Abstract IEC 61131-9:2022 specifies a single-drop digital communication interface technology for small sensors and actuators SDCI (commonly known as IO-Link™ ), which extends the traditional digital input and digital output interfaces as defined in IEC 61131-2 towards a point-to-point communication link for the exchange of complex data in both directions. This techno¬logy also enables the transfer of parameters to Devices and the delivery of identification and diagnostic information from the Devices to the automation system. |
