MELSEC iQ F FX5U and MR-JE-_C CC-link

9 posts in this topic

I am new to PLC programing, I want to connect FX5U and MR-JE-_C via CC-link.

When I connect FX5U and MR-JE-_C directly everything works, but when I connect them in HUB (I need to use HUB because later I want to connect GOT2000) I am getting error 86.1(network communication error) on amplifier. Previously I set up IPs shown on pictures below, now sometimes works, sometime doesn't work and sometimes works for 30 seconds and I get same error. Did I miss something? I don't know what to try else.

oh sorry, Didn't read the post. I thought you neede info on how to do it.
 

Are you really using a HUB or is it a switch ? looks like the switch might have some function active which is blocking the network.
But first try the other ports on the hub/switch and also use other cables. wouldn't be the first time a defective cable is giving a problem.

I am using switch. Tried other ports, cables and other switch, nothing change. Connection with switch works when I write to PLC, only doesn't work with amplifier.

Strange, But if it work with a direct connection and you have tried other cables than the problem is in the switch. Does it have any security settings ?

Doesn't have any security settings. It's basic switch, like one on the picture
