Woodhead BradCommunications ™ Direct-Link ™ PROFIBUS-DP network interface card

Woodhead BradCommunications ™  Direct-Link ™  PROFIBUS-DP network interface card

This product is the industrial grade PROFIBUS-DP network interface card series launched by Woodhead (now under Schneider Electric). Its core positioning is to build a direct communication bridge between PC based control applications and I/O devices, supporting multiple hardware forms and operating systems, with high data throughput, flexible configuration, and ease of use. It is suitable for real-time data acquisition and control in industrial automation scenarios.

Core positioning and overall characteristics of the product

1. Core values

Communication intermediary: realizes direct connection between PC based control applications and PROFIBUS-DP I/O devices, supports deterministic I/O data acquisition, and meets real-time control requirements.

Low cost and high compatibility: It belongs to the entry-level industrial communication component, with high cost-effectiveness, modularity, and scalability. It can be easily embedded in computerized systems and adapted to industrial applications of different architectures.

2. Key common characteristics

Protocol support: Covering multiple PROFIBUS-DP protocol modes to meet the needs of different communication roles:

Basic support: PROFIBUS-DP V0 master station (Class 1/2), V0 slave station (active/passive mode);

Advanced support: Only PCI Universal models support PROFIBUS-DP V1 master station (Class 1/2).

Configuration and diagnosis: Equipped with one serial or Ethernet port (depending on the model) for remote configuration and diagnosis; Support automatic detection of network devices, store configuration parameters in Flash memory, and support automatic startup mode.

Performance optimization: onboard embedded communication module improves data throughput; Equipped with intelligent A.D.M (automatic dual port RAM mapping) mechanism, there is no need to configure I/O tags in the dual port RAM of the card, reducing the load on the host CPU; Provide additional functions such as device status, diagnostic information, process data read-write monitoring, software and hardware watchdog, etc.

Compliance: Compliant with RoHS standards (some models have new features), and a member of the PROFIBUS industry organization (PTO, PNO, France Profibus), with guaranteed protocol compatibility.

Protocol Function Details

1. PROFIBUS-DP main station features (all models support V0, PCU-DIPO additionally supports V1)

Main station type core function

DP-V0 Class 1 optimizes the I/O data exchange with the slave station to ensure real-time performance.

DP-V0 Class 2 implements slave diagnosis, reads slave I/O data, writes data blocks (Class 1/2), and terminates data block communication (Class 2).

DP-V1 Class 1/2 is only supported by PCU-DPIO, expanding the functionality of the main station and adapting to more complex communication requirements.
