Operand Data type Function Setting range Description
present error meets
the cross status
The error value (E)
is the difference
between the SV
and the PV. When
the ERR_DBW
setting value is 0,
the function is
disabled; otherwise
the CPU PLC
checks
whether the present
error is less than
the absolute value
of ERR_DBW, and
checks whether the
present error meets
the cross status
condition. If the
present error is less
than the absolute
value of
ERR_DBW,
and meets the
cross status
condition, the
present error is
counted as 0, and
the PLC applies the
PID algorithm ;
otherwise the
present error is
brought into the PID
algorithm.
