This document shows examples of system architecture for PC-based I/O control systems and lists Opto 22 products that work together for PC-based control. System examples include:
- Ethernet systems using SoftPAC, a software-based programmable automation controller programmed with PAC Control
- Ethernet systems using the OptoMMP protocol
- Direct control of I/O using no I/O processor (no brain)
- High-speed control using the Pamux protocol
NOTE: Before choosing to use a PC for control, consider
groov EPIC. A
groov EPIC processor offers many features similar to a PC, such as a Linux OS with optional secure shell access; cybersecurity features; Ethernet, USB, and HDMI ports; and the ability to run the control program and HMI on the same hardware. In addition, a
groov EPIC system offers real-time control using traditional programming languages; guaranteed-for-life I/O on the same chassis; industrial toughness for hazardous locations; and easier integration with company computer networks, manufacturing, business, and facility systems, and cloud-based services & software.
