Basic Operation of Analog Input Processing
(1) Receiving analog input
The analog input unit receives analog input data from devices, such as laser analog sensors
and pressure sensors.
(2) Digital conversion processing
Analog input data received by the unit is converted into digital values in sequence
automatically in the unit. The converted digital value varies with the setting of the range.
(3) Storage of digital values
A user program is used to read converted digital values as data in the input relay area (WX).
The specified area number varies depending on the installation position of the unit.
