PROFIBUS’s success in the industrial controls universe is partly due to its wide array of diagnostic capabilities. Every PROFIBUS slave device must support, at a minimum, 6 bytes of standard diagnostic data. This data is defined by PROFIBUS and PROFINET International and reports the device state, its controlling master and whether the device has any extended diagnostic data (additional fault information) available.

Did you know that IO-Link wiring needs only 3 wires of a parallel cable instead of 19?

The simple motto 3 instead of 19 wires vividly describes the saving potential of IO-Link compared to conventional wiring. The user benefits are made clear using the example of a passive distributor with 8 M12 connections. For comparison purposes, an IO-Link input module that can be connected to any IO-Link master is used.

One of the many reasons for PROFIBUS’ success over the years has been the ability of PROFIBUS diagnostics to pinpoint instrument problems in a running system. This tech tip’s purpose is to give you a better understanding of the mechanics of how PROFIBUS diagnostics work and to show how the information is reported.

Did you know that the benefits of IO-Link are built on three pillars?

The tremendous success of IO-Link rests on three pillars whose value is clearly recognized no matter the industry sector: simplified installation, simplified parameter assignment, and diagnostics.

Did you know that IO-Link allows automatic parameter assignment by the PLC?

With IO-Link, the parameter assignment of the devices is stored in the higher-level automation system and is transferred automatically if a device is replaced. Moreover, the PLC can access, read, and write any parameters during operation. (more…)
