1. An apparatus, comprising:

  • a base comprising;

    a first physical interface to be communicatively coupled to one of a first field device in a process control system or a second field device in the process control system; and

    a second physical interface to be communicatively coupled to a controller in the process control system via a bus; and

    a module to be removably attached to the base, the module to communicate with the first field device using a first communication protocol when the first physical interface is communicatively coupled to the first field device, the module to communicate with the second field device using a second communication protocol when the first physical interface is communicatively coupled to the second field device, the module to communicate with the controller via the bus using a third communication protocol, the third communication protocol different from the first and second communication protocols.
