Hi Flex727,
Thanks for your suggestions. In fact, those resouces are very helpful but I don't manage to see why my analog output doesn't work..
I've a module I/0 snap-in E3XB with 12 bits analog outputs. To test my analog output, I've created a new project where analog output 0 (0-10V) is associated to MI 0.
If I set MI 0 to 4095, I should have 10V on analog output 0 but it's not the case.
As you said me before, I don't use immediate "Write Analog Ouput".
