Guide for the standard mapping of IO-Link devices to the sercos automation bus is available. IO-Link is a low level, point-to-point communication interface technology for interconnection of binary and analog sensors and actuators. The user guide helps you uniformly connect and integrate sensors and actuators equipped with an IO-Link interface into a sercos system.
An IO-Link master can be established either as part of a modular sercos slave I/O device or as a stand-alone sercos III slave. The cyclic data of all inputs and outputs of IO-Link slaves are either transmitted completely within a cyclic IO container or alternatively as separate parameters. The sercos parameter channel can be used to execute acyclic read/write access with regard to the addressed IO-Link slave devices.
