WinCC/ProAgent
Increased availability through process diagnostics
Increased productivity is being achieved more and more by
cutting costs. In this context, the focus is increasingly on
maintenance. The emphasis here is on rectifying faults as
quickly and efficiently as possible. Ideally, the operating personnel
should also perform part of the maintenance tasks.
The operating personnel are on-site, they are familiar with the
procedures and can intervene quickly. This saves time and reduces
costs. It is precisely here that ProAgent can assist operating
personnel in identifying faults quickly, particularly in the
automotive and machine tool industries.
Benefits
- Component of Totally Integrated Automation:
Increases productivity, minimizes engineering outlay,
reduces lifecycle costs
- Support for troubleshooting, increased machine and
plant availability, shorter downtimes
- No additional configuration costs for the diagnostics
functionality due to automatic generation of the diagnostics-
related parts for the controller and HMI
- Frees up controller capacity with regard to memory
requirements and program execution time
- No special knowledge required to operate

In the event of a process fault, process error diagnostics with
SIMATIC ProAgent will provide information about the location
and cause of that fault and support personnel with troubleshooting.
The ProAgent solution has been optimized specifically
for use with SIMATIC S7-300/S7-400 and SIMATIC WinAC. It
can be used in combination with the S7-PDIAG, S7-GRAPH
STEP 7 engineering tools. The ProAgent option package features
standard displays that are updated with process-specific
data during runtime.

Standard views instead of configuration
ProAgent is available for various devices and software platforms
from the SIMATIC HMI range: Panels and Multi Panels,
WinCC flexible and WinCC. ProAgent contains standard views,
which are attuned to the requirements of the process error diagnosis
of a plant or machine. During configuration, the data
that is relevant to process error diagnostics such as symbols,
comments and alarm texts are saved in a standardized data
management system. During runtime, the standard screens
are then filled with process-specific data.
For SIMATIC WinCC, ProAgent directly accesses the engineering
data and imports it into the WinCC project. The ProAgent
standard screens needed for the diagnostics mode are automatically
created in WinCC. ProAgent and STEP 7 engineering tools represent a standardized diagnostics concept for
SIMATIC S7. No additional configuration overhead for the
WinCC application is thus required for the diagnostics
functionality. The standard views are: alarm view, unit overview, diagnostics
detailed view, motion view and the sequencer operating display.
Functional scope
- Context-sensitive diagnostics initiation due to process error
message
- Output of the operands with symbols and comment
Switch-over capability between LAD, STL and signal list
- Supporting fault rectification by means of direct process access
when using the motion view
- Output of the faulty operands directly in the alarm including
address, symbol and comment
- Consistency test in runtime: Inconsistent diagnostics units
are marked with icons. This permits quick locating of faults
regarding configured data in the commissioning phase.
- Direct, unit-related entry point in the diagnostics view from
user displays (by using ProAgent functions)
- Unit or alarm-related entry to STEP 7, e.g. LAD/STL/FBD editor,
S7-GRAPH, HW CONFIG upon system error messages, is
supported fully automatically
- S7-GRAPH OCX for the graphical display of step sequences
