Issue:
Looking for an internal system variable that will reveal the status of the Ethernet port of an HMIST6
Product Line:
Harmony HMI, HMIST6, HMISTM6, EcoStruxure Operator Terminal Expert
Resolution:
Currently in EcoStruxure Operator Terminal Expert V3.2 SP1, there is no way to determine the status of the Ethernet port by the means of a built-in Internal System Variable.
As a workaround, we could monitor the Quality property of an External Variable. Here are the different states that the Quality property could be in:
Here is an example script that will write the Quality property to a variable named "StatusVar". Note Var1 is our external variable.

| Value | Description |
| 0, 4 | Access to device address and device address value is normal. |
| 1, 3, 5, 7 | Cannot access the device address. |
| 8, 12 | Device address value is invalid. |
| 9, 13, 15 | You cannot access the device address. Also, the device address value can be invalid. |
| 2, 6, 10, 11, 14 | Not in use |
