2. Installation
This chapter will describe the installation method, wiring method, meaning of
the indicator and meaning of the interface of the GC-2008 module.
2.1 Module fixing
The installation method of GC-2008 module as shown in Figure 2.1 and a flat-
blade screwdriver is needed for auxiliary installation.
Figure 2.1 Installation of GC-2008 module
First install the GCAN-PLC on the guide rail and plug the GC-2008 along
GCAN-PLC's right side until the lock is stuck. When remove the GC-2008, 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.

Table 2.1 GC-2008 module indicator
Note: When using, please connect digital output signal to the terminal of GC-2008
and connect the reference ground to the negative power supply of GCAN-PLC-400 or
GCAN-IO-8000/8100 modules (corresponding to pins 5 and 6).

Table 2.2
The GC-2008 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-400/510series
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 output of GC-2008 module.
In the process of ST programming definition, gc-2008 module needs to define
variable type, output signal position, start character, delimiter and so on.

Vhandy technology GCAN-2008 user manual
For example: "DI0 AT%I0.0:BOOL;"
"0.0"represents the position of the output point,and"0.0"~"0.7"respectivelydefinethe
1-8 output points in the first GC-2008 module. When the user uses more thanone
gc-2008 module, the second gc-2008 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- 8000series
The state of the digital output 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 output state of
channel 8 and channel 4 of the first GC-2008 module is logic "1", and the output state
of other channels is logic "0", the CAN data frame ID sent by the GCAN-IO-8000
module is 0x181,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-2008 module is
inserted, only the first byte of the frame data is valid. The table below lists two
common DI states and their corresponding status data.
