Abstract: An interaction module for a switch cabinet-free automation system of an industrial plant. The interaction module includes a housing and a plug connection component for the electrical and/or mechanical connection to a base of the switch cabinet-free automation system. Furthermore, the interaction module has an output element which is arranged in or on the housing and is configured to output an optical and/or acoustic signal which signals a status of the industrial plant. Alternatively or additionally, the interaction module has an input element which is arranged in or on the housing and via which an input for controlling the industrial plant can be made. Furthermore, a switch cabinet-free automation system is described.
