Product Description for Siemens 6GK7443‑5DX05‑0XE0 (CP443‑5 Extended Communication Processor Module)
1. Product Overview
6GK7443‑5DX05‑0XE0 is an original Siemens CP443‑5 Extended PROFIBUS‑DP communication processor dedicated for SIMATIC S7‑400 PLC systems. It is plugged into the back‑plane rack of S7‑400 controllers and undertakes all PROFIBUS‑DP communication tasks independently. It offloads communication workload from S7‑400 CPU so that the central processor concentrates on logic calculation and process control. This module works as PROFIBUS‑DP master station or DP slave station to connect ET200M, ET200SP distributed I/O modules, variable‑frequency drives, HMI panels, S7‑300 PLC, S5 legacy PLC and other DP‑compliant field‑bus devices. It supports DPV1 extended functions, S7 communication, PG‑OP routing and open user‑data exchange. It is widely adopted in PCS7 process‑control projects, petro‑chemical plants, thermal‑power stations, automobile welding workshops and cement production lines. Hardware configuration and online diagnostics are completed by STEP7 software. It gets DC5‑V power supply through S7‑400 back‑plane bus without extra external power supplydocs.rs-on….
2. Main Functions
- PROFIBUS‑DP Master‑Station Operation
As a DP master station, it can connect up to 125 DP slaves. Total input and output address space reaches 4096 bytes respectively, and each single slave supports maximum 244‑byte input and output data. It supports DPV1 services for acyclic data exchange such as parameter reading and diagnosis for drives and safety‑related equipmentdocs.rs-on….
- PROFIBUS‑DP Slave‑Station Mode
It can run as DP slave to exchange data with upper‑level DP master controllers like S7‑400H and S7‑1500‑series CPUs to realize cross‑level PLC‑to‑PLC data transmission.
- Open User‑Data Communication
It provides up to 32 communication connections via SEND‑RECEIVE function blocks. Each connection supports maximum 240‑byte user data. It realizes data exchange with old‑generation S5‑PLC systems for equipment‑renovation projectsdocs.rs-on….
- PG‑OP Routing Function
Programming laptops and HMI panels can access all DP‑slave stations and S7‑400 CPU through this CP module. Engineers download programs, monitor runtime data and carry out fault diagnosis without additional external PROFIBUS adapters.
- Comprehensive Diagnostic Function
Multiple LED indicators including SF, RUN and BUSF display module status, bus breakdown and hardware faults. Detailed diagnostic information can be uploaded to S7‑400 CPU and read by STEP‑7 for fast troubleshooting.
- Galvanic Isolation Design
Built‑in electrical isolation between S7‑400 back‑plane bus and RS‑485 PROFIBUS‑DP circuit can restrain electromagnetic interference from high‑power motors and servo‑drives.
- Multi‑Module Deployment
One S7‑400 station can install up to 10 pieces of CP443‑5 modules to build several independent PROFIBUS‑DP networks for large‑scale distributed‑control systemsdocs.rs-on….
