1. Introduction

Modern industrial PLC systems use distributed fieldbus I/O modules such as the WAGO 750-530 to interface with real-world signals. These modules extend the controller by providing physical input and output channels.

I/O modules exist in various types, including:

• Analog inputs
• Analog outputs
• Digital inputs
• Digital outputs

From a programming perspective, each channel corresponds to a mapped variable inside the control system.

The WAGO 750-530 provides eight digital output channels, each represented as a boolean value (true / false). These outputs can be used to:

• Switch relays
• Control indicator lights
• Drive contactors
• Activate external devices

This example demonstrates the simplest possible interaction: toggling the output values on and off using the QiTech Control frontend and observing the corresponding physical signal changes on the module.

3. Hardware Setup

---

3.1 Schematic

---

⚠️ Always disconnect power before wiring. See Device Example Basics for the safe wiring procedure.

---

3.3 Power Supply

The 750-602 EtherCAT Power Terminal requires 24V DC.
In this example, a standard 24V AC/DC adapter with a hollow plug is used.

Perform the following wiring on the 750-530:

1. Hollow plug red wire (+24 V) → Terminal 6
2. Hollow plug black wire (0 V) → Terminal 7

---

3.4 Coupler Integration

Slide the 750-602 EtherCAT Power Terminal onto the right side of the 750-354 Coupler until it locks.

Perform the following wiring:

1. Red wire Terminal 2 of 750-602 → Supply voltage port (+24 V) of the 750-354
2. Black wire Terminal 3 of 750-602 → Supply voltage port (0 V) of the 750-354

---

3.5 Digital Output Module Integration

Slide the 750-530 EtherCAT Terminal onto the right side of the 750-602 until it locks.

---

3.6 End Module Integration

Slide the 750-600 End Module onto the right side of the 750-530 until it locks.

---

3.7 Power

Connect the 24V AC/DC adapter to the hollow plug installed earlier.

3.8 Ethernet

Connect your PC to the INPUT port of the 750-354 Coupler.

5.1 Assigning Devices

After backend and frontend are running, open the EtherCAT tab.

You should see:

• WAGO 750-354 (Coupler)
• WAGO 750-530 (Digital Output Terminal)

For both devices:

1. Click Assign
2. Select Wago DO Test V1
3. Enter a serial number
   • Must not be 0
   • Must be the same for both devices
4. Click Write

---

Restart the backend.

In the vertical navigation bar, Wago DO Test should now appear. Click on it:

---

You can now toggle the eight outputs of the 750-530:
