A visualization device for a production installation , which contains at least one cyclically operating shaping machine for visualizing a process state of the production installation which contains: - a display device for displaying a visualization program stored in a memory device - a computing unit , which is in connection with the display device and/or with the memory device by way of a data connection or is configured such that it can be brought into data connection with the display device and/or the memory device and which is configured to ascertain continuously or in time-discrete relationship the value of a plurality of selected process variables of the production installation and to compare the respective current value of each selected process variable or a variable derived therefrom to one or more reference values and to determine a deviation or a rate of change wherein it is preferably provided that the visualization program is designed to visualize by the display device each selected process variable with respect to its value and/or the deviations or rates of change determined by the computing unit , characterized in that - various logical groups can be visualized by means of the visualization program and that each selected process variable is associated with at least one logical group, wherein - logical groups are arranged in at least two hierarchy levels in such a way that at least one logical group of a lower hierarchy level is associated with another logical group of a higher hierarchy level, and - for each logical group a state of the logical group can be visualized by means of a display device on the basis of the process variables associated with said logical group. - a display device for displaying a visualization program stored in a memory device - a computing unit , which is in connection with the display device and/or with the memory device by way of a data connection or is configured such that it can be brought into data connection with the display device and/or the memory device and which is configured to ascertain continuously or in time-discrete relationship the value of a plurality of selected process variables of the production installation and to compare the respective current value of each selected process variable or a variable derived therefrom to one or more reference values and to determine a deviation or a rate of change wherein it is preferably provided that the visualization program is designed to visualize by the display device each selected process variable with respect to its value and/or the deviations or rates of change determined by the computing unit , characterized in that - various logical groups can be visualized by means of the visualization program and that each selected process variable is associated with at least one logical group, wherein - logical groups are arranged in at least two hierarchy levels in such a way that at least one logical group of a lower hierarchy level is associated with another logical group of a higher hierarchy level, and - for each logical group a state of the logical group can be visualized by means of a display device on the basis of the process variables associated with said logical group. - various logical groups can be visualized by means of the visualization program and that each selected process variable is associated with at least one logical group, wherein - logical groups are arranged in at least two hierarchy levels in such a way that at least one logical group of a lower hierarchy level is associated with another logical group of a higher hierarchy level, and - for each logical group a state of the logical group can be visualized by means of a display device on the basis of the process variables associated with said logical group. <EOS>
