S7-1200 acts as a DP Master during communication. When a DP slave is lost, the CPU does not stop, nor is it necessary to download an organization block to the CPU. For fault diagnosis of PROFIBUS DP, there are several methods: 1. Through the Indicator Lights on the Module The DIAG light on the front … Read more
PROFIBUS Transmission Technology (Physical Layer) and DP Communication In the ISO/OSI reference model, the first layer defines the “physical” methods of data transmission. This includes encoding types and the transmission standards used (e.g., RS 485). PROFIBUS provides various transmission technologies for the first layer: RS 485, RS 485-IS, MBP, and fiber optic transmission technology. Traditional … Read more
