We have introduced an automatic log-off function, making it possible for the administrator of the IGSS network to set a disconnect from server for a passive operator station. The setting is found in the System Configuration module and is selected for each operator station in the network. This is to avoid the situation where an operator logging on from his home is not permitted to do so because there are no more operator licenses available. A colleague at the plant forgot to log off before leaving the plant, and this is the license needed by the remote operator. With the new function, the idle license at the plant can be released for use by, in this case, the remote operator.
The network administrator determines the operator station disconnect settings.
