Just as a matter of interest I have just quoted a project with Adroit. It only had a serial driver for Omron PLCs but now has an Ethernet driver. I do not like OPC - have had too many bad experiences.
The second licence for a second computer is quite cheap although the initial licence compares with Citect. The good thing about it is it uses very few resources - runs on the smell of an oily rag so to speak.
If we win the job I will do a comparison between Citect and Adroit - if not, no comparison.
One of my customers has an extensive network of Siemens PLCs hooked up to Citect. He has converted to the PSDirect driver and highly recommends it - his tag count is now over 110,000 tags.
