Siemens | Simatic S5 6ES5256-3AB21

Product Details

• Part Number 1 6ES5256-3AB21

Product Description

6ES5256-3AB21 is identified by Siemens as a VISRAM 256 Video Module within the Simatic S5 family.

For replacement planning, this component performs the specialized system function identified by its product designation within the associated automation platform. Its exact capabilities are determined by the installed configuration and product revision. The documented module assignment should remain the basis for selection.

In a SIMATIC S5 system, module selection is governed by the controller family, rack arrangement, electrical interface, and configured program. The exact article number should be matched before installation. The product remains part of the broader control and signal-handling arrangement.

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. This helps preserve the function assigned to the installed control node.
