Name R/W Description
Reg. Range Res.
C044 PID deviation level
setting
R/W Sets the allowable PID loop error
magnitude (absolute value), SP-PV,
range is 0.0 to 100%, resolution is
0.1%
1129h 0 to 1000 0.1 %
C052 PID FBV function high
limit
R/W When the PV exceeds this value,
the PID loop turns OFF the PID
second stage output, range is 0.0 to
100%
112Eh 0 to 1000 0.1 %
C053 PID FBV function
variable low limit
R/W When the PV goes below this value,
the PID loop turns ON the PID
second stage output, range is 0.0 to
100%
112Fh 0 to 1000 0.1 %
