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).

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.
