 # QiTech Control

-QiTech Control is an open-source framework designed to bring modern software paradigms to certified industrial hardware.
-
-It frees developers from proprietary, license-heavy PLC ecosystems and rigid "point-and-click" workflows that are no longer adequate for today's complex automation challenges.
-
-QiTech Control combines the modularity and reliability of standard EtherCAT terminals (e.g., WAGO, Beckhoff) with the power of a modern Rust & React stack.
-
+QiTech Control is an industrial control panel software for the next generation of QiTech recycling machines built on top of Beckhoff Automation hardware.

-To interface with Beckhoff and other EtherCAT devices we need an EtherCAT master software.

For realtime operation only C and Rust are suitable. We chose Rust because of safety and confidence in the written code.

-> Backend
 - Rust stable 1.86^ toolchain (install via [rustup](https://rustup.rs/))
 - `rust-analyzer` extension for VSCode
 - Set your interface in `server/src/ethercat/init.rs` like `en10`
 - Connect a Beckhoff EK1100 to your interface
 - run `cd server && cargo run` to start the server (localhost:3001)

-> Frontend

 - nodejs and npm installed
 - run `cd electron && npm i && npm run start` to start the frontend

-# XTREM Communication Protocol
-
-**Version:** 3.007
-**Device:** XTREM / XTREM-S Weighing Module
-**Standard:** OIML R76:2006 / EN45501:2015 compliant
-
---
-
-## Overview
-
-The **XTREM communication protocol** allows a terminal or host controller to exchange data and commands with the XTREM weighing module.
-The device transmits and receives ASCII-coded frames over a serial interface (RS232, RS485, Wi-Fi, or Ethernet, depending on configuration).
-
-Since we are using the Ethernet interface we need to provide some kind of DHCP to assign an IP - Address to each XTREM Device.
-They then may be addressed via a **broadcast** IP (e.g.: 192.168.4.255/24).
-A **Unicast** communication is applied through the device ID inside the XTREM Frame.
-
---
-
-## Frame Structure
-
-Each message—both query and response—has the same format:
-
-```
-STX ID_O ID_D F D_ADDRESS D_L DATA LRC ETX
-```
-
-| Field         | Description                                       | Length (bytes) |
-| :------------ | :------------------------------------------------ | :------------: |
-| **STX**       | Start of message (ASCII `02h`)                    |        1       |
-| **ID_O**      | Sender address (2 ASCII hex chars)                |        2       |
-| **ID_D**      | Destination address (2 ASCII hex chars)           |        2       |
-| **F**         | Function code (`R`, `W`, `E`, etc.)               |        1       |
-| **D_ADDRESS** | Data address (register, 4 ASCII hex chars)        |        4       |
-| **D_L**       | Data length (2 ASCII hex chars)                   |        2       |
-| **DATA**      | Optional data field                               |    Variable    |
-| **LRC**       | Longitudinal Redundancy Check (2 ASCII hex chars) |        2       |
-| **ETX**       | End of message (ASCII `03h`)                      |        1       |
-
-In the default configuration the Frame also requires a CRLF at the end.
-
-**Example:**
-
-```
-STX ‘1’ ‘7’ ‘0’ ‘1’ ‘R’ ‘0’ ‘1’ ‘0’ ‘1’ ‘0’ ‘0’ LRC ETX CR LF
-```
-
---
-
-## Function Codes
-
-| Function | ASCII | Hex | Description     |
-| :------- | :---- | :---| :-------------- |
-| **R**    | R     | 52h | Read request    |
-| **r**    | r     | 72h | Read response   |
-| **W**    | W     | 57h | Write request   |
-| **w**    | w     | 77h | Write response  |
-| **E**    | E     | 45h | Execute command |
-| **e**    | e     | 65h | Execute response|
-
-### Write response codes
-
-* `'0'` – OK
-* `'1'` – Write denied (sealed)
-* `'2'` – Read-only register
-* `'3'` – Invalid value / out of range
-
-### Execute response codes
-
-* `'0'` – Executed successfully
-* `'1'` – Blocked by seal switch
-
---
-
-## LRC Calculation
-
-The **Longitudinal Redundancy Check** is a one-byte XOR of all message bytes, excluding:
-
-* `STX`
-* `ETX`
-* The LRC itself
-
-Example C function:
-
-```c
-unsigned char LRC(unsigned char* s) {
-    unsigned char lrc = 0;
-    while (*s) {
-        lrc ^= *(s++);
-    }
-    return lrc;
-}
-```
-
-Example Rust function:
-```rust
-pub fn compute_lrc(data: &[u8]) -> u8 {
-    data.iter().fold(0u8, |acc, &b| acc ^ b)
-}
-
-```
-
---
-
-## Key Data Registers
-
-| Address (hex) | Description                | Type | Notes                                 |

