TIA Portal V13 SP1 was not originally built for Windows 10 or Windows 11. While it can sometimes run using compatibility mode, installing it on unsupported modern operating systems frequently causes communication driver failures or installation errors. For modern OS environments, migrating the project to V16, V17, V18, or newer is highly recommended. Hardware Requirements Installation Fixes : Improved reliability when using the
| Area of Improvement | Details from Changelog | | :--- | :--- | | | Additional reasons for the W#16#80C4 (temporary communication error) status were identified for instructions like TCON , TSEND_C , and TRCV_C . One noted cause was firewalls blocking required ports in the communication path. | | D_ACT_DP Instruction | It was clarified that the D_ACT_DP instruction, used for enabling/disabling DP slaves, cannot be used on IE/PB Link PN IO-type gateways. Using it could result in an error code W#16#8093 . | | GET_IM_Data Instruction | A correction was made regarding error code reporting. When reading identification and maintenance data, the displayed error code would be 80C3 instead of 807F , but the same explanation for 807F applies. | | SCL Editor | New keyboard shortcuts were introduced in the SCL block comparison editor to simplify navigation between code changes. | | Optimized Data Blocks | A highly practical improvement was added: the ability to switch a Data Block (DB) between standard and "optimized" block access. |
