Vhandy technology 1. Introduction 1.1 Overview GCAN-8000 Modbus I/O Coupler can be used to connect CAN bus system and distributed bus terminal module, and these terminal modules can be expanded in a modular way. A complete node consists of a bus coupler, 1-32 arbitrary number of terminal modules and a terminal module. Adopt GCANIO-8000 bus coupler, through GC-bus expansion technology, can establish I/O connection extremely conveniently, can connect 32 input/output terminal modules at most. The GCAN-IO-8000 CANopen bus coupler adopts the CAN bus protocol that conforms to the ISO 11898 standard....

Vhandy technology 2. Installation and usage This chapter introduces the method installation and wiring,the meaning of the indicator and the interface. 2.1 Fixed module The installation method of GCAN-8000CANopen bus coupler is shown in Figure 2.1 Figure 2.1 GCAN-8000 module installation Figure 2.2 GCAN-8000 module self-locking mechanism As shown figure 2.1, install the GCAN-8000CANopen bus coupler on the guide rail until the lock is stuck. The GCAN-8000 CANopen bus coupler has a self-locking mechanism that can effectively prevent equipment from falling. As shown figure 2.2, you can release the...

Vhandy technology bus terminal modules. When inserting bus terminal module, be sure to insert it along the groove on the right side of the existing module sequentially until the lock is stuck. At the right end of the entire node, you need to install terminal module. The terminal will guarantee the data transmission and power supply of the GC-Bus. When you assemble the nodes correctly, there is no obvious gap between the terminal modules. If the modules are not assembled correctly, the entire node will not operate normally. 2.2 Wiring method The power wiring as shown in figure 2.3. First, use...

Vhandy technology 3. Communication connection 3.1 Serial connection GCAN-IO-8000 CANopen bus coupler uses standard serial port level (RS232: ±3~15V), so this module can be directly connected to equipment with RS232 interface. The RS232 interface baud rate of the GCAN-IO-8000 CANopen bus coupler cannot be modified and is fixed at 19200bps. 3.2 CAN connection GCAN-IO-8000 connect to CAN-Bus as described in figure 3.1, CAN-H connect CAN-H, CAN-L connect CAN L to make communication. GCAN-IO-8000, must be installed two 120 ohms terminal resistance at the farthest end of CAN-Bus network; if the node...

The value of the terminal matching resistance is determined by the characteristic impedance of the transmission...

Vhandy technology 8000 module through the RS232 interface. The specific process is as follows: First, establish a serial port connection with a baud rate of 19200bps, configure the data bit and stop bit as none, 8, 1, and send a "help" command or "?" command through the RS232 interface, and then the RS232 interface will return to the configuration information. Please note that when sending the command, please add a carriage return at the end or select "Send New Line" in the software. Do not select "Hexadecimal Display" or "Hexadecimal Transmission" for display and transmission. You can send "setbaud=500000"...
