The general request causes the driver to connect to the Runtime. The connection will be established in sectors.
If the connection cannot be established, there will be a negative response to the general request. If there is an active general request for the sector, it will be terminated and a warning message will be logged.
Value changes for IOs that have already sent their values to the master will be buffered as long as the general request is active.
During a project reload, it is not possible to connect to the RT. The general request will fail in this case.
