Can a PLC monitor a website?
(OP)
It is desired that data from the National Weather Service be available on the PLC network....is this possible? Or can you get something that pulls it up on the HMI's that are only connected to the PLCs?

I'm reading one of the requests a person at the plant has and it is for what I describe. There will be a separate LCD screen for the SCADA monitored points, voltages, currents, etc.. And I'm supposing he would like to see live data on current weather conditions in our area. Also I can imagine, that the weather at the time be known should we get an alarm - to perhaps prove that some of the alarms are occuring during adverse weather conditions.
Then again, this might be one of the things we scrap and tell the guy to get a good weather radio! I just thought if we can accomodate for little expense...why not.

In this application an excel spreadsheet extracts the info from the internet, and Citect looks at the spreadsheet
I would not recommend using the PLC for this unless it's a soft PLC i.e. B&R or somethingsimilar
