12.The explanation of 32-bit S3 and 16-bit S3 are almost the same. The difference is the capacity of S3+5 ~ S3+20.

PID Equations:

1.When control mode (S3+4) is selected as K0, K1, K2 and K5:

y In this control mode, PID operation can be selected as Automatic, Forward, Reverse and Automatic with MV upper/lower bound control modes. Forward / Reverse direction is designated in S3+4. Other relevant settings of PID operation are set by the registers designated in S3 ~ S3+5.
