A human machine interface (HMI) configured to provide visualizations of one or more device elements that correspond to one or more components in an industrial automation system on an HMI screen. The HMI includes computer-executable instructions stored on a tangible machine-readable medium configured to determine whether at least one of the device elements is associated with an error and modify at least one graphic that corresponds to the at least one of the device elements when the one of the device elements is associated with the error.

A transmission device includes a transmission processing circuitry configured to transmit and receive signals to and from another transmission device through a transmission path, a first memory, a first processor coupled to the first memory, configured to perform monitoring control of the transmission processing circuitry, a second memory, and a second processor coupled to the second memory, configured to perform monitoring control of the transmission processing circuitry on behalf of the first processor when a failure occurs in the first processor, wherein when a failure occurs in a monitoring control system that performs monitoring control of the other transmission device, the second processor performs monitoring control of the other transmission device by transmitting and receiving control signals to and from the other transmission device.

A method for monitoring an installation having a networked topology, wherein measured values characterizing a state of the installation at the measuring point in question are captured and transmitted to a control-center apparatus, which determines state values indicating a state of the installation. The state values are used to show the state of the installation and they are compared with state threshold values that bound an operating range of the installation. A graphical representation is produced only for those state values for which a past or imminent violation of the associated state threshold value is detected. A visual display of a network topology is displayed on a display. Location information indicating the position of the state value in question in the installation is associated with each of the state values, and each representation is displayed at the point corresponding to the position of the representation in the installation.
