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
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.)
1
−15.00 to +115.00%
None (Calculation of square root, first-order lag, bias,
etc. is required by external blocks.)
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)
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.
1
−15.00 to +115.00%
Possible
Possible (0 to 115.00%/s)
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.
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.
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.
