2.3 System status indicator
The GC-4602 module has four running lights to indicate the operating status of
the device. The specific indication function of the indicator is shown in Table
2.2. When the LED is on, the status of the GC-4602 module 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-4602 module.
When the GC-4602 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, and each channel occupies 2 bytes, -
5V~+5V corresponds to -32768~+32767, so the second The starting address of
each channel is Q2.0. When the user uses more than one GC-4602 module, the
second GC-4602 needs to be defined from "Q4.0", because each 4602 has 2
channels; "%" (percent sign) means direct change write Signed shaping. AT
