Abstract:
Methods and apparatus to identify a communication protocol being used in a process control system are disclosed. An example apparatus includes a process control device including a port to be in communication with a bus, the process control device to receive a first signal at the port and a second signal at the port, the process control device including a protocol detector to compare the first signal to reference communication protocols to identify the first signal as being associated with a first communication protocol, the protocol detector to compare the second signal to the reference communication protocols to identify the second signal as being associated with a second communication protocol, the first communication protocol being different than the second communication protocol, the processor to process the first signal based on the first communication protocol and the second signal based on the second communication protocol.
