Introduction:
The I-7243D is one of CAN bus products in ICP DAS. It not only supports VxComm and Modbus RTU/TCP transfer function, but also provides DeviceNet and Modbus/TCP gateway function. I-7243D solves a mission-critical problem: connecting an existing DeviceNet network to Ethernet-base PLCs and PC-based configuration and monitor system. It enables DeviceNet networks to be coupled together over the Internet/Ethernet, whereby remote monitoring and control is possible. On DeviceNet network, it provides “Predefined Master Connection Set”, and supports Group 2 only Server functions to communication with slave devices. On the Ethernet network, it acts as a Modbus TCP server. Users can use Modbus TCP class 0, class 1 and partial class 2 function to communicate with I-7243D. In addition, we also provide friendly utility software for users to configure their device parameters of the I-7243D.
