The continuity operation guarantee of an industry presupposes the existence of, at least, a contingency plan for automation, which is, usually managed by Maintenance Sector. This paper proposes the development of a cloud computing based system for contingency management automation applicable in industries of all sizes with some automated bases. The implementation of such a system implies the following steps: register the unity automation, create a database from the register, physically identify automation items, establish and perform the periodic updating of the contingency plan. The result is a list containing all electronic modules which are linked to the unity automation that are the basis for structuring a contingency plan. Item information as physical address, the process to which it is linked, description, reference, the contingency criteria, parameterization, programming, cost, and the management reports are some examples of data that can be extracted of this hardware and software inventory. One of the benefits of adopting a computerized system for automation contingency management is that the Maintenance Sector can map the entire factory. This allows a rapid decision-making in the case of imminent stop in the process due to electronic modules, ensuring the continuity of operation.
