var fDesc=new Array(); fDesc[0] = "OptiControls Loop Simulator software allows you to interact with and tune simulated process control loops. The simulator mimics various processes, controller options, disturbances, and control valve issues. This real-time simulator clearly and effectively demonstrates the essentials of process dynamics, PID controllers, control loop tuning, and more. It is supplemented with a comprehensive set of step-by-step practical exercises to guide you through many aspects of controller tuning and loop performance, while you gain first-hand experience on life-like control loop simulations."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
