The documentation talks about Gain, Integral and Derivative, but doesn't tell the units of these parameters. Is Gain actual gain or Proportional Band ? Is Integral term a reset (e.g. min-1) or a time (e.g sec, min) ? Is Derivative term in sec or min ? Thanks.

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
