Good afternoon!
We are running an application to control an oven with recipe, ramp and landing, using a V430-J-RA22.
The customer has a table where he puts the values of initial temperature, final temperature and time to leave the initial temperature and reach the final temperature.
To reach the value of how much the temperature setpoint should be increased, we use the following equation:
Final Temp - Start Temp / Time
Ex: 250-120/90 = 1.44 ° C per minute -> that is, the setpoint must be increased by this value every minute
In this way, we take this value and store it in a memory to insert in the PID control.
However, this only accepts whole numbers (MI), but for decimal places after the comma we would have to use one (MF).
Is there anything we can do or is this a limitation of the software?
