Remote Diagnostics Of A Pcs 7 System - Siemens SIMATIC PCS 7 Service Manual

Back up the diagnostic folder
1. Close WinCC.
2. Back up all diagnostic folders of WinCC◆
(default: [Installation path]\Siemens\WinCC\Diagnostics).
3. Give this information to the service employees.
You can back up the diagnostic files using the shortcut menu command Save to >
Compressed (zipped) Folder.
Note
Once the diagnostic files are backed up (not in diagnostic folder), you can delete the content
of the diagnostic folder. In this way, you avoid keeping old information in the new diagnostic
files.
If the same error occurs the next time you start WinCC, make an additional backup to help
the experts. Only a few messages will need to be analyzed in this backup.

Security requirements
If you want to run remote diagnostics in a PCS 7 system, you need to protect this plant against
unauthorized access.
You need to take several measures to implement a security concept. Only the entirety of all
security measures provides optimum protection for a system.
You can find additional information on this in the whitepaper Safety Concept in PCS 7 and
WinCC - Basic Document.

The data can be transmitted along the following routes:
● Telephone line (modem)
● Network connection (e.g. internal TCP/IP connection of the plant)
Options of remote diagnostics and remote administration of a PCS 7 plant

PCS 7 V8.0.
