1. Introduction
1.1 Overview
GCAN-PLC-510 programmable logic controller 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-510),1-32 arbitrary number of GC series terminal modules (GC-1008,
GC-3804, etc.) and a terminal module.
The GCAN-PLC-510 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-510 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-510
configuration/programming interface is a Micro-USB interface that can be used
to load PLC programs.
The GCAN-PLC-510 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.

2. Installation
This chapter introduces the method installation and wiring, the meaning of the
indicator and the interface.
2.1 Module appearance
GCAN-PLC-510 appearance as shown in Figure 2.1
GCAN-PLC-510 includes three communication interfaces, a controller
programming interface, a set of controller power interface, twosetsof I/O power
interfaces, two sets of Shielding line interfaces. Among them, the
communication interface includes one Ethernet interface, one CAN-Bus
interface and one RS232/RS485interface.
Figure 2.1 the appearance of GCAN-PLC-510
2.2 Fixed module
GCAN-PLC-510 and its matching terminal installation method is shown
in Figure 2.2

Figure 2.2 GCAN-PLC-510 programmable controller installation
Figure 2.3 GCAN-PLC-510 self-locking mechanism
As shown figure 2.2, install the GCAN-PLC-510 on the guide rail until the
lock is stuck. Then you need to rotate the orange knob on the left end of the
controller counterclockwise to fix the left end of the controller on the guide rail.
The GCAN-PLC-510 has a self-locking mechanism that can effectively prevent
equipment from falling.
As shown figure 2.3, you can release the self-locking mechanism by
pulling out the orange label and take out the controller or matching terminal
module. Before taking out the controller, you need to rotate the orange knob on
the left end of the controller clockwise to unlock it.

Guangcheng Technology GCAN-PLC user manual
The GCAN-PLC-510 can connect up to 32 distributed bus terminal
modules. When inserting the GC series terminal module, be sure to insert it
along the groove on the right side of the existing module sequentially until the
lock is stuck. 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.
Please note: When using the GCAN-PLC-510 controller, you must ensure that
you have installed terminal modul at the right end of the entire node, and the
terminal resistance module has been fixed to the bottom without looseness, as
shown in Figure 2.4. This terminal module will ensure the data transmission
and power supply between GC series IO modules. The lack of this terminal
module or improper installation will cause errors in the entire system.
Figure 2.4 GC-0001 Terminal resistance module installation method
2.3 Wiring method
The power wiring as shown in figure 2.4. First, use a flat-blade
screwdriver to insert into the square hole, hold the top edge of the metal sheet
in the square hole, and press toward the hole. Then, insert the wire into the hole.
After plugging in, pull out the screwdriver and the wire can be firmly locked in
the hole.

2.4 Interface definition
The main control module of GCAN-PLC-510 is composed of bus
communication module and power supply module. The bus communication
module integrates an Ethernet interface, an RS232/485 multiplex interface, and
a CAN bus interface, which are led out using RJ45 interface, RJ45 interface,
and 4P terminal interface respectively. The RS232 and RS485 interface styles
are shown in Figure 2.6, and the interface definitions are shown in Table 2.1;
the CAN bus interface style is shown in Figure 2.7.The interface definition is
shown in Table 2.2.
