Basics
EasyAccess 2.0 access technology is quite different from traditional way of remote access method. Here are some notable points:
| Traditional remote connection (blue links) | EasyAccess 2.0 (green dotted links) |
|---|---|
| Connection traffic must pass through a number of firewalls, which means there are layers of network settings. | PC and HMI both connect to a dedicated VPN server through which data are exchanged, or by P2P. |
| Network/Router setting is mandatory; therefore, coordination with the IT department is crucial. | No additional network setting is required. |
| For one WAN IP, only one device can be connected. | For one WAN IP, multiple devices can be connected. |
| For a device behind two or more routers, connection might not be possible. | Being behind several routers does not affect EasyAccess 2.0 connectivity at all. |

Activation
While selected models come with built-in EasyAccess 2.0 license, most do not, and must be activated in order to use the feature. A purchased license can be used to activate any one of the supported models; however, once an HMI has been activated, its license cannot be transferred to another HMI.
