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 GCAN-
IO-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. The GCAN-IO-8000 bus coupler not
only supports all types of CANopen communication, but can also be easily
applied to the manufacturer's specific CAN bus environment. In addition, the
firmware can also be upgraded through the configuration interface.
GCAN-IO-8000 bus coupler can connect all bus terminal modules. As far
as the user is concerned, there is no difference between the processing methods
of analog input/output signals and the processing methods of other types of
signals. The information in the process image area of the controller is displayed
in byte array format. According to different models, the analog quantity bus
terminal module register contains temperature range, gain value and
linearization characteristic curve.
GCAN-8000 Bus Coupler supports automatic configuration, and you do
not need to set parameters on the PC. When GCAN-8000 bus coupler uses
Modbus RTU communication, communication parameters can be configured
by RS232 interface.
1.2 Performance
●CANopen baud rate supports 1000k, 500k, 250k, 125k, 100k, 50k, 10k;
PDO mode supports synchronization, loop, event-driven, and polling;
The number of bus terminal modules is up to 32;
●Sending PDO (CANopen) is determined by the number of extended input
modules, and receiving PDO (CANopen) is determined by the number of
extended output modules
●Configuration mode is automatic configuration,expandedfreely
CAN bus interface is an open 4-pin terminal
