Is it possible to monitor the Ethernet Port Status of an HMIST6 in EcoStruxure Operator Terminal Expert

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:

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

Here is an example script that will write the Quality property to a variable named "StatusVar". Note Var1 is our external variable.
