The Snap PAC system integrates hardware and software for IIoT, industrial control, remote monitoring and data acquisition applications. It consists of five components: analog, digital and serial I/O modules for wiring directly to field devices, machines and sensors; PAC brains—intelligent I/O processors for distributed control on Ethernet and serial networks; standalone or rack-mounted industrial controllers with networking options and a RESTful API or a software-based controller; PAC Project software—flowchart-based control programming, HMI development and runtime, plus options; and groov—a tool for building and using custom mobile operator interfaces and system dashboards to monitor and control systems and equipment from any web-enabled device.
