GC-2018 module indicator
Note: When using, please connect digital output signal to the terminal of GC-
2018 and connect the reference ground to the negative power supply of GCAN-
PLC-400 or GCAN-IO-8000/8100 modules (corresponding to pins 5 and 6).
2.3 System statusindicator
The GC-2018 module has no error indicator. The user can determine the
status through the "IO RUN" and "IO ERR" indicators of the GCAN-PLC. If
the "IO ERR" indicator of the GCAN-PLC lights up, it indicates that the IO
module is not working properly. Please check the module installation.
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 digital output of GC-2018
module.
In the process of ST programming definition, gc-2018 module needs to
define variable type, output signal position, start character, delimiter and so on.
For example: "DI0 AT%I0.0:BOOL;"
"0.0"represents the position of the output point, and "0.0"~"0.7" respectively
define the 1-8 output points in the first GC-2018 module. When the user uses
more than one gc-2018 module, the second gc-2018 shall be defined from "1.0"
to "1.7", 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
