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;"
