2. Installation
This chapter will describe the installation method, wiring method,
meaning of the indicator and meaning of the interface of the GC-1008 module.
2.1 Module fixing
The installation method of GC-1008 module as shown in Figure 2.1 and a
flat-blade screwdriver is needed for auxiliary installation.
Figure 2.1 Installation of GC-1008 module
First install the GCAN-PLC on the guide rail and plug the GC-1008 along
GCAN-PLC's right side until the lock is stuck. When remove the GC-1008, the
user need to release the self-locking mechanism by pulling out the orange label.
2.2 Wiring method
The power wiring as shown in figure 2.2. 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.

Note: When using, please connect digital input signal to the terminal of GC-
1008 and connect the reference ground to the negative power supply of GCAN-
PLC-400 or GCAN-IO-8000 modules (corresponding to pins 5 and 6).

Table 2.2
The GC-1008 module has no error indicator. The user can determine the
status through the "IO RUN" and "IO ERR" indicators of the GCAN-PLC. If
the "IO ERR" indicator of the GCAN-PLC lights up, it indicates that the IO
module is not working properly. Please check the module installation.
2.4 Combined with GCAN-PLC-400/510 series
When using with GCAN-PLC-400/510, GC series IO modules shall be
configured in the order of DI, DO, AI and AO, and the same type of modules
shall be put together.GCAN-PLC-400/510 supports programming in five
languages. The following is an example of ST language showing how to
program GCAN-PLC-400 to read the state of digital input of GC-1008 module.

Vhandy technology GC-1008 user manual
In the process of ST programming definition, gc-1008 module needs to define
variable type, input signal position, start character, delimiter and so on.
For example: "DI0 AT%I0.0:BOOL;"
"0.0"represents the position of the input point, and "0.0"~"0.7"
respectively define the 1-8 input points in the first GC-1008 module. When the
user uses more than one GC-1008 module, the second GC-1008 shall be
defined from "1.0" to "1.7", and so on.
"%" (percent sign) is the direct variable starter; ":" (colon) is the variable or
type separator.
The Boolean is read from the %I0.0 address using the symbol variable
DI0. AT represents the address of the variable access and the additional
attribute of the variable.
2.5 Combined with GCAN- 8000 series
The state of the digital input is represented by one byte, with channel 8 in
the high and channel 1 in the low.
For example,when GCAN-8000 module node number is 1,the input state
of channel 8 and channel 4 of the first GC-1008 module is logic "1", and the
input state of other channels is logic "0", the CAN data frame ID sent by the
GCAN-IO-8000 module is0x181,the data length(DLC) is 8, and the frame data
is 0x88, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00. Please note that when only
one GCAN-1008 module is inserted, only the first byte of the frame data is
valid. The table below lists two common DI state sand their corresponding
status data.
