Continuous Control Functions
PID CONTROL BLOCK
2-26
63 Preact Time Base Value (BPREACT) ............................................................................... CWR
The preact time base value can be any floating-point value in the range of 0.07 to 32.0
minutes. This derivative time filter is typically used on temperature inputs that have smooth
changes and lags and not on flow signals that are typically noisy and have no lags.
OFF Preact Time Base Value is 0.0. Preact response is off.
value Any floating-point value in the range of 0.07 to 32.0 minutes.
64 Manual Reset Initial Value (MR) ....................................................................................... CWR
The manual reset value can be any floating-point value in the range of -10 to 100%. This
value is reverse calculated from the output whenever the PID calculation is reinitialized when
going to auto. Manual reset is used with proportional only controllers. It cannot be used with
automatic reset (control action type must have reset off).
65 Manual Reset Quality (MRQ)............................................................................................– WR
Manual reset quality is determined by the quality of the output value, output mode and manual
reset calculation.
GOOD 0 Quality when the block is RUN or HOLD or no calculation error
occurs.
BAD 1 Quality when the block is off or when either the output value or output
mode quality is bad during the manual reset calculation or the manual
reset calculation is in error.
66 Control Modes Allowed (CMA).........................................................................................C – R
The control modes allowed are determined by this count value attribute.
M 1 Manual Control Modes Allowed.
A 2 Auto Control Modes Allowed.
A.M 3 Also M.A. Auto/Manual Control Modes Allowed.
C 4 Cascade Control Modes Allowed.
M.C 5 Also C.M. Manual/Cascade Control Modes Allowed.
A.C 6 Also C.A. Auto/Cascade Control Modes Allowed.
M.A.C 7 Also M.C.A, C.M.A, C.A.M, A.M.C, A.C.M. Auto/Manual/Cascade
Control Modes Allowed.
N/A 15 Configurator entry when setting mode model to SP/OP MODE only.
