We constantly receive requests regarding a virus protection on our CNC controllers.
This results from constantly new computer virus warning messages. In the following, please find information about the virus protection on SINUMERIK controllers with PCU50 (Microsoft Windows).

General virus protection notes:

The SINUMERIK 840D sl (PCU50) operator components with installed basic / system / HMI software as well as the related software products on data carriers are subject to severe quality checks. Our development and production departments adopt all necessary measures in order to deliver our products without virus. Our software products are subjected to compatibility checks using typical antivirus products, which are an integral part of product system testing.
The compatibility tests are performed using the topical antivirus product versions with our software.

We recommend that you adopt all necessary virus protection measures when working with the CNC controller. This includes the appropriate handling of data carriers, USB sticks and network connections, taking precautions when loading data and performing software installations and much more.
At the machine level, use virus scanners on PC/PGs from the office or engineering environment.

Virus scanner:

Siemens has tested the virus scanners from Trend Micro Inc, Symantec Corporation and McAfee.

The virus scanner hardware / software combinations tested are listed in the following table:

Proper functioning of the antivirus software and patterns must be ensured by performing the relevant tests on the system-specific configurations. The tests performed by Siemens do not map the exact software environment of the system in question. During our tests, the virus scanners have not been installed at the same time on one test system. We have not checked the inter-compatibility of the stated virus scanners. We recommend that you refrain from operating both scanners simultaneously on one PCU50.

Virus scanners from other companies:
We cannot make a general statement regarding other virus scanners, including the home office products of the two manufacturers stated above: Trend Micro and Symantec Corporation.

For more detailed information, please contact your local Siemens office.
