Abstract:
1. A control module arrangement for a compressed air maintenance unit, the control module arrangement being adapted to be assembled in stacked arrangement with several maintenance modules of the maintenance unit in a row one after the other, wherein the control module arrangement has a bus communications means for communicating with the maintenance modules via an internal bus of the maintenance unit, wherein the control module arrangement further comprises a diagnostic means for communicating with an input/output device of the maintenance unit, wherein the input/output device has a connection means for connecting at least one diagnostic sensor separate from the maintenance unit and/or for connecting at least one pneumatic compressed air influencing actuator separate from the maintenance unit, wherein the control module arrangement can control the one or more compressed air influencing actuators via the input/output device and/or the control module arrangement can receive diagnostic messages from the one or more separate diagnostic sensors, and wherein the diagnostic means are constructed for generating diagnostic data for a higher-order diagnostic device for diagnosing at least one function of the compressed air maintenance unit with reference to diagnostic messages of the one or more separate diagnostic sensors and/or with reference to diagnostic messages of the maintenance modules, so that the compressed air maintenance unit forms a diagnostic node, and wherein the control module arrangement further comprises first communications means for communicating with a higher-order control device for controlling and/or monitoring the compressed air maintenance unit and second communications means for communicating with the higher-order diagnostic device, to which the diagnostic data can be output, wherein the arrangement operates the first communications means before the second communications means in order of priority.
