4. Click the Transfer [PC to Unit] Button to download the data, and then click
the Reset Button to reset the Unit.
5. Click the OK Button and exit the window.
Note 1. The 1/100 Display Mode must be enabled by setting the connection path
with the CX-Integrator.
If the Normal Display Mode is selected for the I/O data from the CX-Inte-
grator, the temperature data will change to 0.
2. In 1/100 Display Mode, the temperature data will be converted to two dec-
imal places even though the actual resolution is not 0.01
°
C (or
°
F). Conse-
quently, the display for temperatures in 0.1
°
C/
°
F or 0.01
°
C/
°
F ranges may
jump back and forth between values. Treat any values displayed in Normal
Display Mode beyond the specified input resolution as reference data.
7-2 Overview of Temperature Input Units
7-2-1 Math Operations and Processing Input Data
Performing Math Operations on Input Data
The following math operations can be performed on external temperature
input values.
• Scaling to user-specified industrial units
• Moving average processing
Processed data can be allocated as I/O in the Master Unit.
The following math operations can be performed on temperature input values
that have undergone the above processing.
• Peak/hold operation
• Top/valley operation
• Rate of change calculations
• Cumulative operation
The values after processing are called peak value, bottom value, top value,
valley value, rate of change, and cumulated value.
Math operations are performed according to the following flowchart.
