monitoring and change PLC parameters through Internet


Thread Starter


hi list ....
I am looking for a system that allows to visualize variables and to change parameters of any type of PLC through Internet.
The system would have to adapt to the existing equipment without changing the communication protocols.
If possible the remote control would have to be made through an Internet navigator.

Emation has a product named "WebOPC" that reads/writes from and to OPC Servers (= multiple PLC vendors) and uses the real-time data to animate Java Based Graphics which run over Internet

Alternative, buy an HMI from vendors whose HMI supports some sort of Web navigation (or scout) or what-ever they call it. If the vendors HMI provides enough channels to the PLC's you are done
