Performance Comparison of PROFINET and PROFIBUS

Performance Comparison of PROFINET and PROFIBUS

PROFINET and PROFIBUS are two fieldbus systems introduced by the PNO organization. There is no comparability between the two; PROFINET is based on industrial Ethernet, while PROFIBUS is based on RS485 serial bus. The protocols of the two are completely different due to the differing media, with no connection between them. However, both have excellent … Read more

PROFIBUS Fault Diagnosis

PROFIBUS Fault Diagnosis

Fault Diagnosis When S7-1200 communicates as a DP Master, the CPU does not stop and does not require downloading the organization block when a DP slave is lost. There are several methods for diagnosing faults in PROFIBUS DP: 1. Through the Indicator Lights on the Module The DIAG light on the front panel is green … Read more

Introduction to PROFIBUS Connection Debugging Cases

Introduction to PROFIBUS Connection Debugging Cases

PROFIBUS is an international, open, fieldbus standard that is independent of device manufacturers. The transmission speed can be selected from 9.6 kbaud to 12 Mbaud, and when the bus system starts, all devices connected to the bus should be set to the same speed. It is used for factory automation at the workshop level for … Read more
