I am sure that you are correct, yes the data input is a large part of the problem. The understanding of the person putting the data in must be good. And the design standards - the way you use InTools - are very important.
But did you really have No problems? Did you never have to fix the InTools output before you could use it? Or even find errors in the InTools database as you tried to configure the Control System?
In fact I would say that it (using InTools export data) is a very good thing to do, for all the problems, because it picks up errors before they get to site. But it is far from seamless.
Also, there is no way that InTools can store all, or even a significant proportion of the data that a DCS/PLC requires. It just does not have the structure to do so. Yes, hopefully scales, ranges, some descriptions, maybe even IO addresses. But not the logic, or loop configurations, the many parameters such as alarm settings, set points etc.
