1. Equipment Introduction
The GCAN-204C module is a national industrial grade module that integrates 1 standard serial port and 1 standard CAN bus interface, supporting bidirectional conversion between Modbus RTU slave protocol and CAN bus protocol. The serial bus end of GCAN-204C module has integrated Modbus RTU protocol and uses GCAN-204C Module, users can connect devices that originally used serial bus communication (Modbus RTU protocol) to the CAN bus communication interface without changing the original hardware structure, thus quickly connecting devices that use Modbus RTU protocol communication to the CAN bus and forming nodes in the CAN bus network.
When the GCAN-204C module reads data from Modbus, it will real-time load the data received on the CAN bus into the cache and wait for Modbus commands to read. After receiving the Modbus read command, the module will convert the specified CAN data and send it to the Modbus bus; When the module receives a Modbus data transmission command, it will directly process the Modbus data and send it to the CAN bus.
The GCAN-204C module is a key tool for industrial bus transformation and interconnection of multiple bus devices. At the same time, this module has the characteristics of small size, plug and play, and is also the best choice for existing system integration. The various bus interfaces of GCAN-204C are integrated with isolation protection modules to prevent damage to the module caused by instantaneous overvoltage and overcurrent. The use of DIN rail fixation makes it easier to integrate into various control cabinets.
