Modbus and profibus each have strengths, and there is some overlap as to what each of them is capable of. Some people, however, consistently prefer to use modbus over profibus. Modbus was originally designed in the mid 70’s and was a proprietary protocol for Modicon. The company published it royalty free before finally making it an open protocol.

I would class Profibus DP as a fieldbus, like DEvicenet, or CanOpen. Modbus TCP/IP was developed to take advantage of the benefits of an Ethernet network. Our very own Kyle Yost, Design Engineer, explains: “Modbus TCP/IP is basically the Modbus RTU protocol using the TCP interface in an Ethernet network. The Modbus data structure is defined using the application layer used in the TCP/IP protocol. The first SE gateway, the 5204SE-MNET-PDPMV1 Modbus TCP/IP to PROFIBUS DP-V1 Master gateway, easily turns a Modicon M340 or a Quantum Programmable Automation Controller (PAC) into a PROFIBUS DP-V1 Master.

The profibus and Modbus are enhancement to previous interface standards. These protocols defines real time communication between masters of bus, distributed sensors and actors. They are used for low transmission volumes and low latency applications.

Profibus vs modbus

Profibus and Modbus are two of the most common industrial fieldbus protocols in use today. Even though they share certain characteristics Modbus TCP server to PROFIBUS DP Master Simple connection of PROFIBUS DP Slave devices to Modbus control systems via internal I/O mapping With mbGate DP it is possible to integrate one PROFIBUS DP segment into Modbus TCP control systems. It acts as Modbus TCP Server and PROFIBUS DP Master.

Le protocole Modbus est une structure de communication conçue pour récupérer les PROFIBUS (Process Field Bus) PA est un protocole de communication 

Note that Modbus is a protocol which defines frame structure for the messages to be transported over serial lines. RS485 defines electrical specifications.

Out of these the Profibus DP is more commonly used by industries while the Profibus PA is more application specific and is hence lesser used. Profibus DP is meant to be used to control and operate sensors and actuators through a centralized platform for automation applications in production industries and factories.
