On a client station at startup if the server is not here.
All the external variables will generate an error in the event viewer and their status will be NS COM LAN.
On a passive station in an association if the active station doesn't know the existence of the variables.

Is it possible to see this status if there is a time out during variables subscription at startup ?

Yes the status is NS COM LAN if there is a time out during variables subscription

Also for information you can change the time-out value or bypass it.
Could be useful if, because of this time-out, the starting time is very long...
In options.dat you could see the following block for each data source
[WATCHVARS]
PacketSize=500
TimeoutEnable=1
Timeout=20
EXT: External variables (used for a client)
EQT: Equipment (used on server side)
etc...
TimeoutEnable=1
- 0: Disable time-out
- 1: Activate time-out
Timeout=20
Time-out is 20s if activated
Take care, the EXT time-out is not the time-out between the server and the client. It's more an internal time-out between PcVue processes... But, anyway, if you disable it the result will be: Startup very fast!

The time out is between the send PacketSize of subscription and the subscription response on at least each subscription.
