More Information

Overview Manuals DP Data Map Connection Budget Rack Interface Engineering Match

Features:

  • The CP 443-5 Extended places an isolated PROFIBUS DPV1 master in the S7-400 rack.
  • DP device data is mapped into separate input and output address areas for the station CPU.
  • Conformal coating distinguishes the complete -0XE1 order configuration.
The processor links the S7-400 backplane to one RS485 PROFIBUS network.

Connection limits divide communication resources between the complete processor and each participating CPU.

Engineering software assigns addresses, bus parameters and services before the rack begins cyclic operation.

The Siemens 6GK7443-5DX05-0XE1 CP 443-5 Extended Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6GK7443-5DX05-0XE1 CP 443-5 Extended Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Relating each device to the processor address space

  • Master role: The communication processor coordinates the configured DPV1 devices.
  • Input image: Device input bytes are collected inside the processor's total input address area.
  • Output image: CPU output data is assigned to the corresponding DP device addresses.
  • Device boundary: Each slave remains within the documented per-device input and output limits.

Allocating S7 communication resources

  • Total pool: The processor can maintain the documented overall number of S7 connections.
  • CPU share: A single CPU can use only its stated portion of that total resource.
  • Service mix: PG/OP, S7 and S5-compatible communication occupy distinct configured services.
  • Planning check: Connection demand is reviewed before the station is loaded.

Linking backplane power to field communication

  • Rack supply: The processor receives 5 V DC through the S7-400 backplane.
  • CPU exchange: Process data and communication jobs pass through the rack interface.
  • Field connector: The isolated nine-pin Sub-D exposes the RS485 PROFIBUS segment.
  • Enclosure: IP20 hardware remains inside a suitable control cabinet.

Preserving order suffix and project compatibility

  • Software baseline: Configuration uses the documented STEP 7 or TIA Portal release level.
  • Bus settings: Device addresses and transfer rate are defined in the station project.
  • Coated version: The -0XE1 suffix identifies the conformally coated order configuration.
  • Replacement check: Hardware order number and project module selection must agree before download.
Description
Siemens 6GK7443-5DX05-0XE1 is a conformally coated CP 443-5 Extended communication processor that gives a SIMATIC S7-400 station a PROFIBUS DPV1 master interface together with S7, PG/OP and S5-compatible communication services.

Through its isolated nine-pin RS485 connector, 6GK7443-5DX05-0XE1 coordinates PROFIBUS devices at the configured transfer rate. The processor maps each device's input and output data into the address areas exchanged with the S7-400 CPU.

Communication resources inside 6GK7443-5DX05-0XE1 are shared across S7 connections and the attached CPUs. The total connection count and the per-CPU limit therefore describe different allocation boundaries.

Mounted in the S7-400 rack, 6GK7443-5DX05-0XE1 receives 5 V DC from the backplane rather than from a separate field supply. STEP 7 or TIA Portal defines the network, device addresses and communication services that the processor executes.

Technical notes
Installed in the S7-400 rack, Siemens 6GK7443-5DX05-0XE1 draws 5 V from the backplane and exposes an isolated RS485 PROFIBUS interface; preserve the coated -0XE1 order suffix.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why must the -0XE1 suffix be retained when ordering 6GK7443-5DX05-0XE1?
The complete 6GK7443-5DX05-0XE1 order code identifies the conformally coated CP 443-5 Extended configuration. A similar suffix can represent a different environmental construction.
How many PROFIBUS devices can Siemens 6GK7443-5DX05-0XE1 coordinate?
Siemens 6GK7443-5DX05-0XE1 supports up to 125 documented DP devices, subject to the configured address areas, per-device byte limits and available communication resources.
Where does 6GK7443-5DX05-0XE1 receive its operating power?
The 6GK7443-5DX05-0XE1 processor draws 5 V DC from the S7-400 backplane. Do not look for a separate 24 V field-supply terminal on this rack communication module.
A DP device exchanges no data with 6GK7443-5DX05-0XE1; what should be compared?
Compare its PROFIBUS address, transfer rate and input/output mapping with the project loaded for 6GK7443-5DX05-0XE1, then inspect the isolated RS485 connector and bus termination.
Are the 48 S7 connections of 6GK7443-5DX05-0XE1 available to one CPU?
No. The overall resource of 6GK7443-5DX05-0XE1 is up to 48 S7 connections, while the documented limit per CPU is up to 14. Allocate the project accordingly.
Which engineering baseline is needed for 6GK7443-5DX05-0XE1?
Configure 6GK7443-5DX05-0XE1 with the documented STEP 7 V5.4 SP4 baseline or TIA Portal V12 and later, while also matching the installed hardware catalog entry.
