In our PROFINET DCP overview, we discussed the ability to reset a device among other features. In this article, we’ll expand the discussion of this topic, covering the default reset and other reset modes. For users, taking extra care and doing a proper factory reset can save you time and headaches. For developers, this information may be helpful for your […]
We often get the question: Why doesn’t PROFINET use Dynamic Host Configuration Protocol (DHCP) for IP address assignment as DCHP is used extensively in the office? Answer: DHCP could be used, optionally, but there are some differences you should know between DHCP and PROFINET DCP.
The number one rule-of-thumb, which you should never forget when commissioning a PROFINET system: make sure to assign the device name from your engineering tool (or setup auto commissioning). Here is the PROFINET Naming Convention list to help you out.
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). […]

A great advantage of PROFINET over some other competing automation networks is the included support in the specification of wireless technology and most importantly the Industrial features available. This opens up a wide variety of applications which are very difficult or impossible when it comes to normal copper cabling. Some of these applications might be Automated Guided Vehicles (AGVs), slip rings, a rough environment, shipping and […]
PROFIsafe, PROFIdrive, PROFIenergy… these terms are pretty common in the PI world. How are they used in the real world? And how do they actually work? What is the definition of an application profile?
What is PROFIdrive? PROFIdrive is a vendor-neutral application profile from PROFIBUS and PROFINET International (PI) which is focused on drives, encoders, motors, and their applications, which range from simple to very demanding motion control tasks. It supports both PROFIBUS and PROFINET technologies. PROFINET allows scalable update times starting from 31.25μs and a jitter of less than 1μs for the most demanding […]
When we talk about PROFIdrive, it’s always fun to use high-speed servos, CNC milling, and 3-D printing as application examples. But those applications are only some of the ways we use motors in the real world. Every day, millions of motors and drives are dedicated to pumping, blowing, and turning at a fixed speed. That’s what Application Class 1 drives […]
