Product Description

Siemens Communication Modules (CMs) or Communication Processors (CPs) are used to add additional interfaces to a central controller or a decentralized station. While a CPU may have integrated ports, these modules provide the flexibility to connect to different network types or to increase the number of available ports for network isolation. They handle the protocol stack independently of the CPU’s main processing cycle, ensuring that intensive communication tasks do not degrade the performance of the control logic. These modules support a wide array of physical media, from twisted-pair copper to fiber optics.

Product Parameters

The technical specifications focus on data throughput, protocol support, and hardware interfacing:

• Interface Types: Support for Industrial Ethernet (PROFINET), Serial (RS232, RS422, RS485), and specialized fieldbuses.

• Protocols: Compatibility with various communication standards such as Modbus TCP/RTU, Point-to-Point (PtP), and various proprietary or open Ethernet protocols.

• Transmission Speeds: Data rates ranging from standard serial speeds up to Gigabit Ethernet, depending on the module’s performance class.

• Connection Capacity: Limits on the maximum number of simultaneous connections or nodes the module can manage.

• Integrated Services: Support for IT functions such as FTP/FTPS client/server, E-mail (SMTP), and Web server functionality.

Product Advantages

• Offloading the CPU: By processing communication protocols locally on the module, the CPU’s cycle time remains consistent and dedicated to time-critical control tasks.

• Network Isolation: Allows for the physical and logical separation of the factory floor network (OT) from the office or management network (IT), enhancing security and performance.

• Legacy Integration: Enables modern PLC systems to communicate with older, legacy equipment through serial or specialized fieldbus interfaces.

• Simplified Engineering: Modules are easily integrated into the TIA Portal, where communication parameters can be configured through graphical interfaces rather than complex manual coding.

• Advanced Diagnostics: Provides real-time information regarding network status, telegram errors, and connection health directly to the control system.

Precautions

• Power Consumption: Communication modules draw power from the backplane bus; users must ensure the power supply is sufficient for the total number of modules in the rack.

• Protocol Limits: It is essential to verify that the module supports the specific version or flavor of the protocol required by the third-party device.

• Termination and Shielding: For serial or fieldbus communication, proper cable shielding and termination resistors must be applied to prevent data loss due to interference.

• Security Settings: If the module is connected to an external network, security features such as IP access protection and encrypted communication should be enabled.

Product Applications

Siemens Communication Modules are essential for building integrated, data-driven automation environments:

• Inter-PLC Communication: Facilitating data exchange between different machines on a production line for synchronized operation.

• SCADA and HMI Integration: Providing high-speed data channels to monitoring systems and human-machine interfaces for real-time visualization.

• Third-Party Device Linking: Connecting the PLC to barcode readers, weighing scales, or printers via serial or Ethernet protocols.

• Remote Access and Telecontrol: Enabling remote diagnostics and maintenance via secure VPN connections or mobile networks for geographically dispersed assets.
