I. Product Overview

Allen-Bradley 1747-BSN is a DeviceNet communication module designed for the SLC 500 series PLC systems. In the industrial automation network architecture, it plays an important bridging role, enabling bidirectional data communication between SLC 500 series PLCs and other devices on the DeviceNet network. It is a key component for building communication networks at the industrial field device layer. With its stable and reliable communication performance, this module is widely used in automated production lines in many industries such as automobile manufacturing, mechanical processing, logistics and warehousing, food and beverage, helping to realize collaborative work and data sharing between devices, and improving the intelligence and automation level of industrial production.

II. Functional Features

DeviceNet network compatibility: It fully complies with the DeviceNet communication protocol standards, can seamlessly access the DeviceNet network, and communicate efficiently with various DeviceNet devices on the network, such as sensors, actuators, frequency converters, and human-machine interfaces. This compatibility ensures that devices of different brands and types can work together in the same network, greatly improving the flexibility and expandability of industrial control systems.

Bidirectional data transmission: It supports bidirectional data transmission. It can not only send data such as control commands and parameter settings of the SLC 500 PLC to other devices on the DeviceNet network to realize remote control of these devices, but also receive status information, operating data, fault alarms, etc. from other devices and feed them back to the PLC, providing a basis for the logical control of the PLC and forming a complete control closed loop.

Flexible network configuration: It supports multiple network configuration methods. Users can set parameters and configure the network of the module through RSLogix 500 programming software or special DeviceNet configuration tools (such as RSNetWorx for DeviceNet). For example, the node address of the module and the communication baud rate (supporting 125kbit/s, 250kbit/s, 500kbit/s) can be set to adapt to industrial network environments of different scales and communication requirements.

Powerful diagnostic function: It has rich diagnostic capabilities and can monitor the working status of the module itself and the network communication status in real time. Through the LED indicators on the module (such as power indicator, communication status indicator, fault indicator, etc.), operators can intuitively know whether the module is normally powered, whether the communication is smooth, and whether there is a fault. At the same time, the module can also upload detailed diagnostic data to the PLC or upper computer, facilitating technical personnel to quickly locate and troubleshoot network faults and reduce system downtime.

Reliable communication guarantee: Adopting an industrial-grade design, it has strong anti-electromagnetic interference ability and anti-vibration and impact performance, and can maintain a stable communication connection in harsh industrial environments. In addition, the module also supports the verification function of communication data to ensure the accuracy and integrity of data during transmission, effectively avoiding equipment misoperation caused by data transmission errors.

Convenient installation and integration: It adopts a rack mounting method compatible with SLC 500 series modules. The installation process is simple and convenient, and it can be quickly integrated with the SLC 500 series PLC system. The terminal design of the module is standardized, which is convenient for on-site wiring and connection, reducing the workload of installation and maintenance.

III. Technical Parameters

Communication parameters:
Communication protocol: DeviceNet (based on CAN bus technology).
Node address range: 0-63.
Communication baud rate: 125kbit/s, 250kbit/s, 500kbit/s, which can be set according to network requirements.
Maximum communication distance: Related to the baud rate, the maximum distance is 500m at 125kbit/s; 250m at 250kbit/s; 100m at 500kbit/s (using standard DeviceNet cable).
Supported I/O data length: The input/output data length can be determined according to specific configurations, and it can support a certain number of bytes at maximum (for example, input/output can each reach 128 bytes, subject to the product manual for details).

Electrical parameters:
Power input: Obtain 5V DC power through the SLC 500 backplane, with a typical current consumption of about 120mA (the specific value is subject to the product manual).
DeviceNet interface: Adopt a standard 5-pin circular connector (in line with DeviceNet specifications), supporting both bus power supply and external power supply (depending on the network configuration).
Isolation performance: Equipped with electrical isolation function, the isolation voltage can reach a certain value (such as 250V AC), effectively preventing external electrical interference from affecting the module and the PLC system.

Physical parameters:
Dimensions: Length about 160mm, width about 100mm, height about 150mm (compatible with other modules in the SLC 500 series), suitable for installation in standard racks.
Weight: About 0.5kg, light in weight, easy to install and carry.

Environmental parameters:
Operating temperature: 0℃-60℃.
Storage temperature: -40℃-85℃.
Relative humidity: 5%-95% (non-condensing).
Anti-vibration performance: 10-55Hz, amplitude 0.38mm.
Impact resistance: Peak acceleration 15g (duration 11ms).

IV. Working Principle

Data reception and processing: The 1747-BSN module receives data frames sent from other devices on the network through the DeviceNet network interface. These data frames contain device status information, measurement data, etc. The communication controller inside the module parses and verifies the received data frames, extracts valid data information, converts it into a format recognizable by the SLC 500 PLC, and transmits it to the CPU module of the PLC through the backplane bus.

Data transmission and conversion: When the SLC 500 PLC needs to send control commands or parameters to devices on the DeviceNet network, the CPU module transmits relevant data to the 1747-BSN module through the backplane bus. After receiving the data, the module packages and encodes the data according to the requirements of the DeviceNet protocol to form a standardized data frame, which is then sent to the target device through the DeviceNet network interface.

Network management and maintenance: The module has a built-in network management function, which can participate in the initialization of the DeviceNet network, device enumeration, baud rate negotiation and other processes. During network operation, the module monitors the network communication quality in real time. If abnormal situations such as communication errors and device offline are detected, it will promptly trigger corresponding fault indicators and feed back the fault information to the PLC, so that the system can take corresponding processing measures (such as alarm, shutdown, etc.). At the same time, the module also supports remote configuration and diagnosis. The parameters of the module can be modified through the upper computer software, and the operating status of the module and the network can be checked.
