Checking preset value
If you transmit a preset value to the A3M60 Basic, then in the
Monitor/Modify Variables
dialog box for the STEP7 you can see the PEW (peripheral input word) and PAW (peripheral
output word).
00000024h is transmitted from the encoder to the PLC as the position.
00000010h is transmitted from the PLC to the encoder as the preset.
Bit 31 is set to 0, as a result the preset value is not applied.
80000010h is transmitted from the PLC to the encoder as the preset.
Bit 31 is set to 1, i.e. a transition from 0 to 1 occurs, the preset value 10h is applied.
00000010h is transmitted from the encoder to the PLC as the position.
