Intel GPIO nodes: only DI4 works

Hi, I installed image v2.6.1 and I am trying to use the Intel GPIO nodes.

I tested with the Intel user button and user LED nodes and it works correctly but I  when I try the digital inputs DI0-DI4 only DI4 works. All DI have the same settings.

Is there a problem with the Intel GPIO nodes or there is something I am not doing correctly?

Hi AutoGen_263002,

I have not tried on the 2.6.1 but on all my IoT devices, running on the 2.6.0 (More than 50 devices), I am using the nodes available in the below post, and all the DI work perfectly.

Give it a try with your image 2.6.1 and let us know.

Hi, Here is the solution:

DI0 on IOT2040 = D12 in Node-Red

DI1 on IOT2040 = D11 in Node-Red

DI2 on IOT2040= D10 in Nde-Red

DI3 on IOT2040= D9 in Node-Red

DI4 on IOT2040= D4 in Node-Red

That explains why only DI4 was working

By the way the DI Intel node works fine.

The user application port for each of the inputs & outputs are clearly mentioned in the Siemens documentation of the Input/Output modules. You might have missed that.

That applies not only to Node-RED. That will be the same for all applications using those modules as they are the physical pins where the AI, DI, DO are connected.
Whether it is an Arduino sketch, a python application, or anything else the address of your inputs and outputs will be the same.

I am adding the rest of the reference for the other ports of the Input/Output module.

In case you are using the Sink/Source module next time, that has 10 DI the address will be different.
