Universal Robots connection to Anybus-S (Fronius welder)

Hello,
this question about connection UR10 to Fronius TransSynergic 4000 via AB Ethernet IP module.
Do someone has an expirience in it? We already make the connection with MODBUS, but can’t reach list of signals. Have a version that we should use something controller like a bridge between robot and welder. Or use a specialize software filter (finder?) what can give us list of signals to control.
Greetings for any help!
