SNAP PAC System

The PAC Project Software Suite from Opto 22 provides all the software you need for industrial automation, remote monitoring, and data acquisition applications in any field. One of four components of the SNAP PAC System, PAC Project software is fully integrated with SNAP PAC controllers, brains, and I/O, making it easy to understand, select, buy, and apply an automation system for your needs.

While the idea of combining PLC and PC-based technologies for industrial control has been attempted previously, it has usually only been done through the "add-on" type of approach described earlier, where additional middleware, processors, or both are used in conjunction with one or more PLCs. A PAC, however, has advanced capabilities needed built into its design. For example, to perform functions like counting, latching, PID loop control, and data acquisition and delivery, a typical PLC-based control system requires additional, and often expensive, processing hardware. A PAC has these capabilities built in.

Brains are I/O processors that provide distributed control. Brains perform basic control functions such as on/off control, counting, and latching, as well as complex tasks such as PID control and temperature conversion.

Brains communicate either over Ethernet or Serial (OptoMMP Protocol).
