[g7171 0]

Hi all, I need improve a system. We have 3 machines (3 PLC and 3 HMI); a machine (pair of PLC & HMI with ethernet) controlling movement of motors of others ones and others two machines with themselves process. Now, we want send information, from a database in PC (as server), to the PanelView when we call information from these and write it in PLC address, somebody has experience or example about it? Any help would be appreciated.

Look at our http://pvbrowser.org It is a framework for HMI SCADA which is client/server. You can surf a whole plant from 1 client. This is almost like browing the web but pvbrowser is especially designed for process visualization. You can communicate to any number of PLCs. It supports almost any database system (any database system that is supported by Qt).
