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

The SIMATIC PCS 7 Maintenance Station provides maintenance engineers with comprehensive maintenance information on the system components (assets) of the plant. Starting from the overview display, maintenance engineers can navigate to the diagnostics displays of the subordinate hardware levels to obtain information on the diagnostics status of individual plant areas or components. If a fault is signaled in the overview display, the "Loop in alarm" function permits rapid switching to the diagnostics faceplate of the associated component.

The scope of information available depends on the individual possibilities of the asset, and is filtered according to the user's area of responsibility.

The following information is available, for example:

• Display of diagnostics status detected by the system
• Information on the component, such as process tag name, manufacturer or serial number
• Display of diagnostics messages of an individual component
• Visualization of the type and current state of the initiated maintenance measure

Information on mechanical assets

For mechanical assets without self-diagnostics (pumps, motors, etc.), the AssetMon function block can determine inadmissible operating states from various measured values and their deviations from a defined normal status. These are displayed as maintenance alarms on the SIMATIC PCS 7 Maintenance Station. AssetMon is able to process up to 3 analog values and up to 16 binary values.

In addition, AssetMon is suitable for implementation of:

• Individual diagnostics structures
• Project-specific diagnostics rules
• Condition monitoring functions

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.

• Device type information (electronic rating plate)
• 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 configuration changes)
• Information on changes (audit trail report)
• Parameter information

Visualization of the maintenance information

Uniform symbols for visualization of the maintenance status as well as operator prompting

The hierarchical structuring of information and the uniform symbols support the overview, facilitate orientation, and permit the maintenance engineer to rapidly access detailed information starting from the plant overview.

The symbol set defined for the plant asset management contains symbols which identify the diagnostic status of the devices/components, the relevance of the maintenance request, and the status of the maintenance measure.

Group displays in the plant overview visualize the diagnostics status of the subordinate structures/components according to a type of traffic light with red, yellow or green.

Appropriate to their significance, the components described per EDD can be marked as follows and also directly filtered using these features:

• Normal
• Important
• Safety Instrumented Function (SIF)

Diagnostics screens display the status of components and subordinate devices/components through standardized symbols with the following elements:

• Bitmap of component
• TAG identification of component
• Maintenance state display
• Group display for diagnostics status of subordinate components

Clicking an element in the symbol display either opens the subordinate hierarchy level or a component faceplate. The component faceplate offers various views of the associated component with additional device-specific information, e.g. an identification, message or maintenance view.
