With DeltaV™ Virtual CHARM I/O Card simulation you can rigorously test your control strategies, operator graphics, and I/O assignments prior to implementing on-line. The simulation has the advantage of reduced hardware staging and it frees up the real CHARM I/O cards for installation and I/O checkout at the production site. DeltaV Virtual CHARM I/O Card simulation provides a cost effective and easy way to simulate process I/O during control system development and checkout.
