OK! Where to start. I have several sites online with a DSL or Dial up close by I need to send the data from the PLC to my server from several states. I would like real time data but 2-3 minute updates will be fine. I have read about some HMI software companies that allow you to publish HTML files and send them. (is this a data stream or snap shots?) I also feel that HTML's file has tons of graphs and the file is quite large I will also need a PC at every site. I may be limited on the amount of data I can view at one time from some of the other sites.
Is it possible to send the data directly from the PLC across DSL or Dial up into the server, I will then put the HMI software on the server and write my graphic screens there to view several sites, data trend, alarm notification.
Will this work or do I have my head somewhere it doesn't belong!
