netPI Node-Red fieldbus node Error

[PersEE]

Hi there,

the netX fieldbus chip used on netPI RTE 3 monitors a software watchdog that needs to be triggered by Node-RED at least once in a second.

In case the Fieldbus node reports "Device not running" apparently the software watchdog was not triggered in time.

So the question is what else are you running on your netPI RTE 3 either within node-red or any other container that you have maybe deployed.

Please remember Node-RED is javascripting based and a periodically running single threaded application. If you would write a bad code like while(1) as and endless loop the whole node-red runtime would stand still.

Thx
Armin

Hello Armin,

Thank you for your reply.

Actually apart from the node-red-fieldbus, a container of codesys-basic is also deployed (in the host mode) but it uses only the standard Ethernet port.

I have tried to deactivate all the other flows but leave only the one in charge of the PROFINET communication, however, the error appears again.

I have no idea what is going on.

Thanks for your help.
