jabc Automation Posts: 5 Rating: (1)	hi! I'm starting a project with S7-1500, before I was working with s7-300 and indeed for the process I've worked with has failed me the module PID as the process variable is fast (speed), specifically I want to know if the compact PID module for s7-1500 I can work to make efficient control. thanks

jabc Automation Posts: 5 Rating: (1)	OK, thanks the specific question is the PID compact 2.x (CPU 1516-3) can work for processes where the controlled variable undergoes rapid changes eg. Speed, not only slow variables as temperature, pressure and level. Best Regards

Best Regards Hello, It depends on the case.For a fast response, hardware solutions are recommended while software solutions are bounded with CPU's execution and interrupts strategies.It is not possible to suggest any solution without adequate amount of information ,and more importantly, for a fast response to a process you need fast actuators, fast responding sensors and fast algorithm processing that are all available in hardware solutions customized for each technical case.

jabc Automation Posts: 5 Rating: (1)	Thanks Hamid I will work on this project with Simulation Tools TIA Portal to adjust the PID and then I will be commenting on this post my results. Best Regards
