1) The variable contains the status of the TCP/IP connection. TRUE means that the connection has been established and is active. FALSE means that the connection has not been established or has been already ended. If the client process is connected to D2000 Server via one or several active network components (gateway, router...), the status of the connection can, in the specific situations (the fault conditions, a physical cut-off of the wiring network), acquire this value belatedly by tens of seconds up to several minutes.
