ABSTRACT:
A current generator that provides a first current level to read a configuration parameter of a field device. The current generator also provides a second current level. The first current level is lower in amperage than the second current level. The first current level does not operate the field device. The second current level operates the field device. A current sensor is connected in circuit with the field device. The current sensor reads the configuration parameter associated with the first current level. A method is provided that creates a current that reads a configuration parameter. The current has less than a minimum amplitude to operate necessary to operate a field device. The configuration parameter is read from the field device through employment of the current. The field device is configured through employment of the configuration parameter.
