GCAN-PLC user manual
1. Introduction
1.1 Overview
GCAN-PLC-511 is a bus module controller integrated with PLC function.
It has the characteristics of compact, cost-effective, can be used to connect the
CAN-Bus system, Modbus system and distributed bus terminal module, and
these terminal modules can be expanded in a modular way.
A complete control system consists of a bus module controller (GCAN-
PLC-511),1-32 arbitrary number of GC series terminal modules (GC-1008,
GC-3804, etc.) and a terminal module.
The GCAN-PLC-511 supports automatic configuration. You do not need
to set parameters on the computer. The controller will automatically assign the
I/O interface according to the positional relationship of the inserted terminal
module.
The GCAN-PLC-511 is programmed according to the IEC 61131-3
standard using the OpenPCS programming system. OpenPCS programming
system provides a variety of debugging features (such as breakpoints, single-
step, monitoring, etc.) to make debugging easier. The GCAN-PLC-511
configuration/programming interface is a Micro-USB interface that can be used
to load PLC programs.
The GCAN-PLC-511 complies with the ISO 11898 CAN bus protocol.
Support CANopen/ Modbus RTU/ Modbus TCP communication protocol and
can be used as CANopen/ Modbus RTU/ Modbue TCP master or slave.
GC series programmable controller expansion module currently includes:
digital input expansion module, digital output expansion module, analog input
expansion module, analog output expansion module, Pulse input and output
module, communication port expansion module (RS232/485, 4G, Bluetooth,
WiFi, Zigbee,GPRS, etc.) For detailed selection list, please refer to Chapter 6
of this manual.
