More Information

Overview Manuals PROFIBUS DP Connection Resources Rack Integration Engineering

Features:

  • One RS-485 PROFIBUS interface provides DPV1 master, S5-compatible, PG/OP and S7 communication services.
  • Open SEND/RECEIVE traffic and S7 communication use separately specified connection resources.
  • The compact single-width processor receives operating power from the S7-400 backplane.
The 9-pin Sub-D connector forms the fieldbus boundary between the central rack and the configured PROFIBUS stations.

DP input data is mapped into the master address area, while output data returns through the assigned slave relationships.

STEP 7 defines bus settings, connection resources and the communication blocks used by the controller program.

The Siemens 6GK7443-5DX05-0XE0 SIMATIC NET CP 443-5 Extended Communication Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6GK7443-5DX05-0XE0 SIMATIC NET 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.

From the master connector to slave data

  • Physical interface: One 9-pin Sub-D RS-485 socket connects the CP to the PROFIBUS segment.
  • Master role: DPV1 services coordinate cyclic data and supported acyclic exchanges with configured slaves.
  • Address areas: The master maps separate total input and output areas, with a defined per-slave data limit.
  • Bus rate: The project selects a PROFIBUS rate within the supported 9.6 kbit/s to 12 Mbit/s range.

Allocating communication services

  • SEND/RECEIVE: Open communication uses its specified pool of connections and user-data length per connection.
  • S7 communication: S7 services draw from a separately stated maximum connection count.
  • DP influence: The maximum active multi-protocol connections changes when the DP master function is operating.
  • Station total: CP quantity and master roles must be checked together with other communication processors in the S7-400 rack.

Power and slot relationship

  • Module format: The processor occupies one compact S7-400 module width in the central rack.
  • Backplane power: The rack supplies 5 V DC through the backplane, so no external module-supply connector is used.
  • Thermal boundary: The documented power loss and operating-temperature range apply to the installed rack arrangement.
  • Protection: IP20 construction requires the surrounding equipment to provide the necessary enclosure.

Turning station requirements into a CP project

  • Supported tools: Configuration uses the documented STEP 7 or STEP 7 Professional release.
  • Bus parameters: The project assigns the PROFIBUS address, rate and DP master relationships.
  • Program interface: SEND/RECEIVE blocks and S7 connections must stay within the CP resource limits.
  • Commissioning check: Actual slave addresses and segment wiring must match the downloaded hardware configuration.
Description
Siemens 6GK7443-5DX05-0XE0 is the SIMATIC NET CP 443-5 Extended communication processor for S7-400. It adds the PROFIBUS DP master path and the S5-compatible, PG/OP and S7 communication services used by the configured station.

Fieldbus traffic enters 6GK7443-5DX05-0XE0 through one 9-pin RS-485 connector. As a DPV1 master, the processor exchanges the assigned input and output address areas with as many as 125 configured DP slaves at the selected PROFIBUS rate.

Open communication on 6GK7443-5DX05-0XE0 uses SEND/RECEIVE blocks, while S7 communication maintains a separate connection resource pool. Multi-protocol limits therefore depend on whether the CP is also operating its DP master segment.

Rack power for 6GK7443-5DX05-0XE0 arrives through the 5 V S7-400 backplane rather than an external supply connector. The station project assigns its bus parameters and connection resources using the supported STEP 7 engineering release.

Technical notes
Siemens 6GK7443-5DX05-0XE0 provides one RS-485 PROFIBUS interface for DPV1 master, S5-compatible, PG/OP and S7 communication in an S7-400 rack.

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 can the available connection count of 6GK7443-5DX05-0XE0 change when PROFIBUS DP is enabled?
The 6GK7443-5DX05-0XE0 shares processor resources across DP, open and S7 communication, so the documented multi-protocol maximum is lower with the DP master active.
Which connector should be used for the PROFIBUS segment on 6GK7443-5DX05-0XE0?
The 6GK7443-5DX05-0XE0 provides one 9-pin Sub-D RS-485 socket for its PROFIBUS connection.
What must agree before 6GK7443-5DX05-0XE0 can exchange data with a DP slave?
The 6GK7443-5DX05-0XE0 project and the physical network must agree on the slave address, baud rate, bus wiring and assigned input/output data areas.
Does 6GK7443-5DX05-0XE0 need a separate external power supply connector?
No. The 6GK7443-5DX05-0XE0 receives its 5 V DC operating supply from the S7-400 backplane.
How should SEND/RECEIVE data size be planned on 6GK7443-5DX05-0XE0?
Each open-communication connection on 6GK7443-5DX05-0XE0 must remain within the documented 240-byte maximum user-data length and the overall connection limit.
