2. Installation and use
This chapter will describe the installation method, wiring method, meaning
of the indicator and meaning of the interface of the GC-2204 module.
2.1 Module fixing
The installation method of GC-2204 module as shown in Figure 2.1 and a
flat-blade screwdriver is needed for auxiliary installation.
Figure 2.1 Installation of GC-2204 module
First the user need to install the GCAN-PLC on the guide rail and plug the
GC-2204 along GCAN-PLC's right side until the lock is stuck. When remove
the GC-2204, the user need to release the self-locking mechanism by pulling
out the orange label.
Note: The GC-2204 module needs to be used with GCAN-PLC-400/510 or
GCAN-8000/8100 series couplers, and can be powered directly through the
coupler, so there is no need for a separate additional power supply.
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.

2.3 System status indicator
The GC-2204 module is equipped with 4 running indicator lights, which
are used to indicate the running state of the equipment.The specific indication
function of the indicator light is shown in Table 2.2. When the indicator light is
on, the status of the GC-2204 module is shown in Table 2.3

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 relay output of GC-2204 module.
In the process of ST programming definition, gc-2204 module needs to define
variable type, output signal position, start character, delimiter and so on.
For example: "DI0 AT%I0.0:BOOL;"
8
Guangcheng Technology GC-2204 user manual
"0.0" represents the position of the output point, and "0.0"~"0.3" respectively
define the 1-4 output points in the first GC-2204 module. When the user uses
more thanone
gc-2204 module, the second gc-2204 shall be defined from "1.0" to "1.3", 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 a byte, channel 4 in the
high and channel 1 in the low.
For example, if the node number of the gcan-io-8000 module is 1, 4
channels of the first GC-2204 module should be set The output state of channel
is logical "1", and the output state of other channels is logical "0", which needs
to pass through the master stationGcan-io-8000 sends data, its frame ID is
0x201, the data length (DLC) is 1, and the frame data is0x08 note that if only
one gc-2204 module is used, only the first byte in the frame data is effective.
The following tables 2.4 and 2.5 list two common DO states and their
corresponding status data.
