S103 Neuron Codesys GPIO mapping

[Sbr]

Hello,
I have a Neuron S103 Unipi . I can run de pi with codesys. But the hardware GPIO doesn't work? Where can I find the mapping? DI1 = GPI04?

Thx

Hello @sbr,
the IOs of the Neuron are not connected to the GPIOs. Instead, they are accessible via local ModbusTCP server (you can see the Modbus Registers Map)

Or better yet, check the official Neuron plugin for Codesys: https://store.codesys.com/unipi-neuron-for-codesys-sl.html?___store=en&___from_store=default

Best regards,
