The PID2 instruction does not seem to follow the Modicon Book definition of Direct Acting/Reverse Acting PID.Is the book definition of the PID2 instruction Reverse/Direct acting configuration wrong? Plus wrong in all other documentation that I can find?
Both the manual and the online software help show that you must short the third input on the PID2 block for Reverse acting and leave the third input open for Direct acting. However, observed results show the opposite is true. Could someone just clear this up for me? Is this just a known documentation error?
Thanks for the help.
