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 different than the first 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.
