Hi Guys,
I'm trying to configure the Analog outputs (AO1,AO2) of TM172E28R expansion module to 4-20mA output (current modulation) but having problems with it.
I've configure both AO1 and AO2 as value '0' (current modulation) under Advanced Settings.
And then I do the full download. Everything complies fine with no error but when I test the outputs with a multimeter both outputs are showing around 40-50mA no matter what the programming value being 0-1000.
If I measure the AO3 and AO4 of the main controller, it correctly shows value within 4-20mA.
What am I doing wrong here?
