Hi everyone.
My question about: where I can learn (read or watch) an info about codesys workflow through the system IO libs? I want to know how to implement I/O drivers by my self.
In the system libs I see many interfaces, methods etc... But there is no explanation about them, just names of methods and fields of the FBs.
I know about this page: https://forge.codesys.com/drv/io-drivers/doc/Generic/
There is so BIG the device description file and not so clear explaining of the attributes and elements, also some elements or attributes missed at it all. Yes, there are code examples on this page, but, so shortly and, for example, code about Modbus drivers is absent. And even if I try to add the IoDrvFB with lib, I get and error, something like: "failed to load IoDrvFB driver".
And what about the book of codesys that written by Gary Pratt? Is there information about system libs and drivers in this book more clearly?
Thank you :)
