Codesys Neuron Digital Output/Relay Output issue
I have a Neuron m203 codesys setup. I am having trouble accessing the digital output and relay outputs on the device.
I cant seem to find any documentation on this.
I understand the the IO's are accessible via Modbus TCP (master ) and not gpio . I cant seem to figure out how to assign variables to the various outputs. I assumed I would be able to assign a variable to the I/o same as gpio outputs. Doesn't seem to be the case.
What the heck am I missing? Thanks in advance!

do you have the UniPi Neuron driver for CODESYS (https://store.codesys.com/unipi-neuron-for-codesys-sl.html)?
Hi Martin .
Yes I purchased ..installed .the licensed the neuron for codesys addon.
The outputs are assigned as for any IO device in CODESYS. Please check the CODESYS help for how to map IO.
There is also a UniPi Neuron library included in the package which makes it easier to handle the data types which span more than one register. Please see the help for the library in CODESYS.
