Real-time Data Acquisition, Control, and Hardware-in-the-Loop Validation

VisSim/Real-TimePRO interfaces VisSim to popular analog and digital I/O boards and devices from National Instruments, Measurement Computing, and Quanser. VisSim/Real-TimePRO provides the capability to couple a VisSim system model directly with a real PLC or DCS system for off-line tuning, or to prototype a VisSim control with a real plant. With VisSim/Real-TimePRO, hardware-in-the-loop (HIL) systems can be configured and executed by interfacing VisSim plant or controller models with real-world hardware, such as manufacturing plants, chemical processes, motors, pumps, and electric drives. The interface to the real-world hardware is through computer I/O cards; high-speed motion control interface cards; or serial port connections to Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCSs). There is no code generation or programming involved to configure an HIL system with VisSim/Real-TimePRO.
