Modbus to PROFIBUS PA Gateway G0307

G0307 (original model no. is NCS-MP105) is PROFIBUS /MODBUS protocol gateway, the address of the PROFIBUS-PA slave, MODBUS RTU master. It's a new product of our company and will be put onto the market soon.

Product Description

• G0307 is converter for interfacing Modbus- RTU instruments to a Profibus PA network.
• Support PROFIBUS DPV1 and PROFIBUS PA 3.01
• Support AI, AO, DI, DO standard function blocks
• Support GSD5.0 and standard EDD
• Support standard DD or EDD specification
• Electrical interface connected with MODBUS device supports TTL level, RS485 and RS232
• Able to provide 3.3V or 5V power supply output

NCS-MP105 is a converter device for MODBUS- RTU protocol to PROFIBUS PA protocol. It is able to integrate device/board with MODBUS communication interface to PROFIBUS PA bus system. Bus power supply is selected by NCS-MP105, and NCS-MP105 can provide power supply to the boards the user provides.

As a MODBUS host, NCS-MP105 communicates with the device with MODBUS-RTU interface, it can achieve read/write operation for MODBUS register data via PA transducer blocks, and convert MODBUS data to PA communication system via PA standard AI,AO,DI,DO function blocks.

NCS-MP105 Application:

• Gas detectors
• Analyzers
• Positioners
• Any smart device with MODBUS protocol
