SIMATIC PCS 7 Maintenance Station 11

Overview of components on a PROFIBUS segment with symbol displays

Symbol displays and component faceplates

The conditions of the compo-

nents or also of subordinate com-

ponents are visualized using

standardized symbol displays in

the diagnostics displays. The

symbol displays of the compo-

nents contain:

• Bitmap of component

• Tag designation of component

• Maintenance state display

• Group display for maintenance messages from subordinate

components

Clicking an element in the symbol display either opens the

subordinate hierarchy level or a component faceplate. This

faceplate contains various views of the respective component

in which further device-specific information can be output.

There are three standard views.

Identification

Depending on the component, the identification view displays

all information available from the hardware configuration or

via SIMATIC PDM in the device description, of the Electronic

Device Description (EDD). In addition, the maintenance status

is displayed and, if available, the status of a redundant compo-

nent.

Messages

The Messages view displays diagnostics error messages, ope-

rator inputs, and maintenance requests.

Maintenance

The Maintenance view is used for the response of the operator

to a maintenance request of a component. Maintenance work

can be requested. The status of the work can also be specified.

This is recorded, and signaled in the symbols. A work instruc-

tion number and a comment can still be entered for each work

request. The instruction number has no effect within the

Maintenance Station and is only included in the report. This

can be used for transfer to maintenance planning.

Process Device Management

There are additional views depending on the diagnostics capa-

bility of a device. For example, in the component operating

display for intelligent field devices (DP, PA, HART), additional

information is output that the Process Device Management

(PDM) makes available. Changes in the parameterization are

managed in a change logbook and can be called up from the

Maintenance Station. In this case, the time and name of the

responsible operator are output.

Configuration changes can also be output. The diagnostic in-

formation of intelligent field devices is determined with the

PDM on the basis of the EDD of a field device. In the EDD, the

device manufacturer also specifies, for example, the supple-

mentary information to be provided in the event of faults. This

can also display the cause, a trend statement and instructions

for clearing the fault. In addition, PDM can be called directly

from the faceplate. This call makes all vendor-specific informa-

tion and documents incorporated by the vendor available for

intelligent field devices.
