Asset Management

Maintenance station

■Function

Diagnostics message of a component in the faceplate view "Identity"

The maintenance station provides comprehensive maintenance information for the system components of the plant (assets). In order to obtain information on the diagnostics status of individual plant areas or components, maintenance engineers can change from the overview display to the respective diagnostics display of the subordinate hardware level. If a fault is signaled in the overview display, the "loop in alarm" function permits rapid switching to the diagnostics faceplate of the associated compo- nent.

The scope of information available depends on the individual

8possibilities of the asset, and is filtered according to the user’s area of responsibility.

The following information is available:

•Display of diagnostics status determined by the system

•Information on components such as tag name, vendor or se- rial number

Enhanced information for assets according to IEC 61804-2

Further information can be called for assets described by the electronic device description (EDD) according to IEC 61804-2. This information is automatically read out of the components and made available by SIMATIC PDM in the background.

•Detailed diagnostics information

-Device-specific information from the vendor

-Information on fault diagnostics and troubleshooting

-Additional documentation

•Results of internal condition monitoring functions

•Status information (e.g. local operation, local configuration changes)

•Display of modification logbook (audit trail) of the component with all entries on the persons, times and types of operator in- tervention on the component

•Parameter view of the assets (display of parameters saved in the component and in the project; if required, also differences between them)

Information on passive or indirect assets

For passive or indirect assets (pumps, motors, control loops etc.) without self-diagnostics, you can use the programmable logic block AssetMon to derive inadmissible operating states from various measured values and their deviations from a de- fined normal status and to display them as a maintenance alarm on the maintenance station. AssetMon is able to process up to 3 analog values and up to 16 binary values.

With the aid of the AssetMon, individual diagnostics structures, project-specific diagnostics rules and condition monitoring functions can also be implemented.

Uniform symbols for visualization of the maintenance status and for HMI on the maintenance station

A significant feature with visualization of the access manage- ment functionality is the uniform symbols and texts for displaying the statuses of all assets, i.e. for operator stations as well as for network components, controllers or field devices. The asset faceplates are also uniform. The amount of information dis- played depends on the intelligence of the respective compo- nent.
