I have an application to control the an industrial process by time schedule 24/7/365. The PLC end is simple. I would like to use PC over Ethernet to update the PLC schedule from a nice GUI that is user friendly and available across the network or even on smartphones.
Do you have any experience with 3rd party or open source software to do this, seems like building automation folks must have this off the shelf. No point in reinventing the wheel.
Thanks
