Both screen shots show the same error - the controller is not responding to the connection request or broadcasts from control builder.
If the controller responds to a ping request then usually the controller is OK and you have a network problem somewhere.
Is this a new problem on a previously working system ?
- What did you change ?
- Have you re-booted the engineering station ?
Is this a new controller or network that has never worked before ?
- Can you ping the controller from the Engineering station ?
- Have you got a router or firewall between the engineering station and the controller ?
- Is the engineering station connected directly to the Control Network
-- If no, have you got RNRP routing enabled on the Connectivity Server ?
In either case
- What RNRP errors can you see ?
-- Double Right Click the RNRP Icon on the task bar and run the diagnostic tests.
See the other comments in my original answer.
Both Control Builder and the OPC server use "MMS" to communicate with the PLC. If the PLC responds to a ping command then it has the correct IP address, but setup problems with the network route ( which is controlled by RNRP ) can mean that Control Builder cannot communicate with the PLC
Is the OPC server properly connected to the PLC ?
Where are you "pinging" the controller from ? Can you ping the controller from the Engineering Station ? Are you pinging the PLC from another computer in the network ?
You said "This PLC is Not on the network" in your first comment to my original reply. Was that a typing mistake?
If you can ping the controller but not download nor go online the controller's firmware has probably crashed or become stuck and you will need to reset the controller.
If you want an investigation/explanation to the problem, please contact your regional ABB support center. There may be logs in the controller that could explain the problem.
