Dear member
For more information on classical 3-term PID controllers
refer to the following links:

PID control and associated controller types

1-The classical three-term PID controller
2-Optimal tuning of PID controllers
3-Advantages and disadvantages of the different types of controllers

Also check following thread for sample program for
FB41 and SFB41.I think the samples would be a good
starting point to get the basic information.Also you can
get the official description of the function, select the function in
SIMATIC Manager and press <F1>.

FB41 PID example
