Product details

PB-OEM1 series embedded PROFIBUS board, dual port RAM data exchange mode, 8-bit data bus and read-write signal lines, dual isolated power supply 5V power supply. Suitable for on-site equipment with high-speed data communication requirements, such as frequency converters, servo controllers, encoders, etc PLC、 Robots, CNC, etc.

Parallel port data reading and writing: The CPU of the user's product completes data reading and writing with the dual port RAM (1K/2Kbytes) of the OEM1 interface board through the 8-port data bus. The OEM1 interface board automatically converts the dual port RAM data into PROFIBUS-DP protocol messages and communicates with the main station.
● High speed data conversion: The OEM1 board's PROFIBUS interface supports adaptive 9.6K-12M baud rates, with the fastest data update cycle (between the DP interface and the parallel data bus) being less than 1ms.
Scope of application: It can be widely used in various products, such as frequency converters, motor starting protection devices, intelligent high and low voltage electrical appliances, power measurement devices, various transmitters, intelligent on-site measurement equipment and instruments, etc.
Evaluation board and technical materials: The PB-OEM1 product manual includes the PB-OEM1-E schematic diagram of the evaluation board, dual port RAM communication protocol, communication program C source code, external dimensions and connector size diagrams, 40 pin connector pin definitions and instructions, etc. All materials can be downloaded online.
PROFIBUS slave interface; 9.6K~12M adaptive;
● Supports all DP/V0 functions: external diagnosis, synchronization, freezing FAIL-SAFE;
● Support DP/V1-MSAC1 and DP/V1-MSAC2 functions;
● Support IM device maintenance function (slot: 0, index: 255, subidex: 65000);
● Independently set the length of large PROFIBUS IO data, with a maximum input of 244 bytes and output of 244 bytes;
The maximum length of user diagnostic data is 244 bytes;
The maximum length of user parameter data is 244 bytes;
The maximum user configuration data length is 200 bytes;
DPV1 slot - number of indexes: maximum of 12;
DPV1 slot - Index data length: maximum of 240 bytes;
The maximum number of connection channels supported by DPV1/MSAC2 is 3;
Data interface: 8-bit data bus, 2KB dual port RAM communication (maximum 55ns read/write cycle);
The interface board and user board exchange data between the dual port RAM through mutual interruption and hardware handshake, ensuring real-time and complete data exchange (consistency); The data exchange between the interface board and the user template has CRC checksum to ensure data security;
Two sets of 5VDC: VCC/GND-150mA and 5V/0V-100mA, need to be powered by the user board;
Working environment temperature: -20~55 ℃; Relative humidity at work: 5-95%;
● Dimensions: 50 mm × 70 mm;
● Socket: 2 × 20+2 × 5 pin spacing 2.0mm socket.

Project Name: Application of Frequency Converter from a Foreign Manufacturer
Product used: PB-OEM1-DPRAM
Connected product: frequency converter
Implementation function: Enable the frequency converter to be directly connected to the PROFIBUS DP bus, achieving workshop level monitoring of the frequency converter.
Effect analysis: Compared to ordinary serial communication, using a bus interface has greatly improved the transmission speed and anti-interference performance of the device.
