PROFINET, PROFIBUS, and IO-Link news from around the world

Guideline for Developing a PROFINET Product

The new guideline, "Recommendation for Design and Implementation of PROFINET Devices," addresses technological aspects as well as organizational issues such as certification and marketing when developing a PROFINET device. It guides vendors through this process from initial questions to market launch of a product.

PROFINET Device / Controller Integration + PROFIdrive

To assist manufacturers of automation devices in adding PROFINET to their products, many tools are now available. One is a PROFINET driver for controllers, and a second is a chip for devices. Both are from Siemens. A third, from Hilscher, also includes PROFIdrive controller functionality.

IO-Link: Did You Know

Did you know that IO-Link enables devices that were previously inconceivable? IO-Link sets new standards for the design of input/output modules. Whether integrated in the control rack or as a fieldbus module, one and the same module can process a wide range of signals. IO-Link masters can replace both binary and analog inputs and outputs. This facilitates spare parts management and enables flexible machine design. There is no longer a need for so many different types of modules.

Tech Tip: Suite and Simple Network Management with PROFINET

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’.

IO-Link: Did You Know?

Did you know that IO-Link is backward compatible with binary sensors? The IO-Link communication interface is standardized in international standard IEC 61131-9. One of the initial goals of the multi-company standardization initiative was to create an interface that takes into consideration the existing architectures and the typical connection level in the lower field level. The point-to-point connection familiar there was simply taken over in IO-Link, complete with the standard cabling.

Is Profibus or 4-20mA More Accurate?

When it comes to transmitting process variables, 4-20 mA is by far the most popular method. Digital fieldbuses such as PROFIBUS or PROFINET, however, are said to be more accurate and generally better than 4-20 mA. What isn’t discussed very often, however, is the extent of how much more accurate they are. This topic is the elephant in the control room.
