1. Function introduction
1.1 Functional Overview
The GC-3822 module is an I/O module with integrated 2 temperature sensor
(PT100) input channels. The module can be used to collect temperature
information in real time and send the collected values to the GCAN-PLC-
400/510 series controller or GCAN-8000/8100 series coupler via the internal
bus. This module can be used with any other GC series IO module to realize
the collection and processing of temperature 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 indicator light and the meaning of interface of GC-3822 module.
2.1 Module fixing
The installation method of the GC-3822 module is shown in Figure 2.1. You
need to use a flat-blade screwdriver for auxiliary installation.
Figure 2.1 GC-3822 module installation
First, you need to install the fieldbus coupler on the rail, and then attach the
GC-3822 module to the right of the fieldbus coupler or other modules to add
this component. As shown in Figure 2.1, insert the GC-3822 module inwards
along the slot until the latch snaps and makes a “click” sound.
The GC-3822 module needs to be used with the GCAN-PLC-400/510 series
controller or the GCAN-8000/8100 series coupler, and can be directly powered
by the coupler, so there is no need to separately provide additional power toit.
2.2 Wiring method
As shown in Figure 2.2, first use a flat-blade screwdriver to insert into the
square hole and press 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-3822 module terminal block
The terminal block of GC-3822 module is shown in Figure 2.3. The GC-3822
contains 2 sets of inputs and can connect up to 2 PT100 sensors. The serial
numbers corresponding to the terminals and their meanings are shown in
Table2.1.

2.3 System statusindicator
The GC-3822 module has 2 red error indicators 2 and 4 and 2 green operation
indicators 1 and 3 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-3822 module status is shown in Table2.3.

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-3822 module.
When the GC-3822 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
Vhandy Technology GC-3822 user manual
start address of the 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-3822
module, the second GC-3822 needs to be defined from "I4.0", because each
3822 has 2 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: GCAN-IO-8000 module node number is 1, the input status of
channel 1 of the first GC-3822 module is 26 ℃, and the input status of other
channels is not connected to the sensor, then the GCAN-IO-8000 module sends
CAN data frame ID is 0x181, data length (DLC is 8, frame data is 0x04, 0x01,
0xFF, 0x7F, 0xFF, 0x7F, 0xFF, 0x7F
