ABSTRACT:
A DCS protocol message addressed to a remote DCS station is generated at a local distributed control system (DCS). The DCS protocol message is received at a local tunneling device. The local tunneling device packages the DCS protocol message into a SCADA protocol message. The SCADA protocol message is transmitted from the local tunneling device to a remote tunneling device. The remote tunneling device receives the SCADA protocol message. The SCADA protocol message is unpackaged into a DCS protocol message at the remote tunneling device, and the DCS protocol message is placed on to a remote DCS such that it flows to the remote station. The DCS protocol message is received at the remote station.
