Dear existing & future PLC software developers, I have published part 9 of my free PLC programming using TwinCAT 3 tutorial.
In this part we’ll learn how to use one of the most used Beckhoff libraries for various purposes. We’ll learn how to measure execution time of PLC code, how to use a FIFO buffer and how to combine the power of using a TwinCAT real-time program with an application running in user-space (Windows).
PLC programming using TwinCAT 3 tutorial – part 9
Thank’s a lot.
I work many years with Twincat…and never know about a ring buffer FB in Beckhoff library
(every time a need i make it by myself)
your tutorials are amazing!
I can feel youy passion for this issues
Hi Max! Thanks for the kind words. Yes I still discover new stuff in the utilities library. It’s just a box full of candy!
Hi Jakob
I am a engineer in Taiwan , Your webside & video is really great,I fullly agree with your thoughts
I like to share one ideaI I used to try. Use NT_Startprocess to start progeam & redirection output to get result
eg ping , you can ues “where ping” in command prompt to get program path.
use “>” redirection to anouther file for TwinCAT PLC get the result，But I got problem on I can’t pass redirection via NT_Startprocess , eventually i use batch file instead，but It’s not work on WinCE@@
I still trying on it,Just sharing my experience hope it’s help.
It was good to know about Memring buffer … But I have a question regarding buffer.I am new to beckhoff world
How can we add different Hex data of different data length into one buffer OF byte array
For example
G:UINT:= 16#0001// STRUCTURE ST
F:USINT:=16# 0002// STRUCTURE ST
B:UINT : 16 #0003// STRUCTURE BT
G and F are same structure ST and B is of different structure BT
how to add this into byte array buffer
For example byte array should look like this : 00 01 02 00 03
