The last few days ive been searching the web, for ways to get started on getting a plc to work with a database. I keep running my head into high prices, from various companies with a complete solution.
I dont have a specifig task or anything like that. First of all. I just want to find out if its possible to make a some entry to a sql db, when i set a bit in the plc or something simple like that. Without costing alot of money.
Once i made an experiment with exporting winCC recipe to a csv. file, then parsing it with a simple php script. And then showing it in html. This worked fine, but seemend a little amateur.
I want to take this a step further with for instance sql and opc.
Any ideas where to start will be much appreciated.
Im running step7 prof. v5.5 and winCC flex 2008
