2.4 Use in combination with GCAN-PLC-400/510 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 to read the status of the analog input of the GC-3822 module.
When the GC-3822 module performs ST programming definition, it is
necessary to define the variable type, input signal position, start character,
separator, etc. For example: "AI0 AT%I0.0:INT;", where "0.0" represents the
