Hi.

I have a problem with two logos that are connected through a shielded siemens ethernet cable ( 2meters long)

Sometimes the "Lan" light on the two logos switches of and then comes back again after 1 second.

And this problem occurs when i run the crane were the logo is in.

It seems that when the Logo and the slave is working the Lan is reset, and its just somethimes .

Hope that someone has some answers thx.

the earthcable is connected on both logos =/

i might add that the "Lan" light goes completly dark for 1 sec.

“The LAN led must always lit, green or orange. If the led isn't lit, then have is no ethernet cable plugged or the LOGO! nhas no power supply.”

Yes i know , and the power is never lost , is just the lan that is lost sometimes..

qwazee

1) Are you able to connect the PC to the LOGO! using that cable?
    Test both LOGO! units for its PC link.

2) What is the IP addresses of each of the LOGO! units?

3) How are the LOGO! units currently programmed?

 1. Yes there is no problem , and the units work just fine most of the time , it’s just sometimes the lan is lost..

2. 192.168.000.002 and 192.168.000.003.

3. Not sure what u mean , it is a master and a slave , and the master has 2 expansions and the slave has 2 expansions.

If only the connection lost some times, then only the LAN led changes the color between green and orange. But one of this both colors is on.

 Okey, I see what you mean , but if I unplug the lan cable the lan light is black ( off).

maybe there is a very quick loss of voltage supply to the logo unit 🧐
