Dear All,

I have 6 networked LOGO controllers (a combination of V8.3 and 8.4)

Controller 3 (v8.4) sends out a signal over the network to Controller 6 (v8.3) to switch an output Q2.

The Output Q2 on controller 6 has been switching on and off (once every 3-5mins) even though the input signal from controller 6 is continuiously on.

When testing this in 'online mode' (see attached screenshots) you can see the network signal from controller 3 as always red however the input signal to controller 6 switches between red and black.

I have completed some IT network tests over a 15min period and this shows zero packet loss

Please can anyone tell me why the networked input signal to controller 6 keeps switching on and off whilst the network signal from controller 3 is constantly on?

Many thanks in advance.

Just updating the firmware  - in your link i cannot see a checksum link to verify the software  - where can i do this?

Many thanks

Hi
