Exclusive support for the PROFIBUS DP protocol, strictly adhering to the IEC 61158 - 3 - 10 and EN 50170 standards. In Master mode, it manages network configuration, cyclic data polling from Slave devices, and acyclic parameterization commands. In Slave mode, it responds promptly to Master requests, ensuring seamless data transfer for real - time control applications. It also supports PROFIBUS MPI (Multi - Point Interface) functionality, enabling communication with legacy PROFIBUS devices.

All protocol operations support cyclic process data exchange, crucial for real - time control loops, and acyclic configuration/parameterization for device setup and maintenance. The card complies with PROFIBUS DP's master - slave communication model, ensuring reliable data transfer within the specified time - critical intervals.

Physical Form Factor: Complies with the standard PCI Express form factor, with dimensions optimized to fit into standard PCIe slots (1 - lane) of industrial PCs. Its compact and rugged design (approx. 120 mm × 68 mm × 18 mm) makes it suitable for space - constrained industrial control cabinets.

Power Requirements: Operates on a single +3.3 V DC supply (± 5%), directly sourced from the PCI Express bus. The typical current consumption is ≤ 800 mA, ensuring stable operation with standard industrial PC power supplies.

Integrated Memory: Equipped with 8 MB of SDRAM for high - speed data buffering during communication. This allows for efficient handling of large amounts of process data, ensuring smooth data flow between the host PC and the PROFIBUS DP network. Additionally, it has 4 MB of serial flash EPROM for storing firmware, enabling easy firmware updates and configuration storage.

Connector Interface:

PC Connection: Features a standard PCI Express edge connector, providing a high - speed, reliable connection to the host PC. The connector is designed to withstand the rigors of industrial environments, ensuring stable signal transmission.

PROFIBUS DP Connection: Utilizes a 9 - pin D - sub connector (RS - 485, galvanically isolated up to 1000 V DC for 1 minute), compliant with PROFIBUS DP standards. This connector supports twisted - pair cabling for differential signal transmission, minimizing electromagnetic interference (EMI) in factory settings.

Certifications: UL 508 certified for industrial control equipment, ensuring safe operation in industrial environments. CE marked for electromagnetic compatibility (EMC) per EN 61000 - 6 - 2 (industrial environment) and EN 61000 - 6 - 4 (generic immunity), validating its performance in harsh electrical environments.
