The PAC Project Software Suite R10 supports the groov EPIC system, adds eight control commands and provides the ability to designate individual I/O and variable tags as Public Access for read-only or read-write use in IIoT data communications via MQTT/Sparkplug. As in previous versions, HMI programming is included, and it uses the same tag name database as the real-time control engine, creating automatic integration between the two functions. The suite’s control programming software, PAC Control, is full-featured, with more than 450 commands in plain English, as well as graphical PID tuning and debugging.
