A method for sorting alarm-messages of a plant having at least one alarm-area each having at least two plant-devices connected by at least one connection, wherein the at least one alarm-area is defined so that the plant-devices and the respective connection provide a directed graph, involves: providing at least one database containing alarm-data and topology-data; wherein the topology-data describe a directed graph having at least one connection with a related flow direction between the respective plant-devices of the respective assigned alarm-area; generating at least one partly complete first alarm-order of the alarm-messages of the at least one alarm-area by sorting the alarm-messages according to the flow direction of the directed graph.

A method for operating a plant apparatus having at least one first plant device and at least one second plant device separate from the first plant device, in which a first error message is generated by the first plant device and a second error message is generated by the second plant device, and the first error message and the second error message are transmitted to an electronic computing device of the plant apparatus for monitoring the plant apparatus, wherein at least one first procedural relevance is assigned to the first plant device and one second procedural relevance is assigned to the second plant device by the electronic computing device depending on a decision-making criterion and, depending on the respective assigned procedural relevance, a prioritization of the respective error messages is generated.

A computer-implemented method for determining an operational state of an industrial plant includes acquiring alarms raised within the plant and adding them to a pool of important alarms, determining whether a physical state of the plant indicated by a first alarm causes a second alarm or meets a predetermined state-dependent condition and, if so, moving the first alarm to a pool of informative alarms; and determining the operational state of the plant and/or a corrective action for improving this operational state based on the alarms in the pool of important alarms.

A graphical data priority representation for visualization and control of data processing in data processing systems such as industrial Internet of things systems is provided.

A message management facility is described herein that is hosted by a networked node, in a process control network environment, that is separate from a control processor. The message management facility routes a stream of messages received from the control processor to a set of destinations on a supervisory network. By interposing the message management facility on a node that is interposed, in a message steam, between alarm message sources (control processors) and alarm message sinks (workstations, printers, historians), a number of additional functions can be implemented to carry out a number of advanced functions. Examples of such functions include: table-based routing of a single alarm to a number of destinations on an application network, suppressing alarm showers by applying a criterion to received messages when shower conditions have been sensed, invoking commands based upon a configured category assigned to particular identified messages prior to delivery of the message to its final destination, and invoking actions in response to event/mode status changes (including re-prioritizing alarms).
