Sensor inputs are blinking in Tia portal

All the sensors giving me a blinking result in tia portal when they are “true” in factory I/O, even when I force the sensor…
somebody help me.

Hi @phungtheduy123!

This issue usually happens because the inputs’ addresses are being used by both Factory I/O and the PLC you are using, which causes them to be overwritten.
We have a post explaining this in more detail. You can find it here: Siemens: inputs not working

I hope this helps
