An ethernet gateway adapter allows us to securely connect to your local area network. The gateway contains two isolated connections one for the local area network and one for the wide area network. This allows the end user to determine what we have access to. If the control system is on its own network, you would only see that control system, depending on the configuration of the local area network will change what we can access. Additionally, filters can be added to allow us to only access the IP address we have permission to see. If you have a firewall or network security in place, some coordination may be required to establish access.
Implementation
Remote access allows us to get online with the equipment and diagnose the issue without travel time. This can get production back up in the shortest time possible. Not every situation can be solved remotely but with on-site coordination many times it is the most effective to minimize down time.
