2.3 System statusindicator
The GC-4622 module has 4 operating indicators 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-4622 module status is shown in
Table 2.3.

2.4 Use in combination with PLC400/510 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 and write the status of the analog output of the GC-4622 module.
When the GC-4622 module performs ST programming definition, it is
necessary to define the variable type, output signal position, start character,
separator, etc. For example: "AO AT%Q0.0:INT;", where "0.0" represents the
starting address of the first channel, each channel occupies 2 bytes, -10V~+10V
corresponds to -32768~+32767, so the second The starting address of each
channel is Q2.0. When the user uses more than one GC-4622 module, the
secondGC-4622 needs to be defined from "Q4.0", because each 4622 has 2
channels; "%" (percent sign) is the direct variable start character: ":"
(semicolon) is the variable or type separator. Use the symbol variable AO to
