The I-7242D is a CAN bus product. The device allows a master located on a DeviceNet network to communicate with the slaves on a Modbus RTU network It is a Group 2 Only Slave device in the DeviceNet network. It supports “Predefined Master/Slave Connection Set.”It is a general protocol converter operating in a way that is transparent to the user. 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. |
