true, the MV will be
output according
to the MOUT, but it
will be still in the
range of the
MV_MIN to the
MV_MAX.

Range of
single-precision

It is used for the
PID feedforward.

Range of
single-precision
floating-point
values
An accumulated
integral value is
usually for
reference. Users
can still clear or
modify it according
to their needs.
When the MV is
greater than the
MV_MAX, or when
the MV is less than
MV_MIN, the
accumulated
integral value in
I_MV is
unchanged.

MV REAL MV The MV is in the range of the MV_MIN to the MV_MAX.
Example:
1. Before the instruction DPIDE is executed, the setting of the parameters should be complete.
2. When X0.0 is ON, the instruction is executed. When M1 is ON, the DPIDE algorithm is
implemented. When M1 is OFF, the MV is 0, and the MV is stored in D200. When X0.0 is
switched OFF, the instruction is not executed, and the previous data is unchanged.
