Hi,
I just want to give my 5 cents of suggestions to this thread as well:
If it is a Siemens PLC, you could use a module called PLCSQL Link. It is a set of Siemens STEP7 blocks that you parameterize to your needs and download to the PLC. It works with all Siemens S7 PLC's that has a network port. It doesn't require any pc with driver or OPC server in between.
See www.plcsql-link.com
Otherwise you could use VB in most SCADA systems (as suggested by others above as well) to do archieve the same as well. But the problem with VB is, that if you need to make any changes to the fields you want transferred, then you need to change your VB code. And the problem with the VB implementation in most SCADA systems (Including RSView and WinCC/Flexible) is, that it is singlethreaded, so if something happens, the whole program freezes. Error handling is not an easy task to implement in VB.
