Purchase and OPC Server that will allow you to communicate with the device and then wite your own OPC code in VB. The cost of this depends upon what version of OPC you are using.

If you're using a Q-series PLC then there are a few options. There is the MES module (both the MES interface IT and the regular MES module) and also there is a datalogging module that you can get that will send information to a PC. The MES modules transfer information to a database and once that information is in the database you can do whatever you want to it (it's just a SQL database). The datalogging module has software that comes with it but I have yet to play with it so I can't tell you a lot about that one.
