4. Why is diagnostic important?

5. Unrestricted © Siemens AG 2019
Failures in a plant can have many causes:
•Wire break
•Short circuit
•Component failure
•Programming Errors
•Mechanical Impact(ex. accident with forklift truck)
•…
Especially with sporadic errors the search can
be very time-consuming
The primary goal in the event of an error is a fast
localization in order to avoid production downtime.

Use casedescription
Initial Situation
The DigiDemo machine serves as a demonstration platform for
digitization applications. To enable the Siemens regions to
demonstrate the digitization cases to their customers
worldwide, it was decided to produce a new one.
Process
•Mechanic: Build the machine
•Electrician: wire the machine according to the diagram
•Programmer: Project Planning & Development
•Commissioner: Commissioning of the machine
•Operator: Operation of the machine
•Service: Troubleshooting

Use case description
Goal
Each of the previous groups of the development
chain is looking for a way to diagnose errors so they
can quickly identified and corrected them to save
time and effort.
The mechanic has finished the construction of the
machine, so it can be wired.

Use Case: Wiring error.
The electrician has connected all devices of Digidemo machine according
to the topology sent by engineering. The electrician checks with
PRONETA if the wiring is correct.

Cabel test
Diagnostic on LEDs
•Most SIMATIC modules (ex. Decentralized periphery) have
LEDs through which basic diagnostics can be performed.
•Diagnostic via LEDs provides operating information status of
the device about internal/external errors.
•LEDs could help to localize an error.

Use Case: Hardware failure on a ET200SP
Before the electrician starts with the signal wiring, He must check the IO
of all the ET200SP, he suddenly finds
a channel of a ET200SP is not working!
Reason: Hardware Failure...!

Use Case: Programming error
The engineer has finished the program, now he has to test it with
PLCSIM Advanced in order to deliver it to the Commissioning engineer.
The programmer realized that as soon as he download the project,
the PLC changes to STOP and can no longer be set to RUN.
An error message „Cycle time has been exceeded“ is displayed in the
diagnostic buffer in the TIA Portal.
Reason: recursive blocks calls, logic errors...!

Use case: Detect event and generate message
The engineer has used system functions and error OBs in the user
program so that the operator can quickly recognize and correct events.
He has programmed monitoring with Program_Alarm and parameterized
the failures with ProDiag and messages are generated according with the
current faults.

Use Case: Firmware discrepancy
The DigiDemo is mechanically and electrically ready and the programmer
has send the project, so the commissioning engineer on site can start up
the software commissioning, but when is trying to download an error
appears because.
The firmware of the project and the real PLC are different!
Reason: Differences between hardware that has been configured in TIA
Portal and the real one.

Trace
Recording of signals from the current program of the PLC at a
defined interval over a certain period of time.
Recording the signals
•can be started manually or with a trigger condition
•is displayed graphically and can be easily evaluated
•is stored and activated on the device
•can be permanently stored as a measurement in the TIA
Portal.
Completed measurements can be viewed via the PLC
webserver.

How can mistakes be avoid?
Tipps and tricks
DF FA S SUPPage 36
Plant identification system
Avoid time-consuming searches for the failed device by
clearly identifying systems, devices and functions.
X1 Designation of the entire plant
X2 Number of the entire system
Y3 Name of the main component
Y4 Name of the subgroup within the main component
Z5 Number of the device or module according to the device list
zz (6,7) Serial number of the device, the assembly within the subgroup of
the main component
Use a plant identification system for uniform and
systematic identification of machines and plants.
Ex.:= XX.YY - Z.zz

Risk analysis
Avoid system downtime by coupling all devices to a key unit,
since a failure of the unit means a complete failure of the
system.
Perform a risk analysis in advance to calculate the cost
of failure and plan your plant based on the results

Programming Guideline
Avoid typos, clerical errors and program errors
in engineering
Use the programming guide line helps to
•create easily readable and understandable program code
•support program code in the diagnosis of program errors
•To ensure easy maintenance and simplified further development
Use the Style guide Checker to detect errors in time and to optimize
your user program before commissioning!

More Tipps
Avoid message chaos Classify messages by priority and urgency using alarm
classes and groups.
Prevent generate a lot of reports Use ProDiag for generate structured alarm messages
Ensure that the systems synchronize with each other
when using third-party systems.
Use the same timestamp for all systems
