To provide greater efficiency in connecting and establishing communicational equipment, the communicational system type can be automatically detected and the communicational equipment can configure itself in accordance with the automatically detected communicational type. Additionally, to accommodate dynamic reconfiguration, or changes to the communicational type after an initial configuration, the communicational type can be automatically monitored and the communicationally equipment automatically reconfigured if changes are detected. Different sets of comparator circuitry can be utilized to compare the voltages observed at known inputs to known thresholds of different communicational types to automatically detect the communicational type being utilized by existing equipment to which the newly-connected equipment is communicationally coupled. For efficiency, already existing circuitry for converting electrical voltages into digital data can be leveraged to monitor and automatically detect the communicational type being utilized.

Automated detection of communicational system type

In a nuclear process control system, a priority logic module (PLM) is provided. The priority logic module comprises a plurality of input ports, each input port associated with one of a plurality of priorities, a plurality of output ports, and a test mode select port associated with a test mode select signal. The test mode select signal selects one of a normal mode or test mode, each mode being associated with matching signals received by the input ports to signals sent by the output ports. The priority logic module further comprises a configurable priority logic circuit, wherein the priority logic circuit maps one of the input ports to one of the output ports.
