ABSTRACT:
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).
