Process control system devices with dual hardwired and wireless communication ports
First Claim
1. A field device for use in a process control system within a process control environment, comprising:
- a microprocessor-based communication unit of the field device for generating or receiving communication signals;
a first communication port of the field device connected to a hard-wired communication link for providing communications to or from the communication unit via the hard-wired communication link; and
a second communication port of the field device connected to a radio frequency wireless transceiver to provide wireless communications to or from the communication unit via the wireless transceiver.

Abstract
Field devices or other devices within a process control system are provided with both hardwired and wireless communication ports to enable communications to be performed within the process control system using one or both of hardwired and wireless communications. In particular, a field device for use in a process control system within a process control environment includes a microprocessor-based communication unit adapted to generate or receive communication signals, a first communication port adapted to be connected to a hardwired communication link for providing communications to or from the communication unit via the hardwired communication link and a second communication port adapted to be connected to a wireless transceiver to provide wireless communications to or from the communication unit via the wireless transceiver.
