The maintenance engineer can process the diagnostics mes-

sages and maintenance requests of the assets on the mainte-

nance station. Via the maintenance station the engineer can ac-

cess:
• Components of the process control system, e.g. intelligent 

field devices and I/O modules, fieldbus, controller, network 

components and plant bus as well as servers and clients of 

the operator systems

• Assets that do not belong directly to the process control sys-

tem, such as pumps, motors, centrifuges, heat exchangers or 

control loops (passive or indirect assets). These are repre-

sented by proxy objects in which the diagnostics rules are 

stored.

The maintenance station for PCS 7 asset management uses 

hardware and software components of the engineering system 

and operator system. As a result of the close interlacing, ES, OS 

and asset management functions execute on common hard-

ware. Such a multi-functional station cannot only be used for as-

set management, but also for system engineering or HMI. 
The message system, user desktop, display hierarchy and oper-

ator prompting are oriented according to the HMI philosophy of 

the operator system. The diagnostics data of all assets are dis-

played on uniform faceplates whose contents depend on the in-

telligence of the respective component. This means that working 

with the maintenance station is simple and intuitive – complex fa-

miliarization is not required.
The diagnostics displays structured according to the plant hier-

archy with the operating states of all PCS 7 components can be 

displayed on the maintenance station and also on an OS client. 

However, enhanced online diagnostics functions in conjunction 

with HW-Config or SIMATIC PDM can only be called from the 

maintenance station. 
The user management and access control for the maintenance 

station accept the SIMATIC Logon integrated in SIMATIC PCS 7. 

■

Depending on the architecture of the SIMATIC PCS 7 plant, the 

maintenance station can be implemented based on a SIMATIC 

PCS 7 BOX RTX/416, PCS 7 single station or client/server com-

bination.
The following table shows possible hardware/software configu-

rations of the maintenance station (MS).

Two MS servers can also be operated as a redundant pair of 

servers. The redundant MS servers must be configured like re-

dundant OS servers and expanded by the SIMATIC PCS 7 Asset 

Runtime software.
The SIMATIC PCS 7 Asset Runtime basic package already con-

tains 100 asset TAGs. These can be expanded by cumulative 

SIMATIC PCS 7 Asset Runtime licenses for 10, 100 or 

1000 asset TAGs (Count Relevant Licenses).
