InTouch (Wonderware) is a visualisation tool from the enterprise-level system "FactorySuite".
So you can not directly compare it with LabVIEW. It depends on what are you developing.
I used InTouch 8.0 about 3 years ago for one project (about a year) and don't pretend to be a judge. I don't know its current state (it seems to be IT 9.5).
IMHO
Some of InTouch advantages:
- Very easy way to communicate with PLC's. Dozens of IOServers for different PLC's brands and communications channels (serial, TCPIP, etc.).
- Very easy way to use touch-screens.
- Reliability.
- As a part of the FactorySuite, it can be easily connected with the factory-level information system (Industrial Application Server, InSQL, etc.)..
Some InTouch disadvantages (IT 8):
- Very poor programming language (QuickScript). It did not even have arrays! (To manage array of strings, I used invisible ListBox
🙂 )
- The license price depends on the number of supported tags. As the language does not have global variables, one has to use "Memory Tags" instead.
- Developers have to renew the developer's license every year. You have to buy RT licenses for every targe computer.
