The I-7242D is one of CAN bus products in ICP DAS. The device allows a master located on a DeviceNet network to enter into a dialogue with the slaves on a Modbus RTU network In DeviceNet network, it is a Group 2 Only Slave device, and supports “Predefined Master/Slave Connection Set”.
It is a general protocol converter operating in a way that is transparent to the user. In addition, we also provide the utility software for users to configure the I-7242D,s parameters and build the EDS file. Users can easily apply Modbus RTU devices in DeviceNet applications with the I-7242D.
