Product Details

• Part Number 1 6ES5526-3LA11

Product Description

Within the Simatic S5 product line, Siemens 6ES5526-3LA11 serves as a Communications Processor.

From a maintenance perspective, controller hardware forms a central decision-making element in the system, processing configured logic and exchanging information with I/O, operator, and communication components as supported by the installed platform. The product should be matched to the documented control-system position.

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 installed revision should be confirmed before the product is applied.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Application should remain aligned with the documented system design.
