Description of Operation Section 3-2
Operation Overview During Loop Controller operation, pseudo-inputs (fixed values) can be
assigned to the PV for the Control Block (e.g., Basic PID) from the CX-Pro-
cess Tool or SCADA Software/PT during Loop Controller operation.
Even if there is no actual sensor externally connected, the operation (e.g.,
alarm operation) for the entire function block in response to the PV value in
the Control Block can be easily confirmed. If a Sensor error occurs, pseudo-
inputs can be assigned to enable easy sensor replacement during operation.
Note This function eliminates the previous need for function block programming
that assigns pseudo-inputs using ITEM write blocks for variables.
Operations in Calibration
Mode
• Use either of the following methods to switch to calibration mode.
a. Using CX-Process Tool: Use the wireless debugging setting operation
from the operation confirmation window in the block diagram.
b. Using SCADA Software/PT, etc. (HMI interface): Turn ON the Calibra-
tion Mode Selection Bit in the HMI data area.
• After switching to calibration mode, the actual input specified in ITEM 006
(PV source designation) will be tracked in ITEM 007 (PV input or P1
input). (In other words, the PV will not be changed merely by switching to
calibration mode and will be changed only after the PV input value in
ITEM 007 is changed.)
• During calibration mode, ITEM 007 (PV input or P1 input) can be changed
from the CX-Process Tool, or SCADA Software/PT, etc. (HMI interface).
• The actual PV input in the ITEM 006 (PV source designation) will be
reflected in the actual PV input monitoring area (500 words from
EM
@_29020) in the HMI data area (in all modes including calibration
mode).
