The CM 4x IO-Link communications module enables data exchange with up to 4 external IO-Link devices via one 3-wire cable each. Comprehensive parameterization options make it possible to adapt the controller flexibly to the communication partner. Thanks to the compatibility of IO-Link with standard sensors, commercially available sensors in accordance with IEC 61131 Type 1 can also be operated on the IO-Link master.
