Today we are far removed from this, PLC’s are the main part of control systems worldwide. They integrate with field devices, perform motion control functions and can either be used for stand-alone single machine functions or part of a larger distributed control system within a facility. Modern PLC’s are extremely robust and versatile, all the major brands invest heavily in continued development of their range’s, adding more functionality, speed and processing power, together with add-ons such as expanded I/O and control module options.
HMI's present system data to the operator, give visuals of the industrial operation and link to SCADA systems and databases to provide key diagnostic data such as, trending, scheduled maintenance and real time visibility of the system. Within in this hub you can view and post all things PLC and HMI.
