Networking and Data Exchange in Industrial Ethernet Applications

IMC Test and Measurement has announced that a Profinet interface is now available for the imc CRONOS measurement system; the company says a user can network devices of its CRONOS family of measurement systems with industrial controllers, PLCs or tooling machines. Expansion through the new Profinet interface transforms imc CRONOS into a Profinet IO device, perfect when using demanding applications in process and test stand automation, machine monitoring and condition monitoring.



In automation, field buses exchange machine parameters, control commands, status information, measurement values and alarms. Profinet has established itself in these areas as a communications standard for industrial Ethernet with real-time capabilities. As the successor to Profibus (RS485), Profinet is network-based (100 Mbit/s) and is now available as an interface option for imc CRONOS.


The PROFINET IRT Interface allows an imc CRONOS measurement system to be networked in applications for process and test stand automation or for condition monitoring of machines and industrial installations. The interface enables bidirectional data exchange in real-time and has been implemented following conformance class CC-C. It thus supports real-time functionality, mainly through mechanisms of synchronization (PTP) and reserved bandwidth (IRT; isochronous real-time). As a result, imc CRONOS becomes a fully-fledged IO device physically coupled to the control network through two dedicated RJ45 terminals.


imc CRONOS is a modular, high-end measurement device platform for physical quantities. It has been on the market for over 10 years and since then been continuously evolved and refined. imc CRONOS devices are designed for measurement tasks that are demanding and require multiple channels. As a highly flexible system for measurement, data acquisition, control and automation solutions, imc CRONOS is used in various stationery and mobile applications. Use can range from single test stands to complete test facilities or condition-monitoring of machines in stationary industrial applications.
