Project execution with a new generation control system: Honeywell Experion PKS Honeywell Integrated Virtual Environment (HIVE) uses Lean project execution principles (the Honeywell LEAP process introduced in 2014), software and networking to decouple control applications from physical equipment, and controllers from physical input/output (I/O) devices. Modular designs allow multiple controllers to form one virtual controller. PKS stands for process knowledge system. Courtesy: Honeywell Process Solutions
