Updating firmware on PLCs and HMIs can be a nerve-wracking experience. Update 4 included an updated version of ProSave, the utility used for OS updates and backups. The updated tool improved the reliability of transferring operating systems to SIMATIC HMI panels, reducing the risk of "bricking" a panel during an update—a vital improvement for field engineers.
To appreciate Update 4, you must first understand the initial state of TIA Portal V13. Released as a successor to V12, V13 introduced native support for Windows 8.1 and Windows Server 2012, along with early integration for S7-1200 V4.0 and S7-1500 CPUs. However, early versions of V13 SP0 and even SP1 suffered from three chronic pain points:
