Controller is not pinging from Engineering station, But pinging from Connectivity server..?
Controller is not pinging from Engineering station, But pinging from Connectivity server.
TCP/IP forward is enabled.
Controller IP Series-172.16.80.XX
Plant Network Series -172.16.4.XX
Controller -AC 800M PM866
800xA version- 800xA 5.1 Rev E FP4
Yes, you answer yourself !
If you look, the controller is 172.16.80.xx, which is usually Control Network. So you will need to be in that network, to be able to ping it. Connect servers are usually there too, but workplaces, aspect servers and second network card of connect servers are in 172.16.4.xx which is Client Network
Since you enabled TCP/IP forwarding controller should be able to ping from any node in system irrespective if node has connection to control network or not.
However if it is a fresh controller you may need to download to controller from a connectivity server and after that you could do it from any node.
