1. Function Introduction
1.1 Function Overview
The GC-3864 module is an I/O module that integrates 4 input channels of
temperature sensors (T-type thermocouples). This module can be used to
collect temperature information in real time and send the collected values to
GCAN-PLC-400 or GCAN-8000/8100 series couplers through the internal bus.
This module can be used with any other GC series IO module to realize the
acquisition and processing of analog data in industrial automation or distributed
control systems.

2. Equipment installation and use
This chapter will explain in detail the installation method, wiring method, the
meaning of the indicator light and the meaning of the interface of the GC-3864
module.
2.1 Module fixing
The installation method of GC-3864 module is shown in Figure 2.1, you need
to use a flat screwdriver for auxiliary installation.
Figure 2.1 GC-3864 module installation
First, you need to install the fieldbus coupler on the rail, and then attach the
GC-3864 module to the right of the fieldbus coupler or other modules to add
this component. As shown in Figure 2.1, insert the GC-3864 module inward
along the slot until the latch snaps and makes a “click” sound.
The GC-3864 module needs to be used with a GCAN-PLC-400 or GCAN-
8000/8100 series coupler, and can be directly powered by the coupler, so there
is no need to separately provide additional power to it.
2.2 Wiring method
As shown in Figure 2.2, first use a flat-blade screwdriver to insert into the
square hole and hold the screw in the square hole. Then insert the cable into the
circular hole. After plugging in, pull out the screwdriver, and the cable can be
firmly locked in the circular hole.

Figure 2.3 GC-3864 module terminal block
The terminal block of GC-3864 module is shown in Figure 2.3. GC-3864
contains 4 sets of input points, and can connect up to 4 T-type thermocouples
sensors. The serial numbers corresponding to the terminals and their meanings
are shown in Table 2.1.

2.3 System status indicator
The GC-3864 module has 4 error indicators and 4 operation indicators 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 is on, the GC-
3864 module status is shown in Table 2.3.

2.4 Use in combination with GCAN-PLC-400/510 series
GCAN-PLC-400/510 supports programming in five languages. The following
uses ST language as an example to introduce how to use GCAN-PLC-400 to
program to read the status of the analog input of the GC-3864 module.
When GC-3864 module performs ST programming definition, it is necessary to
define the variable type, input signal position, start character, separator, etc. For
example: "AI0 AT%I0.0:INT;", where "0.0" represents the start address of the
Vhandy Technology GC-3864 user manual
first channel, each channel occupies 2 bytes, the collected temperature
corresponds to -32768~+32767 so the second The starting address of the
channel is I2.0.
When the user uses more than one GC-3864 module, the second GC-3864
needs to be defined from "I8.0", because each 3864 has 4 channels; "%"
(percent sign) is the direct variable start symbol : ":" (semicolon) is a variable
or type separator. Use the symbol variable AI0 to read the signed integer from
the %I0.0 address. AT stands for the address of variable access and the
additional attributes of the variable (see page 46 of the e-book for details).
(Note: Input only affects input, output only affects output, output and input do
not affect each other. That is, if there is and only output module in front of the
input module, then no matter how many output modules there are in front, the
address of the first input module is still I0 .0.)
2.5 Combination with GCAN-IO-8000 series equipment
The state of the analog input is represented by two bytes.
For example: the node number of GCAN-IO-8000 module is 1, the input state
of channel 1 of the first GC-3864 module is 250 ℃, and the input states of
other channels are not connected to the sensor, then the GCAN-IO-8000
module sends The CAN data frame ID is 0x181, the data length (DLC) is 8,
and the frame data is 0xC4, 0x09, 0xFF, 0x7F, 0xFF, 0x7F, 0xFF, 0x7F. The
following table lists a common AI state and its corresponding state data.
