What is the PID rate change?
If you have a database with many PIDs on Opto controllers, you might want to raise the evaluation rate of all PIDs. Because all processing of logic for Opto controllers is done on the DPU, many PIDs can cause a heavy processing burden on the computer. This is not a problem with BASNet controllers.
The default rate for PIDs is 5 seconds and the Rate can be changed on the PID Program Screen. However, you can change all PIDs together from the PID Rate Change button. See the figure below:
The PID Rate Change screen will tell you how many BASNet (CNET) PIDs and Non-BASNet PIDs are in the database. Input the Rate in seconds for both types of controllers separately then, click Change Rate for all PIDs NOW.
