More Information

Overview Manuals DPV1 Device Map Communication Services Backplane Exchange Project Configuration

Features:

  • One RS485 interface connects the S7-400 rack to PROFIBUS at up to 12 Mbit/s.
  • DPV1, S5-compatible, PG/OP and S7 communication use separate processor resources.
  • The backplane supplies power and exchanges data with the S7-400 CPU.
Controller data reaches the CP over the S7-400 backplane.

The selected communication service maps that data into PROFIBUS frames for the connected station.

Responses and diagnostic states return through the same CP while STEP 7 keeps hardware and program resources aligned.

The Siemens 6GK7443-5DX03-0XE0 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).

Coordinating cyclic data for as many as 125 PROFIBUS slaves

  • Slave count: The DPV1 master addresses up to 125 devices.
  • Total input map: All slaves share a 4096-byte input area.
  • Total output map: All slaves share a 4096-byte output area.
  • Per-device boundary: Each slave remains within 244 input bytes and 244 output bytes.

Sharing one processor across different PROFIBUS message paths

  • SEND/RECEIVE: Sixteen open-communication connections are available.
  • User data: Each SEND/RECEIVE connection carries up to 240 bytes.
  • S7 communication: A separate pool permits up to 48 connections.
  • Programming access: PG/OP traffic uses the same physical PROFIBUS interface.

Moving controller data between the CPU and communication processor

  • Rack supply: The S7-400 backplane provides 5 V DC.
  • Typical current: The module draws 1.3 A from the backplane.
  • Processor loss: Documented power loss is 6.5 W.
  • Rack capacity: A CPU can use up to 14 documented communication processors.

Aligning the rack slot, PROFIBUS map and programmed connections

  • STEP 7: Version 5.4 SP4 or higher configures the hardware.
  • NCM S7: PROFIBUS engineering defines network and communication parameters.
  • DP mapping: Slave addresses and data lengths must fit total and per-device limits.
  • Block calls: Programmed SEND/RECEIVE or S7 services must match the configured connection resources.

Description
Siemens 6GK7443-5DX03-0XE0 is a CP 443-5 Extended communication processor for the SIMATIC S7-400 system. It links the controller rack to one PROFIBUS network and carries DPV1 master, S5-compatible, PG/OP and S7 communication through its RS485 interface.

At bus rates from 9.6 kbit/s to 12 Mbit/s, 6GK7443-5DX03-0XE0 can coordinate as many as 125 DP slaves. The processor separates total DP input and output areas from the smaller per-slave limits, so the station configuration must satisfy both levels of the data map.

Open communication on 6GK7443-5DX03-0XE0 provides up to sixteen SEND/RECEIVE connections with a documented user-data limit for each connection, while S7 communication uses a separate pool of up to forty-eight connections. These services share the same processor and PROFIBUS interface but retain different connection resources.

The S7-400 backplane supplies 6GK7443-5DX03-0XE0 with 5 V DC and carries data between the CP and CPU. STEP 7 together with NCM S7 for PROFIBUS defines the hardware slot, bus parameters, DP slaves and programmed communication connections.

Technical notes
The single RS485 path on Siemens 6GK7443-5DX03-0XE0 shares processor resources across DPV1, S5-compatible, PG/OP and S7 communication services.
