i am involve in project that needs to control temprature of process with PID func. FATEK FBs-PLC. is there any method to estimate the parameters of related function (func 86 in fatek instructions) such as Ki, Td, ....? there is not transfer function of the system.
 
It is a very useful instruction where instead of p, ti d you can use R registers and values can be moved to these registers.
It works superbly.

Thanks.

Hi,

There is the default values for these parameters:
Kc=110, Ki=17, Td=50. Almost it's good. If you need to change please see the function 86 TPCTL description.
