<p>The module (6) has communication units communicating with central units (2a, 2b) by fieldbuses (5a, 5b), respectively. A processing unit i.e. microprocessor, establishes selection of a primary central unit from the central units by taking into account a functioning state of each fieldbus, a functioning state of each central unit and consultation of information provided by the central units. The processing unit controls outputs of the module according to information received from the primary central unit. An independent claim is also included for a modular programmable industrial automaton comprising a sensor and/or an actuator.</p> |