-## Post-Factory Reset Configuration
-
-After performing a factory reset, several registers must be configured to ensure proper operation of the device.
-
-Note: The unit may remain set to 'g' after a factory reset, but the values received may be in 'kg' depending on the device configuration.
-
-The following registers should be reviewed and set as required:
-1. **Address: 0022 | Max (Max1) (scale maximum capacity)**
-    The default value for this register may vary between devices (e.g., 60000 or 6000). Set this value to 6000 to ensure correct operation.
-2. **Address: 0023 | e (e1) (scale interval)**
-3. **Address: 0026 | Decimal position**

-## 1. Introduction
-
-The EL2004 LED Toggle Example is a minimal demonstration showing how to control digital outputs on a **Beckhoff EL2004 EtherCAT terminal** using the QiTech machine framework.  
-It represents the simplest possible hardware interaction in the system:  
-**toggling LED outputs using the QiTech Control Dashboard.**
-
---
-
-## 2. Requirements
-
-### Hardware
- Beckhoff **EL2004 EtherCAT Terminal** (4-channel digital output)  
- Beckhoff **EK1100 EtherCAT Coupler**  
- **24 V DC power supply** (AC/DC adapter + DC hollow plug)  
- Jumper / bridge wires (0.5–1.5 mm² recommended)  
- A **Linux PC** (Ubuntu/Debian recommended)  
- Standard Ethernet cable  
- Flat screwdriver  
-
-### Software  
-*(Installation steps in Section 4)*  
- Rust toolchain  
- Node.js + npm  
- Git  
- QiTech Control repository  
- EtherCAT HAL (included inside repo)
-
---
-
-## 3. Hardware Setup
-
-### 3.1 Schematic
-
-![](../assets/schematic.png)
-
---
-
-### 3.2 EK1100 Wiring
-
-This wiring configuration powers the EL2004 and prepares it for LED control.  
-It is not the only possible wiring but is the **simplest functional setup**.
-
-#### ⚠️ Safety Warning  
-Always disconnect power before wiring.  
-Working on live EtherCAT terminals can cause serious damage or electrical shock.
-
---
-
-#### 3.2.1 Safe Wiring Procedure (Beckhoff Recommended)
-
-1. Insert a screwdriver **straight** into the square release hole.  
-2. Insert the stripped wire into the round opening.  
-3. Remove the screwdriver — the spring clamp locks the wire.
-
-![](../assets/wiring.png)
-
---
-
-#### 3.2.2 Wiring Steps (Used in This Example)
-
-We supply power using a **DC hollow-plug adapter**, like this one:  
-https://www.amazon.de/dp/B093FTFZ8Q
-
-Perform the following wiring on the EK1100:
-
-1. Red wire **(+24 V)** → Terminal **2**  
-2. Black wire **(0 V)** → Terminal **3**  
-3. Jumper wire from **Terminal 1 → Terminal 6**  
-4. Jumper wire from **Terminal 5 → Terminal 7**  
-
-After wiring, your module should look like **Figure 1**.
-

-
-
---
-
-### 3.3 EL2004 Integration
-
-Slide the EL2004 onto the **right side of the EK1100** until it locks.  
-The EtherCAT E-Bus and power contacts connect automatically — **no wiring required**.
-
-#### **Figure 2 — EL2004 Terminal**

-
-### 3.4 Final Assembled Setup
-
-#### **Figure 3 — EK1100 + EL2004 Connected**
-<img src="../assets/complete.jpeg" width="400">
-
---
-
-### 3.5 Power & Ethernet
-
-#### Power  
-Connect the 24 V adapter to the hollow plug used earlier.
-**Example AC/DC Adapter (Figure 4):**
-
-<img src="../assets/adapter.jpeg" width="400">
-
-
-#### Ethernet  
-Use a standard LAN cable to connect your PC → EK1100.
-The final powered up and connected setup should look like this:

-
-## 4. Software Setup
-
-### 4.1 Installing on Ubuntu/Debian
-
-Paste this into your terminal:
-
-```bash
-# Press Enter when prompted
-curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
-
-sudo apt update
-sudo apt install -y npm nodejs git
-
-git clone git@github.com:qitechgmbh/control.git
-cd control/electron
-npm install
-```
-### 4.2 Running the Backend
-```bash
-./cargo_run_linux.sh
-```
-This script:
-
- Builds the backend
-
- Grants required system capabilities (raw sockets)
-
- Starts EtherCAT communication
-
-Ensure the EK1100 is connected.
-
-### 4.3 Running the Frontend
-```bash
-cd electron
-npm run start
-```
-This launches the QiTech Control dashboard.
-
-## 5. Demo
-
-### 5.1 Assigning Devices in the Dashboard
-
-Once the backend + frontend are running, you should see:
-
- EK1100 Coupler
-
- EL2004 Digital Output Terminal
-![](../assets/discovery.png)
-
-Steps:
-
- Click Assign on the EK1100
-
- Select TestMachine V1
- 
-![](../assets/setmachine.png)
