EPP6228-0022 | IO-Link master

The EPP6228 IO-Link module enables connection of up to eight IO-Link devices, e.g. IO-Link box modules, actuators, sensors or combinations thereof. A point-to-point connection is used between the module and the device. The EtherCAT P Box is parameterised via the EtherCAT master. IO-Link is designed as an intelligent link between the fieldbus level and the sensor, so that parameterisation information can be exchanged bidirectionally via the IO-Link connection. The parameterisation of the IO-Link devices with service data can be done from TwinCAT via ADS or very conveniently via the integrated IO-Link configuration tool. In addition to the IO-Link channels, the EPP6228 features eight digital inputs on pin 2 of the respective M12 socket. In the standard setting, the IO-Link channels C/Qx of the EPP6228 accept both IO-Link devices and standard sensors with 24 V DC.
