Is the 6GK7443-1EX30-0XE1 compatible with TIA Portal?

The CP 443-1 EX30 is primarily configured via SIMATIC STEP 7 V5.x and SIMATIC NCM PC. Limited TIA Portal support may be available via legacy device libraries. For new projects, SIEMENS recommends the CP 443-1 EX40 (6GK7443-1EX40-0XE0) which has full TIA Portal integration.

Can this module act as both PROFINET IO Controller and IO Device simultaneously?

Yes. The 6GK7443-1EX30-0XE1 supports simultaneous PROFINET IO Controller (up to 128 IO devices) and PROFINET IO Device operation, making it suitable for hierarchical and multi-controller network architectures.

What is the difference between 6GK7443-1EX30-0XE1 and 6GK7443-1EX11-0XE0?

The EX30 (Advanced) supports PROFINET IO Controller/Device, MRP ring redundancy, dual-port switch, and advanced IT functions. The EX11 is an earlier, more basic variant with fewer simultaneous connections and no integrated switch. The EX30 is the recommended choice for new installations.

Do you supply new, refurbished, or surplus units?

Konmask.com supplies both new (factory-sealed) and tested surplus units depending on availability. All units are clearly identified by condition in the quotation. We do not supply untested or unverified components.

What is the typical lead time for the 6GK7443-1EX30-0XE1?

Lead time varies by stock availability. In-stock units typically ship within 2–5 business days internationally. For out-of-stock items, sourcing lead time is typically 1–3 weeks. Contact us for real-time availability.

Is export documentation provided?

Yes. Full export documentation is provided with every international shipment, including commercial invoice, packing list, and certificate of origin upon request.

Description

SIEMENS 6GK7443-1EX30-0XE1 CP 443-1 Advanced Ethernet Communication Processor – SIMATIC NET S7-400 Series

When an S7-400 PLC loses its Ethernet communication backbone, the consequences cascade instantly: SCADA systems go blind, MES data pipelines stall, and plant operators are left managing critical processes without real-time visibility. In high-throughput manufacturing, pharmaceutical batch control, or power distribution substations, even minutes of communication downtime translate into production losses and safety risks. The SIEMENS 6GK7443-1EX30-0XE1 CP 443-1 Advanced is the communication processor engineered to prevent exactly this scenario — delivering deterministic, high-speed Industrial Ethernet connectivity that keeps your S7-400 system fully integrated with the plant network.

Within the SIMATIC NET CP 443-1 family, the 6GK7443-1EX30-0XE1 represents the Advanced tier — the highest-performance variant designed for demanding multi-protocol environments. Supporting PROFINET IO Controller/Device, ISO-on-TCP, TCP/IP, UDP, and S7 communication simultaneously, it is the preferred choice for system integrators building large-scale distributed control architectures. Globally, this module is deployed across automotive assembly lines, chemical process plants, energy management systems, and intelligent building automation — wherever the S7-400 platform demands enterprise-grade network integration.
