I know the prices of DDC are mostly lower than PLC, but when installing a new HVAC systems, with 10, 20 or even 30 Air Handling Units (AHU), one PLC that controlls all AHUs would be cheeper, isn't it?
All AHUs are simillar.
Does PLCs now have ready control modules for processes like these? which Vendor?
I need your opinion(s) regarding this issue with aspects of robustness, programming, working life time, networking, PID setting and more.
Thanx
