In this section you'll find several sets of downloadable files, ranging from simple forms to join PI to executables to help you engineer and commission PROFIBUS and PROFINET devices. Much of it is free, although to get some files you'll need to join PI to gain access. The 'key' icon tells you which file needs a password.
Back to download listIO-Link defines a fieldbus-independent communication interface for intelligent sensors and actuators in factory automation. The scope of this specification work focuses on the transmission physics (electrical and mechanical properties, topology), sensor/actuator communication with the IO assemblies, and a neutral data interface to the higher-level communication system. IO-Link allows an inexpensive point-to-point connection between sensor/actuator and the I/O assembly for the "last meter to the process". Diagnosis and parameter information between sensor/actuator and the automation system will be exchanged with IO-Link in addition to the measurement signal through the specified communication mechanism, thereby maximizing the performance of state-of-the-art intelligent sensors and actuators.
You will find the current specification on the IO-Link web site:
IO-Link Specification.
