Overview of Temperature Input Units
Section 7-2
Selecting Allocation Data
After performing math operations, select the data to be allocated to I/O in the
Master Unit from the following six values: temperature input value, peak value,
bottom value, top value, valley value, and rate of change. The selected data
will be Temperature Data 1, and can be allocated in the Master Unit alone or
in combination with Status Flags. The data is selected using the CX-Integrator
or explicit messages.
Comparison with four alarm set values, HH, H, L, and LL can be performed for
Temperature Data 1. This is called the comparator function.
Flow of Data in
Temperature Input Units In a Temperature Input Unit, it is possible to switch the display mode of the
data selected from the six values. The Display Mode can be the Normal Dis-
play Mode or the 1/100 Display Mode. The data can be allocated in either
mode for Temperature Data 1.
