Extend an S7-400 station to a controlled PROFIBUS segment

CP 443-5 Extended connects a SIMATIC S7-400 or S7-400H station to PROFIBUS DP. It also supports S5-compatible, PG/OP and S7 communication services.

Before you order: Check the installed CPU, CP hardware and firmware, STEP 7 project, bus address and DP network before choosing a replacement.

Description

The CP 443-5 Extended is a communications processor, not a standalone controller. In an S7-400 installation it provides a separate PROFIBUS interface for DP and other communication services while the CPU and STEP 7 project define the application.

During a controlled exchange, archive the hardware configuration and communication blocks, record the bus parameters and connected stations, and compare the current firmware with the approved project. Siemens warns against loading changed bus parameters to the CP over the very PROFIBUS link being changed.

Communication & Connectivity

The official data sheet lists one PROFIBUS electrical interface, a 9.6 kbit/s to 12 Mbit/s transfer-rate range and DPV1 master capability. Verify the actual network topology and termination.

Configuration & Programming

The Siemens manual lists STEP 7 V5.5 SP1 or STEP 7 Professional V12 for the documented full function set. Compare the installed firmware and CP catalog entry before loading.

Upgrade Recommendations

A later CP or firmware is not automatically a drop-in spare. Verify S7-400 CPU support, configured communication services and the machine owner's approved project.

FAQ

How can I check whether 6GK7443-5DX05-0XE0 will work in my S7-400 rack?

Compare the exact order number and hardware release with the CPU, rack and STEP 7 hardware configuration. Confirm the PROFIBUS role and current firmware before ordering.

What should I back up before replacing 6GK7443-5DX05-0XE0?

Save the approved STEP 7 project, CP configuration and communication blocks. Record PROFIBUS address, baud rate, DP slave list, termination and current diagnostic buffer.

Why do DP slaves remain offline after 6GK7443-5DX05-0XE0 is installed?

Check bus power, connectors and termination first, then compare master address, baud rate, slave addresses and downloaded configuration. Read CP and slave diagnostics before changing hardware again.

Can I change the PROFIBUS baud rate through 6GK7443-5DX05-0XE0 while connected over that same bus?

Do not rely on that route. Siemens warns against loading changed bus parameters through PROFIBUS; use a suitable alternative engineering connection and a controlled change window.

What if 6GK7443-5DX05-0XE0 powers up but PG/OP communication fails?

Confirm the PG/OP service is configured, the target address and bus parameters match, and the required STEP 7 project and block versions are loaded. Separate a network fault from a CP configuration mismatch.

What should a buyer send when requesting 6GK7443-5DX05-0XE0?

Provide a nameplate photo, full order number, hardware and firmware versions, S7-400 CPU model, configured CP role and any site requirement for a like-for-like service spare.
