GB/T 15969.9-2021 Programmable controllers—Part 9: Single-drop digital communication interface for small sensors and actuators (SDCI) (English Version)
This part of GB/T15969 specifies the single-point digital communication interface technology (SDCI) (commonly known as IO-LinkTM) for small sensors and actuators, which extends the digital input and output interfaces of IEC61131 2 to point-to-point communication connections . Using this technique, the
