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 

possibilities 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

• Display of diagnostics messages of a component
• Visualization of type and current state of initiated maintenance 

measure

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.

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)

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.
