1. Function introduction
1.1 Functional Overview
The GC-6501 module is an extended communication module that integrates 1
channel Wifi. This module can be used to expand Wifi communication, and can
be connected to AP nodes, collect data through TCP and UDP communication,
and send the collected values to the GCAN-PLC-510 series PLC controller
through the internal bus, and at the same time expand the serial port function
by calling Block programming to achieve complex bus control requirements.
This module can be used in conjunction with any other GC series IO module to
realize the receiving and sending of data in industrial automation or distributed
control systems.
1.2 Performance characteristics
●The form of extended Wifi is Station;
●Support TCP Client and UDP communication form;
●Ethernet parameters are set by function blocks in the program;
●Electrical isolation is 500Vrms;
●Power supply through GCAN-PLC-510 and external 24V-DC power supply;
●Current consumption is200mA;
●Configuration without address setting, configuration through bus coupler or
controller;
●Operating temperature range:-40
℃
~+85
℃
;
●Dimensions: length 100mm * width 69mm * height12mm.
1.3 Typical application
●Add Wifi extension function to PLC controller;
●The bus data can be sent and received by calling the extended Wifi function
block in the program.

2. Equipment installation and use
This chapter will explain in detail the installation method, wiring method,
meaning of indicator lights and interface meaning of GC-6501 module.
2.1 Module fixed
The installation method of GC-6501 module is shown in Figure 2.1, you need
to use a flat-blade screwdriver to assist installation.
Figure 2.1 GC-6501 Module installation
First, you need to install the fieldbus coupler on the rail, and then attach the
GC-6501 module to the right side of the fieldbus coupler or other modules to
add this component. Please insert the GC-6501 module inward along the slot as
shown in Figure 2.1 until the lock catches and makes a "click" sound.
GC-6501 module needs to be used with GCAN-PLC-510 coupler
。
2.2 Wiring method
As shown in Figure 2.2, first insert a flat-blade screwdriver into the square hole
and hold the screw in the square hole. Then insert the cable into the circular
hole. After plugging it in, pull out the screwdriver and the cable can be firmly
locked in the circular hole.

2.3 System statusindicator
The GC-6501 module has 4 indicator lights to indicate the operating status of
the device. The specific indication function of the indicator light is shown in
Table 2.2. When the indicator light is on, the GC-6501 module status is shown
in Table 2.3.
