STEP 7 (TIA Portal): Tia18 Running out From resources

Hello everyone.
After opening one of the projects from TIA15.1 on TIA18 and all projects stopped opening for me on TIA 18. My main problem is this:
"The integrity monitoring service is running out of resource.
Release resource by closing applications currently not in use."
Has anyone had similar problems know how to fix it?

Regarding "Integrity Monitoring Service" Resource Issue in TIA Portal V18

Hello,

You're experiencing a known issue where the Integrity Monitoring Service in TIA Portal V18 can run out of resources, especially after opening older projects (like from TIA Portal V15.1). This often manifests as projects failing to open and the error message you received.

Here are some troubleshooting steps:

  • Close Unnecessary Applications: As the error suggests, close all other applications, including web browsers, Office programs, and any other software consuming system resources.
  • Restart TIA Portal: A simple restart can sometimes resolve temporary resource conflicts.
  • Increase Virtual Memory: Increase the virtual memory (paging file) size on your system. See Siemens FAQ for details on adjusting virtual memory.
  • Check System Resources: Ensure your computer meets the minimum hardware requirements for TIA Portal V18.
  • Project Conversion: Converting the project within TIA Portal V18 might help resolve compatibility issues.

If the problem persists, consider checking the SiePortal for known issues and solutions specific to your hardware/software configuration: SiePortal. You may also need to consider updating your TIA Portal to the latest update/patch version.

Sincerely,
Siemens Self Support
