PFEIFFER EVR116 supports the following two types of report printing functions: one is periodic report printing, and the other is triggered report printing, the user according to the needs and preferences to generate different forms of reports. In the actual process control system, based on PID control technology accounted for more than 80% of the system, PID loop using the advantages and disadvantages in the realization of the device to achieve smooth, efficient, high-quality operation plays a pivotal role in the DCS manufacturers are used as a powerful competitive advantage to capture the market, the development of their own PID self-tuning software.

DCS in the control of the most important feature is to rely on a variety of control, computing modules, flexible configuration, can achieve a variety of control strategies to meet the needs of different situations, so that in the unit combination of instrumentation to achieve a rather cumbersome and complex proposition has become simple. With the requirements of high flexibility and high efficiency put forward by enterprises, the control scheme based on classical control theory can no longer be adapted to the advanced control strategy represented by multivariate predictive control has been proposed and successfully applied after the advanced process control has received widespread attention from the process industry.

PFEIFFER EVR116 widely apply various advanced control and optimisation techniques is the most effective, direct and valuable development direction to explore and enhance the comprehensive performance of DCS. In addition, according to the control function of DCS, on the basis of the basic PID algorithm, a variety of improved algorithms can be developed to meet the needs of the actual industrial control site, such as PID control with a dead zone, integral separation of the PID control, differential first PID control, incomplete differential PID control, PID control with a logic selection function and so on.
