2.6 IO-Link Interface

The EVM contains an industry standard 4-pin M12 connector (J2) with a Class A 2-channel configuration implementing one IO-Link communication channel and one digital input or output channel as well as a screw terminal block (J1) for bare wire connections or external loads.

The TIOL221 power supply input (24V typical) pin "LP" has been labeled "L+_24V" on the board to help clarify that this is the +24V Power Supply.

Likewise the TIOL221 ground pin "LM" has been labeled "GND" on the board to help clarify that this is the Ground pin of the Power Supply.

The TIOL221 has separate digital output "DO" and digital input (DI) pins, but only one mode can be used at a time. Therefore, the DO and DI pins are connected together to allow either mode configuration to be used with the same hardware configuration and cabling.
