1. Equipment Introduction
The GCAN-204 module is an industrial grade Modbus RTU to CAN module that integrates one standard serial port and one standard CAN bus interface. The serial bus end of the GCAN-204 module has integrated the Modbus RTU protocol. With the GCAN-204 module, users can connect devices that originally used the serial bus for communication (Modbus RTU protocol) to the CAN bus communication interface without changing the original hardware structure. This allows devices that use the Modbus RTU protocol for communication to quickly connect to the CAN bus and form nodes in the CAN bus network.
When the GCAN-204 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-204 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-204 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.
