It offers an architecture where control function like analog scaling, digital counting, and PID loop control are distributed to I/O processors. New functions include frequency measurement for determining the frequency of digital states and used to read the speed of rotating machinery, velocity encoders, etc.; period measurement for determining how long a digital point remains on or off; analog totalization for sampling and totaling analog input readings at predetermined intervals; and digital totalization for determining on-or-off time of a digital input.
Upgrades to the HMI development and runtime portion include a security feature for user login and logout that captures operator actions during runtime, new runtime features show the origins of controller and I/O data, new multimedia alarming capabilities associate and play unique sound files with individual alarm notifications, and support for 64-bit integer tables exchanges large data arrays with the PAC controller.
