i!-PCLinkWeb
Levels
i!-PCLink/Web supports the following control levels (master to PC).
Module
You can program the i!-PCLink/Web application directly using the commands and strings or you
can use the supplied module and accept the functionality it offers. Both methods have their place so
using one or the other depends or your situation. For instance, if you are building a kiosk
application then sending strings of the files or URL's you need to open may be all that is required.
In this instance, there is no need to have file navigation from the touch panel so the module is of
little use.
You can use a combination of the module and your own programming if you prefer. To assist you in
your own programming, the module code is supplied as open source. You can use this is a start to
create custom programming or use it as-is for the standard functionality.
To include the module in your program, you must first compile the supplied module code. This will
create the "i!-PCLinkWeb2Mod.tko". Then, define an instance of the module in your program using
a DEFINE_MODULE line like the example below (normally, DEFINE_MODULE statements are
listed following the DEFINE_START section):
DEFINE_MODULE 'i!-PCLinkWeb2Mod' mdlWEB(dvPCLinkWeb,
dvTP,
dvKB)
Where: mdlWEB is a unique module name
dvPCLinkWeb is the device number of the i!-PCLink/Web application as setup in the
device section of the control panel.
dvTP is the touch panel device array that i!-PCLink/Web application will communicate
with.
