ADS disconnects roughly every 15s #47

henne959 commented 3 years ago

I'm running it on a Raspberry Pi 3b+ with just a few reads and a dashboard with buttons to write BOOLs. The Pi is connected via WLAN to the home network where the PLC CX8190 (TwinCat 3.1.4321) is connected via LAN.

Every ~15s the connectStateText is changing from connected --> disconnected --> connected. The adsStateText changes from run --> invalid --> run

The disconnected state lasts for about 5s. I don't get an other error. The only cyclic read is with the ADS System node.

What can cause this?

It looks like the Net-ID and IP are not stored correctly in the PLC.

It's well explained here. https://github.com/dkleber89/ioBroker.beckhoff Since it uses the common API, the process is identical.

Sorry for the late reply!

I forgot to check the "Symbole erzeugen" property.

Now it runs smoothly, thanks!
