IEC 60617 CAD Symbol Library Needed if you have

if you have ready then only, I need a complete IEC 60617 control & instrumentation symbol library in both DWG and DXF formats for direct use in AutoCAD and other CAD tools.

Scope:
Accurate IEC-standard symbols (clean, 1:1 scale, proper layers)
Include outlines for Siemens SIMATIC S7-1200 modules for PLC-SCADA layouts

Deliverables:
Full symbol library (DWG + DXF) with organized folders
Separate files/layers for S7-1200 hardware outlines
Short read-me (naming + scaling standards)

Requirements:
Clean linework (no errors)
Correct layers & scale
Ready to insert into existing drawings

I will review a sample first; once approved, full delivery can proceed.
