However, there is a fair amount of variation in the protocol itself and in its physical layer definition, which creates problems in multi-vendor applications. Profibus is a very robust protocol that was designed to automate entire plants. PROFIBUS has certain protocol features that let certain versions of it operate in multi-master on RS 485 which Modbus could be the only a single master. Profibus DP PROFIBUS DP (DP-Decentralized Peripherals) is used in machine automation and other discrete signal applications.

Modbus is a open protocol that was designed by Modicon. It is accepted as a defacto standard. It was designned for transmitting non-critical non-deterministic data bewteen PLC's.

It was designned for transmitting non-critical non-deterministic data bewteen PLC's. Profibus is a propriety protocol, which is "owned" by Profibus International organisation. Modbus can be used from a controller, or monitor to a smart device, controller, or monitor to a smart device from multiple vendors and for remote monitoring of information from a smart device. Profibus is not only more complicated to implement and use, but it also uses specialized characteristics which tie it to RS485. Profibus has certain protocol features that let certain versions of it operate in multi-master mode on RS-485, while Modbus could be only single master. However, Modbus can operate on Ethernet (including multiple masters) while Profibus can't (Profinet can, but Profinet is not the same as Profibus).
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. Note that Modbus is a protocol which defines frame structure for the messages to be transported over serial lines. RS485 defines electrical specifications. PROFIBUS vs Modbus.

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.

With Modbus, there are 90 members with the primary backer being Schneider, 1 test lab, and zero training centers. Primary backers of PROFINET include Emerson, Siemens, Phoenix Contact, and many more. In addition, as of 2019 there are over 60 million PROFIBUS nodes and over 32 million PROFINET nodes already in the market. PROFINET and Modbus Profibus ayrıca Modbus gibi bir master-slave tipi protokoldür, ancak çoklu master’lere izin vermek için ek bir jeton halka protokolü vardır. Ayrıca, Modbus’dan farklı olarak, tüm cihazlar ağa “katıldıkları” bir başlangıç dizisinden geçer. Her bir slave, güvenilir olmayan bir zamanlayıcıyı korur. PROFIBUS PA (Process Automation) is mostly used in industries such as water treatment, oil, gas, chemicals, etc.
