1. Preliminary Report: PLC Trainer
The main idea of our project is to fix the functionality for Waltech so it runs more like RSLogix500

2. Programmable Logic Controller (PLC)
Abstract
Programmable Logic Controllers are widely adopted in Industrial Automation
RSLogix 500 is the application used to program the PLC
Programmable Logic Controller (PLC)

3. Problem PLC: $500 - $4000 Arduino Nano/Mega/Uno: $20 - $50
Electronic Bread Board: $10
Arduino Nano
Arduino Uno
Arduino Mega

4. Problem (Cont.)
Industrial Automation’s biggest challenge today is the high initial cost to purchase or program automated machinery
The GUI application allows the mechanical engineers to program these complicated devices without actually understanding the underlying code
This open source application will allow students to work outside of the lab on the hardware of their choice

5. Timers and Counters Timer On Delay Retentive Timer On Counter up
Counter down

6. Three Overarching Tasks
Filling out the rest of the instruction set, including timer and counter functionality
More efficient and convenient management of input and output assignments
Live feedback of Arduino state through serial communication

Elements and instruction that define the ladder logic
List of elements in current program design
Console for debugging purposes
GraphicsScene where user can design unique ladder logic programs for testing
Console for user-directed messages
Tools for manipulating rungs and ladder

11. Ladder Logic to Arduino
Outline To C
Hex maker
AVR
The ladder logic is converted to C code here, python uses a string to create C code. Our added functionality has been integrated here.
C code is compiled with AVR-GCC, converted into hex, and flashed into Arduino

12. Send Command to get I/O states
Serial Communicator
Send Command to get I/O states
Check Register for command
Go through all input and output registers generating a string of 0’s and 1’s
