Control module arrangement and compressed air maintenance unit

Abstract

The invention relates to a control module arrangement (20) for a compressed air maintenance unit (14) constructed like a battery and a compressed air maintenance unit (14), which has several maintenance modules (23-25) in a row one after the other, such as, e.g., pressure regulators, filters, oilers, or the like, wherein the control module arrangement has a bus communications means for communicating with the maintenance modules (23-25) via an internal bus (37) of the maintenance unit. The control module arrangement has a diagnostic means (53) for communicating with an input/output device (40) of the maintenance unit (14), wherein the input/output device has a connection means (43) for connecting at least one diagnostic sensor (44-46) separate from the maintenance unit and/or at least one pneumatic compressed air influencing actuator (47) 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 can receive diagnostic messages (48) from the one or more separate diagnostic sensors. The diagnostic means are constructed for generating diagnostic data (51) for a higher-order diagnostic device (18) for diagnosing at least one function of the compressed air maintenance unit with reference to diagnostic messages (48) of the one or more separate diagnostic sensors and/or the maintenance modules, so that the compressed air maintenance unit forms a diagnostic node.
