Resolving HW Config Error 1230:2016 - 'No Changes Can Be Made in This Station' in SIMATIC PCS 7

In SIMATIC PCS 7, the error 'HW Config (1230:2016) No changes can be made in this station' indicates that STEP 7 has locked the hardware configuration in read-only mode. This lock occurs when the project contains hardware modules or communication processors requiring software option packages (such as S7 F Systems, SIMATIC Safety, CP 443-1 Advanced profiles, or SIMATIC PDM) or Hardware Support Packages (HSPs) that are not installed on the current Engineering Station (ES). To resolve this, check 'Options -> Specify Software Packages' in SIMATIC Manager to identify missing packages, install the required software and HSPs, and reopen HW Config.

Root Causes of HW Config Lock Error 1230:2016

When an engineer opens HW Config to modify racks, I/O modules, or network parameters, STEP 7 validates the hardware catalog against the software packages and firmware profiles installed on the local PC.

If any discrepancy exists, STEP 7 prevents unauthorized data corruption by locking the station with Error 1230:2016:
1. Missing Software Option Packages: The station contains fail-safe modules (S7 F Systems / F-Configuration Pack), communication processors requiring SIMATIC NET extended profiles, or field instruments managed by SIMATIC PDM. If these packages are absent, HW Config locks.
2. Missing Hardware Support Packages (HSPs): The project contains newer module revisions (e.g. newer ET 200M interface modules or analog cards) installed via HSP on the original authoring PC but missing from the current workstation.
3. Multi-User Editing Locks: If another engineer has opened the station across a network share without multi-project coordination, or if a crashed session left a .ldb lock file in the project database.

Identifying Missing Software Packages and HSPs

To determine the exact missing component without guessing:
* In SIMATIC Manager, select the top-level Project or Multiproject folder.
* Navigate to the menu: Options -> Specify Software Packages... (or Help -> About -> Display...).
* In the dialog, select the tab Required Software Packages.
* STEP 7 displays a side-by-side list comparing software packages required by the project against packages currently installed on the workstation. Any package flagged with a red cross or marked 'Not installed' is the direct cause of error 1230:2016!

Remediation Procedure - Installing HSPs and Clearing Station Locks

Follow this procedure to unlock HW Config:

[Phase 1: Identify Missing Components]
   │  • In SIMATIC Manager: Options -> Specify Software Packages...
   │  • Note missing items (e.g. "F-Configuration Pack", "HSP 0256", "SIMATIC PDM")
   │
[Phase 2: Install Hardware Updates (HSPs)]
   │  • In HW Config: Select "Options -> Install Hardware Updates..."
   │  • Select "Download from the Internet" (or "Copy from disk" if offline)
   │  • Select the required HSPs from the list -> Click "Download" -> Click "Install"
   │  • Close HW Config and re-open to refresh the catalog
   │
[Phase 3: Install Required Option Packages]
   │  • Install missing Siemens software (e.g. S7 F Systems V6.2, PDM V9.0)
   │  • Transfer required licenses via Automation License Manager (ALM)
   │  • Reboot the Engineering Station
   │
[Phase 4: Clear Lingering Project File Locks (If Packages Match)]
   │  • If all packages are installed but lock persists:
   │  • Close SIMATIC Manager
   │  • Open project directory in Windows Explorer -> Search for *.ldb or lock files
   │  • Execute "Save As..." with "With Reorganization (Slow)" to rebuild pointers

Verification

To confirm that HW Config error 1230:2016 is resolved:
1. In SIMATIC Manager, navigate to the AS station and double-click Hardware.
2. Confirm that HW Config opens without the warning dialog 1230:2016 No changes can be made in this station.
3. Verify that the window title bar displays HW Config - [Station Name] without (Read Only) appended.
4. Insert a test module or edit a parameter, then select Station -> Save and Compile; verify that compilation completes successfully.

Limitations and Operational Precautions

Never delete internal STEP 7 database files manually using Windows Explorer unless executing an authorized database repair procedure. Forcing a station to open by deleting hardware database entries can corrupt module driver generation in CFC. Always install the exact option package version that matches the original engineering baseline.

Engineer FAQ

Why does error 1230:2016 occur after opening a client project archive?

The original authoring engineer had additional software packages (such as S7 F Systems, PDM, or specific HSPs) installed on their workstation that are missing from your computer.

Where can I download Hardware Support Packages (HSPs)?

HSPs can be downloaded directly inside HW Config via Options -> Install Hardware Updates -> Download from Internet, or downloaded as an offline archive from SIOS Entry ID 23183356.

Can I bypass the read-only lock without installing the software?

No. STEP 7 intentionally enforces read-only mode to prevent saving a project that the local software cannot fully validate, protecting against CPU memory corruption.

Does 'Save As with Reorganization' fix error 1230:2016?

Only if the lock was caused by an orphaned lock file or minor database index fault. If a software package is missing, reorganization will not remove the lock.
