In industrial automation and communication systems, reliable network connections are the cornerstone of ensuring efficient and stable data transmission. The CP 5613 A2 and CP 5614 A2 communication processors launched by Siemens are designed specifically for integrating personal computers (PCs) or programming devices (PG) into PROFIBUS networks. They are key components for building distributed control systems (DCS) and implementing device level data acquisition. This article provides a comprehensive and in-depth analysis of these two communication processors based on official operating instructions (C79000-G8976-C301-02, 12/2012), covering product overview, installation configuration, technical specifications, and compliance certification. The aim is to provide a detailed and reliable reference manual for automation engineers, system integrators, and technical maintenance personnel.
Product Overview and Components
CP 5613 A2 and CP 5614 A2 belong to the SIMATIC NET communication processor family and use the short PCI card format, suitable for industrial PCs or workstations with standard PCI or PCI-X slots. The standard supply includes the communication processor itself, SIMATIC NET software CD, and license certificate. Users need to verify the integrity of the packaging upon receipt.
The core function of both processors is to provide an efficient PROFIBUS interface, support a full range of data transmission rates from 9.6 kbps to 12 Mbps, and have the ability to automatically adapt to bus clocks (up to 66 MHz). The main difference lies in the number of interfaces and working mode:
CP 5613 A2: Equipped with a PROFIBUS interface, it can operate as a DP master or DP slave. As the master station, its DP Base function optimizes high-speed access to up to 124 DP slave stations and ensures data consistency.
CP 5614 A2: In addition to all the functions of CP 5613 A2, an additional PROFIBUS interface is provided. This enables it to operate simultaneously as a DP master on one interface and as a DP slave on another interface, providing a hardware foundation for building layered or redundant PROFIBUS network architectures. The data transmission mechanism controlled by its program supports flexible exchange of data between the master and slave modules.
On the appearance of the device, CP 5613 A2 is equipped with a yellow/green status LED and a PROFIBUS interface (D-Sub 9-pin female head). CP 5614 A2 is equipped with two interfaces, labeled as master interface and slave interface, sharing the same set of status LEDs. Its pin definitions comply with the standard PROFIBUS RS-485 specification, where pins 3 and 8 are signal lines (B and A) and provide a set of isolated 5V/90mA power outputs (pins 5 and 6) that can be used to power external terminal resistors or simple devices.
Safety regulations and requirements for qualified personnel
Siemens emphasizes the importance of safety and standardized operations at the beginning of the document. The warning notification system is divided into four levels:
Danger: Failure to comply may result in death or serious personal injury.
Warning: Failure to comply may result in death or serious personal injury.
Caution: Failure to comply may result in minor personal injury.
Attention: Failure to comply may result in property damage.
All warnings related to personal safety are accompanied by safety warning symbols. Before installation and operation, all relevant warnings and safety instructions must be carefully read and followed.
Only qualified personnel are allowed to operate. Qualified personnel refer to professionals who, based on their training and experience, are able to identify risks and avoid potential hazards. In addition, Siemens products must be used correctly, i.e. only for applications described in the catalog and related technical documents. If using third-party products, Siemens recommendation or approval is required. Proper transportation, storage, installation, debugging, operation, and maintenance, as well as compliance with permitted environmental conditions, are prerequisites for ensuring safe and trouble free operation.
Detailed explanation of hardware installation
Hardware installation is the first step to ensure the stable operation of the communication processor and must strictly follow the regulations:
Safety preparation: It is necessary to operate with a complete power outage. Turn off the PC/PG and unplug the power cord to prevent the risk of electric shock.
Electrostatic protection: Communication processors belong to electrostatic sensitive devices (ESD). When operating, touch the grounded metal surface to release body static electricity. When holding the module, only touch the edges to avoid touching the pins or circuits. Tools should also undergo anti-static treatment.
Installation steps:
Open the computer case, find an empty PCI slot, and remove its cover.
Remove the communication processor from the anti-static packaging, insert it vertically and firmly into the PCI slot, ensure complete contact with the gold fingers, and secure it with screws to prevent poor contact due to vibration.
