Product Details

  • Part Number 1 6ES7791-2BA20-0AA0

Product Description

For Simatic S7 system applications, Siemens 6ES7791-2BA20-0AA0 provides the function of a Hard Drive Kit.

Memory and storage components retain program, configuration, or operating information used by compatible automation hardware. Capacity, data type, and retention behavior depend on the exact module design. Its role should remain distinct from that of similarly named assemblies.

Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. The original equipment schedule should guide compatibility review.

When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. Ratings and capacity should be verified against the exact model documentation.
