METHODS AND APPARATUS TO IDENTIFY A COMMUNICATION PROTOCOL BEING USED IN A PROCESS CONTROL SYSTEM
First Claim
1. An apparatus, comprising:
- 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.

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.

8. A method, comprising:
-
receiving a first signal at a port of a process control device; receiving a second signal at the port; comparing the first signal to reference communication protocols to identify the first signal as being associated with a first communication protocol; comparing 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; and processing the first signal based on the first communication protocol and the second signal based on the second communication protocol. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A tangible computer readable storage medium comprising instructions which, when executed, cause a machine to at least:
-
compare a first signal to reference communication protocols to identify the first signal as being associated with a first communication protocol, the first signal received at a port of a process control device; compare the second signal to the reference communication protocols to identify the second signal as being associated with a second communication protocol, the second signal received at the port, the first communication protocol being different than the second communication protocol; and process the first signal based on the first communication protocol and the second signal based on the second communication protocol. - View Dependent Claims (16, 17, 18, 19, 20)
