Hi there,

I want to know if it's possible to control the outputs of an logo 8 with an IOT2020 nodered?
Because I already use third party software for my home automation installation, I want to be able to control an logo 8 by IOT2020 with nodered.

Hi,

yes this is possible with the s7-node from node-red.

There are several entries about this topic. Please check:

There is described what you have to address in the node to read/write the specific LOGO VMs.

Best regards!
