SIMATIC PCS 7 Maintenance Station
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 devia-
tions from a defined normal status. These are displayed as main-
tenance 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 sym-
bols 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/com-
ponents, the relevance of the maintenance request, and the sta-
tus 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.
In line with their signficance, the components described with a
device description package in SIMATIC PDM can be marked as
follows and also directly filtered using these features:
• Normal
• Important
•
Safety Instrumented Function (SIF)
•
Device checked
•
Project-specific write protection
Diagnostics screens display the status of components and sub-
ordinate 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 compo-
nents
Clicking an element in the symbol display either opens the sub-
ordinate hierarchy level or a component faceplate. The compo-
nent faceplate offers various views of the associated component
with additional device-specific information, e.g. an identification,
message or maintenance view.
