Live Siemens PLC Tutorials: DataBlocks (DB), Data Types, Arrays, and Indirect Addressing (POINTERS)
Lets get back on track going into the new year. If you work with Siemens PLCs you will not want to miss this stream! We will be talking about MEMORY!!! WAHOO! I know you are excited! Seriously though, a good understanding of how memory is organized and used in TIA Portal (and SIMATIC Manager) will make your life so much easier. JOIN LIVE to take part in the conversation!
This stream we will walk from the a basic level through intermediate topics and finish up by discussing some of the most advanced and difficult topics out there. We ALL will learn something from this stream! Below is what we will cover:
DB Basics: What is a data block and why are they a big deal?
Data Types: Basics, UDTs
How to use UDT (PLC Datatypes) to organize and access data (Example with SINA_PARA)
Arrays and Array Index: How to use arrays in portable code.
Pointers: Unlocking Unlimited Potential (for JOY and PAIN).
SCL Basics: How to start using SCL in TIA Portal.
