Product Details

• Part Number 1 6GK7443-5DX03-0XE0

Product Description

6GK7443-5DX03-0XE0 is identified by Siemens as a Communication Module within the Simatic S7 family.

For replacement planning, communication modules move control and status information between system elements, helping controllers, networks, operator resources, or external computers exchange data through the architecture named in the product description. The documented module assignment should remain the basis for selection.

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 assigned system function should be preserved through installation and service.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Ratings and capacity should be verified against the exact model documentation.
