Microbrewery illustrates PAC software uses, benefits

Opto22 whitepaper provides a quick tutorial.


Temecula, CA -- Programmable automation controllers (PACs) meet the complex demands of modern industrial automation applications because they combine features of more traditional automation technologies: programmable logic controllers (PLCs), distributed control systems (DCSs), remote terminal units (RTUs), and personal computers (PCs). If you’re considering a PAC for monitoring, automation, and data acquisition applications, you may be wondering how PACs are programmed. A whitepaper from Opto22 explores some of the most important features of software for PACs, using a microbrewery example.

According to the ARC Advisory Group, among a PAC’s defining characteristics are three elements directly related to software:

Because a key defining characteristic of PACs is that the same hardware can be used in multiple domains, including logic, motion, drives, and process control, it follows that the software must be capable of programming all control and monitoring tasks necessary in those domains. And the software must let the developer mix and incorporate these as needed into control programs, so these programs can “flow” as the requirements of the application dictate. The microbrewery example shows how this can be accomplished. Registration is free to the Control Engineering Resource Center, where the entire whitepaper resides.

You can also watch a six-minute OptoScreencast that introduces the programming environment for PAC Control Basic. Through it you’ll learn the basic building blocks of a PAC Control program and see how easy it is to build a tagname database and a control strategy using simple dialog boxes and plain English commands with Opto22 tools.
