Connection error variable.

Connection error variable.

Hello, I have two RTU connected to one driver via redundancy. So if I lose connection to RTU1 then RTU2 take over.
But I want an alarm in the HMI that driver lost the communication to a specific RTU.
Before I run Sicam230 and AK-Driver then I just made two internal variables whit the name _AK_LAN001 and _AK_LAN002.
Then I got a specific alarm if any RTU connection did go down.

But how do I do in Zebnon 8.20 I was looking at variable ConnectionStates: But what see if the driver connection is ok or not. Not if I have a faild connection to a specific RTU.

Variable:ConnectionStates
STRING
61
Internal connection status of the driver to the PLC.
Connection statuses:
0: Connection OK
1: Connection failure
2: Connection simulated
