Analog output overwritten

Dear PLCnext Forum,

I am having trouble with an AXC F 1152 in combination with an AXL SE AO4 I 4-20 and an AXL SE AI4 I 4-20. I want to write and read directly the analoge values. This means: I want to write for example 15 mA and then read with the AXL SE AI4 I 4-20. I use both port 1 on the analog input and output. I connect the plus of the output to the plus of the input, same for the minus.

I can measure that something is happening, but I have the following problem: My variable that I use to write a value to the analog output is somehow overwritten.

See Figure 1, where I show how I compute the AO0_FBOut_TEST.
{B9034AB2-65BA-4D96-B2E0-B45D04456668}.pngThis seems to work well, but, now I go to the actual analog ouput: here I see the following:
{D96B01FC-D64E-41C7-8BED-BF6F36535D1B}.pngHas someone experience with this or can someone help me to get into the right direction to solve this?

Thank you very much in advance!

This is btw with the boolean for the output of the analog smart element as TRUE.

I think the analog output variable should be connected to the OUTO01 process data item on the analog output card, not the IN01 data item.

Make sure your variable (raw analog) is local not external, and to change the value just double click on it and change it, do not force it.
