7-9-2 Overview
This unit executes high-speed input of analog input signals (A/D conversion
time: 50
m
s).
One of five signal types for analog inputs,
-
10 to +10 V, 0 to 10 V, 0 to 5 V, 1 to
5 V, and 4 to 20 mA can be selected.
Analog input values are stored in AR 02 of the auxiliary memory bits on the
unit. An analog input value at END refresh is stored as the input value. Addi-
tionally, analog input values can be compensated.
Using PRV instruction enables the unit to acquire the latest analog input value
through immediate refresh method. With this function, inputting analog signals
from a pressure sensor, position meter, or sensors that require high-speed
input processing such as a displacement sensor/end-measuring sensor real-
izes pressure control, tension control, or control involving mechanical mea-
surement (distortion/thickness/length) with comparatively lower cost and
ease.
Note The analog input responsiveness of the CS1W-HCA12-V1 has been set com-
paratively higher for speeding up the processing. Because of this, the distor-
tion of input signals caused by external disturbance may be detected
sometimes. When using the unit in a place with a lot of noise, make sure to
take measures against it. In addition, when using the analog input value of the
unit, take measures against it also in the ladder program by executing the
AVG instruction with END refresh method to provide a filtering process, etc.
