of their execution, automatic
execution of recipes, and simultaneous execution of
several recipes – all without leaving the familiar
and secure PAC environment. The operator interface
is provided by the Batch View software running on
Mitsubishi Electric’s GOT series HMIs.
The C Batch system runs the complete Batch engine,
with recipe management, within the PAC. This removes
the need for a PC based batch server, simplifying
the overall system architecture, reducing
implementation speed and costs without sacrificing
performance. Furthermore, by operating within a PAC
environment there is a reduced exposure to some of
the traditional software and hardware based IT
security issues. One example, which is often
overlooked, is that the PAC hardware is locked away
in an enclosure with limited direct personnel access
unlike the PC which sits temptingly on a desk. In
addition, by using a non-PC based system there is a
greater resistance to malware infection.
Naturally the C Batch
solution provides all the features you would expect from
traditional PC-based batch control software yet expands
on this by enabling the execution of state-transition
algorithms for individual phases. This extends the
notion of super states to improve the abstraction level
and simplify programming, in short it makes it easier to
implement and react to changes within the process.
Further, the configurable behavior related to
propagation of holding transition from phases to recipe
and vice versa provides flexible manipulation, while the
recipe versus physical model consistency check increases
safety.

In addition the scaling
of recipe parameters and consequently scaling of
production batches is key to improving flexibility. And
because C Batch is PAC-based, batch cycle times are
minimized and deterministic speed of execution
optimized, helping to improve productivity.
AMD Development Manager, Thomas Lantermann, comments:
“To meet the challenges of modern process control, it is
essential to be able to develop and implement new
recipes easily without creating the demand for complex
and time-consuming programming. Of course there are
PC-based solutions to do this, but many manufacturers
prefer the greater simplicity and reliability of
PAC-based systems. The use of PACs is increasing as many
believe it brings a greater degree of application
robustness to process control tasks by making use of
industrially proven hardware, often reducing the risks
of malware infection.”
