BUILT-IN ANALOG FUNCTION
The analog I/O terminal functions built into the FX5U CPU module are explained below.
25.1

Function Outline

There are two lines of analog voltage input and one line of analog voltage output built into the FX5U CPU module.
Functions must be configured using parameters to use the built-in analog circuits.
The values resulting from A/D conversion by the FX5U CPU module are automatically written in special registers for each
channel.
By setting values into the special registers in the FX5U CPU module, the signal after D/A conversion is automatically output.
For details on the function, refer to the following manual.
