One of the strengths of fieldbuses and industrial Ethernet protocols in general, and Profibus and Profinet in particular, is the diagnostic information. This diagnostic information can prevent downtime and accelerate Profinet troubleshooting. First, an explanation of the technologies: Profibus and Profinet International (PI) created, support, and maintain the Profibus and Profinet standards. Both specifications are part of IEC 61158. Profibus […]
In the automation environment of today and tomorrow, end users need a system which is built with effective diagnostic capabilities and is easy to manage at both the network and application levels for minimum downtime and increased productivity. PROFINET should be your network of choice because it has best in class diagnostic mechanisms which are in short: ‘suite and simple’. IT […]
What is Simple Network Management Protocol? SNMP is a protocol which has crossed over from information technology (IT) to PROFINET networks. Most PROFINET devices support it for network diagnostics and measurement through PROFINET’s coexistence with standard IT protocols and industrial Ethernet. Information can be gathered from the network nodes such as statistics of the network load (bandwidth utilization), errors from faulty packets, or status of the […]
In Part One of this series, we discussed how PROFINET leverages IT protocols such as Simple Network Management Protocol (SNMP), File Transfer Protocol (FTP) and Hyper Text Transfer Protocol (HTTP) to provide easy configuration and diagnostics over the network. Now in part two, we’ll cover PROFINET device naming, PROFINET Discovery and Configuration Protocol (DCP), and Link Layer Discovery Protocol (LLDP). […]
