Show PCS 7 Smart Alarm Hiding States in the Process Object View

To expose smart alarm-hiding states 11–32 while engineering, customize the Process Object View (POV) message columns in SIMATIC Manager and enable the required mask column. The accepted solution is Options > Customize > Columns > Process Object View > Messages. This changes which message properties POV displays; it does not create STRep states or itself configure WinCC runtime hiding.

Why states 11–32 are not visible in the current view

The discussion says the STRep block carries a 32-bit mask, but the corresponding fields are not visible in Process Object View (POV). The accepted answer says to customize the POV message columns. This addresses what the engineering view displays; it does not itself create state assignments or change WinCC runtime hiding.

Customize the Process Object View columns

In SIMATIC Manager, open Process Object View and select the Messages category.
Choose Options > Customize > Columns.
In the customization dialog, select Process Object View > Messages and enable the needed mask/message column. Exact labels may vary by PCS 7 version.
Apply the view change and inspect the relevant message rows to see whether the intended alarm-hiding field is now displayed.
Separately verify STRep state assignment and OS alarm logging configuration. Siemens' alarm-hiding example describes the POV message matrix as an input to OS compilation; column visibility alone does not complete runtime configuration.

Distinguish engineering visibility from runtime behavior

The Siemens V10.0 alarm-hiding application example describes OS compilation using the message matrix from Process Object View to generate alarm-hiding attributes and status-tag associations for block groups. That supports checking the configured message matrix and STRep mapping after making the column visible. The source's accepted response only resolved the missing POV column; follow the installed release's documented OS compile/reactivation procedure for changes that affect runtime.

Version and mask considerations

The source does not name the PCS 7/WinCC version or exact unavailable column. Use the menu wording and alarm-hiding documentation for the installed version. A 32-bit carrier does not alone prove every state is correctly assigned or that runtime hiding behaves as intended.

Verification

Confirm the required POV column is visible and inspect relevant messages. Independently check STRep state mapping and WinCC hide-mask configuration, compile the OS as required for the release, then test a representative alarm/state in an approved environment.

Limitations and Operational Precautions

The official supporting example is PCS 7 V10.0, while the source version is unknown. Alarm hiding affects operator alarm presentation. Validate state mapping and message visibility with operations before applying OS changes.

Engineer FAQ

Does column customization configure states 11–32? No. It makes message fields visible; state mapping remains a separate configuration.

What menu path did the accepted answer give? Options > Customize > Columns > Process Object View > Messages in SIMATIC Manager.

Does a visible mask prove runtime hiding works? No. Verify STRep mapping, OS message configuration, compilation and runtime.

What is STRep's role in the cited example? The example associates a status tag of STRep with each configured alarm group.

How does POV affect OS compilation? The V10.0 example says its message matrix is used to generate OS alarm-hiding attributes.

Can menu labels differ? Yes; check the installed PCS 7 release and available message columns.

Does a 32-bit mask prove all states are configured? No. Verify each state and its mapped alarm group.

What should be tested in Runtime? A representative alarm assigned to the state/group being validated.

Which version does the Siemens example cover? PCS 7 V10.0, application example V6.0 (2025).

What operational review is needed? Confirm alarm presentation with operations because hiding changes what operators see.
