I did a project last year that involved using the ISA Algorithm in a PID. That project was written in PAC Control 9.3. I am using PAC Control 9.6c. When I try to use the PID Loop, it says ISA Obsolete and I can still chose it from the list, but for some reason it sets my Lower Clamp to -0 and my Positive Clamp to 0 (in Debug Mode). Which makes the Loop useless. Any thoughts of what I can do?
