Analog outputs represent the output terminals like relay coils, inverted outputs and float outputs on a LOGO!.
To change an output in your LAD circuit program, double-click the corresponding block to open a dialog in which you can assign various functions to the output.
If you connect a special function that has an analog output to a real analog output, then note that the analog output can only process values from 0 to 1000, 0 to 4095 or 0 to 10000 (depending on the analog resolution you set in the I/O settings).
