Description
MV_MAX
REAL
Maximum output value
Range of
single-
precision
floating-
point
numbers
Suppose
MV_MAX is set
to 1,000. When
the MV is
larger than
1,000, 1,000 is
output. The
value in
MV_MAX
should be
larger than that
in MV_MIN.
Otherwise, the
maximum MV
and the
minimum MV
will be
reversed.
MV_MIN
REAL
Minimum output value
Range of
single-
precision
floating-
point
numbers
Suppose
MV_MIN is set
to -1,000.
When the MV
is less than
-1,000, -1,000
is output.
MOUT
REAL
Manual output value
It is used with the PID_MAN
mode. Users set the MV
directly.
I_MV (It
occupies six
consecutive
32-Bit
devices.)
REAL
I_MV
The
accumulated
integral value
is temporarily
stored in it.
Range of
single-
precision
floating-
point
numbers
The
accumulated
integral value
is only for
reference. It
still can be
cleared or
modified
according to
users’ need.
When the MV
is larger than
the MV_MAX,
or when the
MV is less than
MV_MIN, the
accumulated
integral value
in I_MV is
unchanged.
I_MV+1
The previous
PV is
temporarily
stored in it.
The previous PV is only for
reference. It still can be
modified according to users’
need.
I_MV+2

I_MV+5
For system use only
