A system for transferring a signal between a field device and a control system component includes a field linking unit and a system gateway. The field linking unit is electrically coupled to a field device, and a signal is transferred between the two using a first protocol. The system gateway is electrically connected to a control system component, and the signal is transferred between the two using a second protocol. The field linking unit and the system gateway communicate wirelessly. One of the field linking unit and the system gateway may encrypt the signal before sending, and the other may decrypt the signal upon receipt. The system may also include at least one intermediate node, and the field linking unit and the system gateway may communicate wirelessly via the intermediate node(s).

What is claimed is: 1. A communication system comprising:a field linking unit electrically coupled to a field device and operable to transfer a plurality of signals between the field device and the field linking unit using a first protocol;a first system gateway electrically coupled to a first control system component via a first communication link; anda second system gateway coupled to the first system gateway via a second communication link, electrically coupled to a second control system component via a third communication link, and operable to transfer at least some of the plurality of signals between the second system gateway and the second control system component using a second protocol via the third communication link, wherein the first communication link is physically separate from the third communication link;wherein:the field linking unit and the first system gateway are operable to communicate wirelessly,the first system gateway is operable to:transfer a first signal of the plurality of signals to the first control system component via the first communication link based on a first indication that the first signal is required by the first control system component, andforward a second signal of the plurality of signals to the second system gateway via the second communication link based on a second indication in the second signal that the second signal is required by the second control system component, andthe first protocol and the second protocol are related protocols.
