Operation Settings (For Server)

What is the system variable, #H_RemoteHMI_DisableConnections?

System Variable Name:#H_RemoteHMI_DisableConnections
System Variable Bit  Default OFF

Setup	Value
ON	Shutdown
OFF	Connection

If Server and Client are connected, when this bit turns on, connection is forced to shut down. If Server and Client are disconnected, when this bit is on, Client cannot connect to Server.

Note:
This system variable cannot be used in the offline mode.
When you want to force connection to shut down, you need to turn on the bit of the system variable before entering offline. The system variable turns off after entering offline.
When you transfer a screen or enter offline with the system variable ON (in a state of connection disabled) and after that you return to online, the system variable is off (in a state of connection enabled).

If Server and Client are connected, when this bit turns on and Client connects to the Server with this bit on, the following message is displayed on the Client's side.
"Pro-face Remote HMI communication is currently unavailable on the server. Please try again later."

Supplement:
You can use this function to avoid operation by Client while you make important adjustments on Server at the site.

You can use it when you need to have the initiative of operations on Server.
