PROFIBUS DP master to MODBUS RTU/TCP slave protocol converter gateway

The PROFIBUS master station communication management machine can realize the conversion of PROFIBUS interface slave station equipment to MODBUS interface.

Provide PROFIBUS slave station equipment integration solutions for distributed control systems (PLC, DCS, industrial computers). PROFIBUS master station equipment is responsible for connecting PROFIBUS-DP slave stations from various manufacturers around the world to the MODBUS network, providing a global PROFIBUS system User Services.

product model :

1. HT3S-DPM-MTP: PROFIBUS DP master station (multiple DP instruments, controllers) to MODBUS TCP slave station (server/client)
2. HT3S-DPM-MDN: PROFIBUS DP master station (multiple DP instruments, controllers) Controller) to MODBUS RTU slave station (RS485/RS232 interface, supports MODBUS RTU standard protocol)
3. HT3S-DPM-RSE: PROFIBUS DP master station (multiple DP instruments, controllers) to RS485/RS232 slave station (customized protocol)

Features:

1. The PROFIBUS-DP/V0 protocol complies with GB/T 20540-2006: Fieldbus for measurement and control of digital data communication industrial control systems Part 3: PROFIBUS specifications;
2. PROFIBUS-DP serves as the master station, with a maximum baud rate of 12M ;
3. PROFIBUS-DP serves as the master station, and the maximum number of PROFIBUS-DP slave stations that can be connected is 32, and the communication data of a single PROFIBUS-DP slave station does not exceed 244 bytes;
4. MODBUS-TCP serves as the slave station, and uses standard RJ45 connection Mode;
5. MODBUS-TCP as a slave station, supports function codes 01H, 03H, 04H, and 10H.
6. Power supply: DC 24V/200mA (18V~30V available). It is recommended to connect the protective ground PE during use;
7. Working environment temperature: -40~85℃, humidity ≤95%;
8. Protection level: IP20;
9. The maximum baud rate can reach 12M for stable operation;
10. A maximum of 126 DP slave stations can be connected. It is recommended to install a repeater for every 32 DP slave stations to ensure the bus signal quality; Due to the limit of the total internal memory capacity, if each If the data volume of each station is large, the number of DP slave stations may be reduced.
11. Adopts standard 9-pin D-shaped PROFIBUS socket (hole). It is recommended that users use standard PROFIBUS plugs and standard PROFIBUS cables. For PROFIBUS installation specifications, please refer to the relevant PROFIBUS technical standards.
12. As the master station of Profibus, the gateway reads the data from the slave station and stores it in the Profibus input data area. After the data is exchanged, it is cached in the MODBUS-TCP input data area. The MODBUS-TCP master station reads these data through the 03H command;
13. The gateway As a slave station of MODBUS-TCP, the MODBUS-TCP master station writes data into the MODBUS-TCP output data area through the 10H command. After data exchange, it is cached in the Profibus output data area and transmitted to the Profibus slave station through the Profibus bus;

Case application diagram

1. HT3S-DPM-MTP is a independently developed communication gateway with PROFIBUS-DP master station function. The main function of this product is to connect various PROFIBUS-DP slave stations to the MODBUS-TCP network. Generally, the MODBUS-TCP network is DCS, PLC, industrial computer, ordinary PC, etc. This gateway is connected to the Profibus bus as the master station and connected to the MODBUS-TCP bus as the slave station. 

2. Use the PROFIBUS master station gateway to network PROFIBUS inverters and other equipment, and connect to the host computer control system through MODBUS TCP for a power plant control solution.

3. The solution for industrial computers to read PROFIBUS slave stations: Connect the on-site PROFIBUS interface frequency converters Siemens MM440 and ABB ACS510 and PROFIBUS distributed IO slave station ET200S to the MODBUS network to realize the monitoring of PROFIBUS slave stations by industrial computers.
