Follow the “Automation Control System Communication” public account to learn about the principles of automation control systems and master knowledge of automation control systems. Click the blue “Automation Control System Communication” above to follow us. In DCS systems, the Modbus communication protocol is often heard of, while Siemens’ PLC often encounters the PROFIBUS communication protocol. … Read more
In the field environment of Profibus, we use a variety of systems, and the devices we face interference from are diverse, so the sources of interference are also varied. Many failures caused by interference are more difficult to troubleshoot than other faults. Before troubleshooting interference failures, we need to understand the types of interference. In … Read more
In the field environment of Profibus, the systems we use are diverse, and the devices we are interfered with are varied, so the sources of interference are also peculiar. Many failures caused by interference are more difficult to troubleshoot than other failures. Before eliminating interference faults, we need to understand the types of interference. To … Read more

1. Basic Properties of PROFIBUS PROFIBUS specifies the technical and functional characteristics of the serial fieldbus system. Through this system, distributed, digital field programmable controllers can be networked from the lower level (sensor, actuator level) to the middle level (unit level). PROFIBUS is divided into master and slave stations. > Master Station The master station … Read more
When mentioning Siemens’ communication, we must talk about PROFIBUS. Are you familiar with it? PROFIBUS is used in what ways? PROFIBUS supports master-slave mode as well as multi-master and multi-slave operating modes. In a multi-master environment, the control of the bus is determined by a token-passing method among the masters; once control is obtained, the … Read more
Testing and Measurement Tools 1. Handheld Devices Handheld devices are specially developed for testing PROFIBUS cables with RS 485 interfaces. For example, Siemens BT200 (recommended) and ComSoft Nettest II. Handheld devices can test the installation, as well as check the PROFIBUS cables and stations. To use the handheld device, it must be connected to the … Read more
