In this case, the input data word, IR 010, contains #0014, and f(0014) = #0726 is
output to R, IR 011.

Limitations
C and C+32 must be within the same data area.
Note
Do not program PID(––) in the following situations. Doing so may produce unex-
pected behavior: In interrupt programs, in subroutines, between IL(02) and
ILC(03), between JMP(04) and JME(05), and in step programming (when using
STEP(08) and SNXT(09)).
Description
PID(––) carries out PID control according to the designated parameters. It takes
the specified input range of binary data from the contents of input word S and
carries out the PID operation according to the parameters that are set. The re-
sults are then stored as the operation output amount in output word D.
PID parameter words range from C through C+32. The PID parameters are con-
figured as shown below.
