Task
Solution
Sample Configuration
JetSym STX-Program
Variable Declaration
Jetter AG
The values at the analog outputs of a JX3-AO4 module are to be recorded in
intervals of 20 ms. After this, the values are stored to the registers of the
controller.
The oscilloscope function of the JX3-AO4 module records the values. After
that, it reads the application program to the controller.
This example is based on the following configuration:
