Tia Portal V13 Sp1 Update 4 ~repack~ | SECURE |

A particularly widespread issue for users of V13 SP1 is that the version only supports firmware up to V4.1 for S7-1200 controllers. A user encountering a CPU with firmware V4.2, but unable to upgrade past V13 SP1, found that TIA Portal would crash when attempting to upload the configuration.

| 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. | Tia Portal V13 Sp1 Update 4
