Modbus to DP Gateway realizes the conversion function from Modbus RTU to PROFIBUS DP, making multiple slave station devices that conform to Modbus RTU communication regulation access to PROFIBUS DPnetwork. Modbus can be as master or slave, and this function can be realized by a special function button.

Modbus to DP Gateway: G0306 gateway can realize interconnection from Modbus RTU device to fieldbus PROFIBUS DP, and protocol conversion between Modbus RTU and PROFIBUS DP/V0. The user can make multiple Modbus RTU devices access to PROFIBUS DP network only by GSD file configuration.

24V DC power supply, standard PROFIBUS DP interface, rapid to diagnose device working state by indicator lights, easy to use.

G0306 has combined high reliability and flexibility, being indispensable internet tool of all industries of system integrators and plant operating personnel.

Modbus Gateway Working Principle

G0306 Modbus to DP Gateway supports both Modbus RTU and PROFIBUS DP. It is PROFIBUS DP slave device. when serving as Modbus master (G0306-MS), it can connect at most 31 Modbus slave station into PROFIBUS PA network theoretically (it should be 485 bus environment, and we suggest less than 10 Modbus slave device to ensure communication quality)

Gateway as Modbus Master(G0306-MS) 

Working mechanism of G0306 Modbus to DP gateway MS is by model configuration to reaize data conversion from Modbus data to DP data. Each module can configurate one Modbus message. There are totally 39 slots and 209 modules. Among them, 1 and 2 slot has fixed function. There are another 37 slots avalible. Each slot can configurate one module, which means it can configurate at most 37 Modbus messages.

Q: Can I get a free electronic manual?

A: Yes, if you want it, please contact us.


Q: How many slots and modules does G0306 Modbus to DP Gateway have?

A: G0306-SS has 20 slots and 67 modules in all.


Q: How do slots and modules work?

A: Among them, slot 1 and 2 has fixed function and there are other 18 slots can be used. Each slot can configure one module. That is to say at most 18 kinds mapping relation from Profibus input output relief area to Modbus storage area can be built.


Q: Can you provided OEM service?

A: Yes, we can, such as communication board, we can also provided fieldbus development toolkit.
