Problem

Customer is working with ISaGRAF 3.22.

When He tries to make his application he gets an error message stating: "Too Many IO Variables"

What does this error mean and how do I get it to go away?

Solution

The error message indicates that the number of I/O variables configured in ISaGRAF exceeds the number of allowed by the ISaGRAF License.

You can see how many IO variables you are licensed to use from the Project Management window by selecting Help > About.

To see how many IO variables you are using you will need to open up the dictionary and count the number points configre as either Input or Output.
