That being said, I/Gear would be the perfect solution to your problem. Derek McFarland () mentioned I/Gear in a post up above. Price is 800 USD.Ī bit of disclosure first. As I have my WinCC Flexible HMI, I could simply setup tags from one OPC server to be transferred to the other OPC server in my HMI. On the OPC side it is a server, so I have to do something extra to transfer the data from one server to the other. I would like to experiment with its many features. I dont like that, despite the supplier has promised to provide help. In order to transfer data from the ODBC database to the PLC I have to write some scripts. For a 150 tags license I have to pay 3000+ USD.

Could be interesting to try the software out anyway. Price of 2000 USD is sligthly ofputting for transferring 5 (which it turns out to be now) values. This sort of tells me that they are not up to the task.įactorySql is a favorite, this only because of praise from users on this forum, and because the setup is done without scripts or strange coding. The customer prefers to do everything by himself, but on the other hand I get questions back such as "What is OPC ? Can you provide some information about it ?". It is going slowly with getting the information from the customer, and getting an agreement on who does what.

If I have to do it cyclically or triggered, I do not know at the moment.

I probably have to fetch 10 values from the same records in database.

It sounds interesting, but 2000 USD is a little steep for my modest requirements. I should have remembered Inductive Automation myself. So far I am only assuming it is an ODBC database. If your crafty enough and can not forsee spending the money on an already programmed suite such as Inductive Automation, Citect, etc. There was a topic on it not long ago and there was also a link to a video about it on you tube.

And of course the big if is if you can program in VB, then you might want to search this forum for Free Scada. However if your reuqirements are very modest and you dont see a lot of big time growth which would warrent that kind of cost. I normally agree with Nathan, especially when it come to this type of application.
