I am cleaning up messages and warnings. Warning : Firmware version : (online) V4.0 <-> (offline) V3.0 I am having trouble selecting the newer firmware version within my TIA v18 compiler. Offline, when i click change version, it doesnt even show my CPU : 6es7 516-3fp03-0ab0, but it is within my hardware catalog. Only online reference i cann find is to upgrade the firmware, but isnt this for the actual hardware rather than the offline project? Firmware update for CPU 1516-3 PN/DP - ID: 78066881 - Industry Support Siemens Attachment Screenshot 2025-12-05 144646.png (7 Downloads)

In TIA V18, S7-1500 firmware can only be configured up to V3.0. Best regards

That doesn't need any actions, it's just a notification. You can check from the cpu's datasheet, how to configure the cpu in a TIA version that doesn't have the support for fw v4.x.
