Can PCS 7 V9.1 Restore Classic CFC F1 Help Instead of PUD Manager
A verified setting to restore classic context-sensitive CFC F1 help in PCS 7 V9.1 has not been established. Siemens documents individual PDF manuals as an alternative reading route in the opened V9.1 SP2 overview. Use a manual matched to the actual block-library version when reading outside PUD Manager, but do not present that alternative as a confirmed restoration of the old F1 behavior.

What Is Established About the Help Route
The reported change concerns pressing F1 with a CFC block selected in PCS 7 V9.1. Replies stated that classic help could not be restored, but no manufacturer setting or version-specific proof was supplied.
Siemens' opened V9.1 SP2 documentation overview describes PUD delivery alongside individual PDF manuals. It does not establish a switch that rebinds block F1 to the old viewer. The precise base-V9.1 F1 restoration question therefore remains unresolved. Documentation overview, Access options.
Read Version-Matched PDFs as an Alternative
This is a documented alternative for manual reading, not a replacement for CFC's context-sensitive F1 binding:
- Record the installed PCS 7, CFC and block-library versions.
- Identify the manual for the selected block's actual library and release.
- Obtain that edition's individual PDF from Siemens' documentation offering. The opened SP2 overview identifies individual PDFs in the support portal and selected manuals under _Manuals on installation media.
- Confirm the PDF's title, edition and applicable version before using it.
- Locate the block's exact identifier and review its description, operating modes and I/O definitions together.
PCS 7 Documentation V9.1 SP2, Access options. This avoids assuming that a similarly named block in an older manual has the same interface.
Distinguish the Other Help Entry Points
The SP2 overview documents SIMATIC Manager > Help > Introduction for PUD documentation and Help > Contents for STEP 7 online help. These entry points are distinct from the selected CFC block's F1 behavior. Documentation overview.
If the requirement is specifically faster block lookup, keep a version-indexed local manual collection as a practical reading arrangement. If the requirement is restoring the old context-sensitive viewer, record the exact F1 route and installed components for a targeted product inquiry. Do not change viewer associations or remove documentation components on an unverified assumption.
Verification
For the PDF alternative, verify that the selected block exists in the chosen edition and that its documented I/O names match the installed definition. Confirm you can retrieve the needed operation and parameter information independently of the F1 viewer.
For any proposed F1 change, test it on a separate representative environment and confirm both context selection and version correctness. No setting change or help-viewer test has been performed.
Limitations and Operational Precautions
The manufacturer reference opened here is V9.1 SP2, while the reported installation was identified only as V9.1. It documents alternate access, not a verified base-V9.1 classic-viewer restoration procedure. The source's absolute "no other way" claim remains unestablished.
Preserve the working documentation installation. Do not copy old help components, edit associations or uninstall PUD Manager as a proposed fix without applicable documentation. A convenient viewer is useful only if its content matches the installed block.
Engineer FAQ
Can this article supply a verified classic-F1 switch? No; that setting was not established.
Can manuals be read without using PUD? The cited SP2 overview documents individual PDFs.
Is STEP 7 Help > Contents the same as block F1? They are distinct entry points; do not equate them.
