Real-time I/O Control Suitable for Multiple Domain Applications

Currently most PC-based controllers face one major challenge, especially DIN-rail PAC

systems, which is real-time I/O control. Performance is severely hampered when I/O points

increase because the access time also increases, which impacts control precision as well.

Food and beverage companies face shorter production runs on a wide range of products

for different vendors, while automotive companies are dealing with changes in customer

preference, aggressive competition and rising fuel costs. These industries require a mix

of discrete, batch, process and motion control solution. In the past, these applications

forced engineers to use multiple controllers: a PLC for discrete control, a motion controller

for multi-axis control, and a distributed control system or loop controller for process

applications, which has proven time consuming and costly. Advantech PACs feature the

ability to handle all these tasks with a single control system.

The result is shortened development time through reusable programming tools, lower

maintenance costs through reduced parts, better information sharing among applications,

and fewer personnel support throughout the plant.

Information Processing and Networking Capabilities

Advantech PACs not only provide excellent real-time I/O control, but also another key

beneﬁt for automation applications, information processing. With the ability to perform

ﬁeld operations, data exchanges and valuable information collection, this series is able

to execute efﬁcient decision-making. Information processing includes data logging and

analysis with storage devices like SD or CF cards, recipe management for batch control,

and database exchanges through SQL and OPC. Furthermore, implementing HMI software

enables local operation.

This improves control system networking tremendously, allowing the network to share a

common protocol at the device level, control level, and information level. It provides the

ability to move information from the device level to executives at the enterprise resource

planning (ERP) level without new protocols or drivers.

Advantech PACs feature a PC-based architecture, delivering signiﬁcant networking beneﬁts

for manufacturers by USB, RS-232, RS-422/485 and Ethernet interfaces. Users can connect

to ﬁeld devices through serial or USB interface to satisfy any kind of application. The

Ethernet interface allows users to effectively manage I/O control and information ﬂow

throughout the manufacturing and IT enterprise. Leveraging the high computing power

of Advantech PACs also allows networks to communicate seamlessly on the factory ﬂoor

with other common sets of IT capabilities like video, data and telephones. Easy access

to such information is critical to making decisions about the capacity of an enterprise.

Scalability

In the past, many PLCs required users to learn different programming software and specify

networks depending on the size and complexity of the application. Advantech PACs allow

users to more closely match the controller to application needs without compromising

functionality or learning a new control system. Such scalability reduces the headaches

and high costs associated with system redesign, lack of program re-use, and re-training.

Software

Advantech PACs support software to satisfy both PC-based and PLC-based programmers.

Leveraging IEC 61131-3 SoftLogic programming environment, PLC programmers can

take PLC operations to the next level in many areas, such as communication, information

processing, enterprise level database integration, and user interface development.

For PC-based programmers, Advantech offers an open platform solution, with C/C++

and .NET libraries for I/O control and communication functionality. They can satisfy

programmers familiar with high level programming languages like Microsoft Visual

Studio .NET. In addition, several convenient utilities are offered to save development time.
