Notes on the Microsoft updates 2018-01 (Meltdown and Spectre) with SIMATIC ET 200SP Open Controller
On January 3, 2018, Microsoft released updates for its Windows operating systems to close the vulnerabilities which are grouped under the names Meltdown and Spectre.
The installation of the Microsoft updates regarding Meltdown and Spectre has no effect on the operation of the S7-1500 Software Controller (see also product announcement 109755182). These updates can therefore be installed on the ET 200SP Open Controller, however the free space on the CFast card used must be taken into account:
- 8 GB CFast card: Installation of the Microsoft patches is not possible, because the free space on the card is insufficient for this.
- 16 GB and 30 GB CFast cards: Installation of the Microsoft patches is possible depending on the amount of free space.
We therefore recommend switching the memory card to the latest 30 GB type (6ES7648-2BF10-0XK1) before installation.
You can find the latest information on the Microsoft updates 2018-01 regarding Meltdown and Spectre in the product note 109754953.
