While V13 SP1 Update 4 is incredibly stable, the underlying hardware components will eventually face obsolescence. Use the built-in migration tools to test how easily your V13 projects can convert to V16 or V19 for future-proofing.
Siemens designed Update 4 to resolve functional bugs and optimize system performance without altering the core project structure.
Totally Integrated Automation (TIA) Portal v13 Service Pack 1 (SP1) Update 4 is a critical maintenance release by Siemens. It enhances engineering efficiency for SIMATIC S7-1200, S7-1500, S7-300, and S7-400 controllers. This specific update addresses system stability, fixes critical bugs, and optimizes performance across the STEP 7 and WinCC environments.
If you are currently troubleshooting a specific issue in your engineering environment, let me know: What or fault symptom are you experiencing?
| 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. |
The topology view accurately reflects real-world cabling during online diagnostics, eliminating ghost device errors.
: F-blocks previously marked as "Unsupported Blocks" are automatically supported after upgrading a project to V13 SP1 Update 4. Multi-instance Tags
If you are running production code on these firmware revisions, Update 4 is not optional—it is mandatory.
