PLC Training: Data Tables FIFO and LIFO.UniLogic for UniStream by Unitronics

Introduction to UniLogic: The tutorial introduces UniLogic, an application development environment for the Unitronics UniStream control platform, presented by Alex. FIFO and LIFO Data Tables: The tutorial covers the concepts of FIFO (First-In-First-Out) and LIFO (Last-In-First-Out) data tables, explaining how they operate and their key functions, including push, pop, front, back, and clear. Data Table Memory: Data tables in UniLogic do not retain information by default after a power cycle. However, there is 256 kilobytes of memory available for retained space for both data tables and tags, which can be extended using a microSD card. FIFO vs. LIFO: FIFO writes new information to the back of the data table and removes data from the front, while LIFO writes to the front and removes data from the back. The tutorial explains the difference between these two systems and their behavior. Programming Example: The tutorial provides an example program for both FIFO and LIFO data tables, demonstrating how to set up and use these tables, create structs, and perform functions like push, pop, and clear. It also shows how to display data on an HMI (Human-Machine Interface).
