Siemens 6GK7443-1EX11-0XE0 is a CP 443-1 communication processor for SIMATIC S7-400. It connects the controller to Industrial Ethernet. The communication services include S7 communication and open SEND/RECEIVE connections. ISO transport, ISO-on-TCP, TCP and UDP support the corresponding engineered data paths. The module receives its operating power from the rack backplane.
The 6GK7443-1EX11-0XE0 supports communication in established S7-400 systems. It can link the controller to matching automation equipment and network partners. FETCH/WRITE and time synchronization are available within the supported configuration. Replacement work should verify the CPU compatibility and the existing STEP 7 project. The installed interface and cabling must be checked rather than assuming a modern integrated switch arrangement.
Connects a compatible S7-400 CPU to its configured Industrial Ethernet network.
Transfers engineered application data through supported transport services.
Supports the configured NTP time synchronization arrangement in the automation network.
No. It is a single-interface communication processor, not a multiport switch.
No. This order number does not provide C-PLUG configuration storage.
Compare the exact CPU order number and firmware with the CP compatibility information and existing project.
Web-based diagnostics are not provided on this model; use the supported engineering diagnostics.
Ask Jim for actual-item photographs, the stated condition and available inspection details. The quoted warranty is 12 months under the agreed terms.
Confirmed in-stock goods are dispatched immediately after payment is received. Courier and tracking information are supplied after shipment.
Germany – A Germany customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.
India – An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.
Malaysia – A Malaysia customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
