1-3-4 Outline of PID Block Specifications
This item mainly describes an outline of the PID block specifications.
In the Basic PID block (Block Model 011) and Advanced PID block (Block
Model 012), the functions are set to ON and OFF. For actual details on each
ITEM setting, see the descriptions for each block.
❍: supported, ×: not supported
Item Description Basic
PID
Ad-
vanced
PID
Operation cycle Depends on operation cycle set for each block (0.01,
0.02, 0.05, 0.1, 0.2, 0.5, 1, or 2 s)
(0.01, 0.02, and 0.05 s are not supported for the
CS1D-LCB05D.)
❍❍
PV (Process Variable)
Input
Number of points 1
❍❍
Input Range −15.00 to +115.00%
Operation function None (Calculation of square root, first-order lag, bias,
etc. is required by external blocks.)
Sampling cycle According to the specified operation cycle of this block
(one of 0.1, 0.2. 0.5, 1, 2 seconds or 1 to 128 sec-
onds)
PV error input When the PV error contact turns ON, the Loop Con-
troller is forced to enter the Manual mode, and the MV
value active at that moment is held. At the same time,
the PV error is transferred to the SCADA software or
other device.
SP (Set Point) Number of points 1
❍❍
Setting range −15.00 to +115.00%
Remote/Local switch-
ing
Possible
SP rate-of-change
limiter
Possible (0 to 115.00%/s)
× ❍
PV tracking Match the SP (Set Point) to the PV (Process Variable)
if the Loop Controller is in the Local and Manual
modes when PV tracking is set to ON.
❍❍
Bumpless processing
between primary/sec-
ondary loops
When the local node is performing cascade control as
the secondary controller, processing is performed on
the MV of the primary controller to be input.
Deviation PV compensation Arithmetic operation (addition, subtraction, substitu-
tion) is performed on the PV signals to be input to the
PID control section when the PV compensation input
switch is ON.
