I have a brand new FX5U 32 MR/ES which has a built in AO and two AI.
I have enabled them all and AI works as expected. I can see values in SD6020 and SD6060 changing when I put a battery to it.
I can do a MOV to move the value from an AI to SD6180 which is the register for the AO. BUT the value on the analog out never changes. It is always 10V. Even if I have no program and only change the value in the watch window there is no change on the output.
Am I missing something? Do I have to set some register to activate an output voltage change? Or is it hardware related so I have to connect for example V- to 0v?
I have ONLY the L and N connected at the moment. Also S/S to 0V for a source input setting but even with this disconnected I see the same thing.
Or is the unit broken??
