Product Overview
The Siemens 6AG1343-1EX30-7XE0 SIPLUS NET Communication Processor is a dedicated communication module for Siemens industrial automation systems. It handles network communication functions required for exchanging information between a control station and other connected devices.
In a distributed automation installation, the communication processor serves as the connection between PLC application data and the industrial communication network. Control information generated by the automation program can be transferred to another station, while information received from the network can be passed into the control system for further processing.
The 6AG1343-1EX30-7XE0 is part of the SIPLUS NET family. It is suited to applications where communication equipment forms part of an industrial control installation with demanding environmental requirements.
The module is relevant to networked PLC systems, machine communication, production-line coordination, and maintenance of existing Siemens automation installations.

Working Principle
The communication processor receives communication tasks from the automation system and manages the associated network data exchange.
The basic process can be represented as:
PLC Data → Communication Processing → Network Transmission → Remote Station
For incoming information, the process operates in the opposite direction:
Remote Station → Network Reception → Communication Processing → PLC Application
The exchanged information can represent machine status, process values, commands, operating conditions, or diagnostic information.
The communication processor therefore acts as a dedicated communication path rather than directly performing the control logic itself. The PLC CPU continues to execute the application program while communication processing is handled by the dedicated module.
Role in Industrial Communication
The 6AG1343-1EX30-7XE0 can be used as the network communication element of a distributed automation station.
| System Element | Function |
|---|---|
| 6AG1343-1EX30-7XE0 | Communication processing |
| PLC CPU | Executes control and application logic |
| I/O Modules | Interface field signals |
| Industrial Network | Transfers data between stations |
| HMI | Operator monitoring and control |
| Engineering Station | Programming and diagnostics |
| Remote PLC | Exchanges process information |
| Supervisory System | Handles higher-level monitoring |
A distributed architecture using dedicated communication hardware allows individual control stations to exchange selected information while retaining their local control functions.
Communication Data
Typical industrial communication tasks can involve several categories of information.
| Data Type | Example |
|---|---|
| Status Data | Machine running, stopped, faulted |
| Process Data | Measured values and operating parameters |
| Command Data | Start, stop, reset, mode selection |
| Diagnostic Data | Equipment faults and communication status |
| Production Data | Production counts and operating information |
| Control Parameters | Values used by connected automation stations |
The actual data structure depends on the application program and configured communication architecture.
Industrial Applications
| Application | Typical Use |
|---|---|
| Factory Automation | Distributed PLC communication |
| Production Lines | Exchange of machine status and process data |
| Machine Automation | Controller networking |
| Manufacturing Cells | Coordination between control stations |
| Process Equipment | Control and supervisory data exchange |
| Material Handling | Communication between distributed machines |
| Industrial Utilities | Networked automation equipment |
| Plant Automation | Distributed control architecture |
Installation and Maintenance
- Confirm the complete 6AG1343-1EX30-7XE0 model.
- Review the existing automation and communication configuration.
- Inspect the processor and associated connectors.
- Check network cables and connection points.
- Verify communication parameters.
- Isolate the automation station before replacing the module.
- Install the communication processor according to the applicable maintenance procedure.
- Restore network connections.
- Check processor diagnostics.
- Verify network communication.
- Test data exchange with the remote station.
- Confirm correct processing of received data.
- Monitor communication status during operation.
- Check for recurring communication errors.
- Document the final configuration.
For troubleshooting, separate the communication path into the processor, physical network, configuration, local PLC application, and remote device. This helps identify whether the problem originates from hardware or communication setup.

Technical FAQs
What type of automation architecture can use the 6AG1343-1EX30-7XE0?
It is suited to distributed automation architectures where a Siemens control station needs dedicated communication with other networked controllers or industrial equipment.
Does the communication processor execute the main PLC control program?
No. The central PLC CPU remains responsible for executing the application and control logic. The communication processor handles its assigned communication functions.
What happens when incoming network data reaches the PLC station?
The communication processor receives and processes the network information, after which the relevant data can be made available to the PLC application for control logic, monitoring, or further processing.
What should be compared before replacing an existing communication processor?
The replacement should be checked against the existing system configuration, communication requirements, network architecture, and PLC hardware arrangement. Matching the physical module alone is not sufficient for a communication-system replacement.
