1. Introduction

The WAGO 750-501 Digital Output Example is a minimal demonstration showing how to set the digital outputs on a WAGO 750-501 EtherCAT terminal using the QiTech machine framework. It represents one of the simplest possible hardware interactions in the system: Controlling 2 Digital Outputs using the QiTech Control Dashboard. Each output state is also reflected by the built-in LED on the terminal — no additional wiring is required to observe the output.

2. Requirements

Hardware

• WAGO 2787-2144 EtherCAT
• WAGO 750-354 EtherCAT Coupler
• WAGO 750-602 EtherCAT Power Terminal
• WAGO 750-501 EtherCAT Terminal (2-Channel Digital Output)
• WAGO 750-600 EtherCAT Endmodule
• WAGO 852-1322 Ethernet-Switch
• 24V DC Lab power supply (AC/DC adapter)
• A Linux PC (Ubuntu/Debian recommended)
• Standard Ethernet cable

Software

See Device Example Basics for software prerequisites.

3. Hardware Setup

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

3.2 Wiring Steps (Used in This Example)

We supply power to the other devices by using the 750-602 EtherCAT Power Terminal

Perform the following wiring on the Ethernet-Switch:

1. Red wire (+24V) → PWR+
2. Black wire (0V) → RPS-

3.3 WAGO Wiring the Coupler

Wire the 750-354 EtherCAT Coupler to the power supply:

1. Red wire (+24V)
2. Yellow wire (0V)

3.4 750-602 EtherCAT Power Terminal Integration

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

Perform the following wiring steps:

1. Green wire (Ground) → Terminal 4
2. Red wire (+24V) from 750-602 EtherCAT Power Terminal → Terminal 2
3. Black wire (0V) from 750-602 EtherCAT Power Terminal → Terminal 3
4. Red wire (+24V) from 750-354 EtherCAT Coupler → Terminal 6
5. Yellow wire (0V) from 750-354 EtherCAT Coupler → Terminal 7

3.5 750-501 EtherCAT Terminal Integration

Slide the 750-501 EtherCAT Terminal onto the right side of the 750-602 EtherCAT Power Terminal until it locks.

The terminal receives its power through the pin connectors — no additional wiring is required. The output state of each channel is visible via the built-in LED on the terminal face.

3.6 750-600 Final Assembly

Slide the 750-600 EtherCAT Endmodule onto the right side of the 750-501 EtherCAT Terminal until it locks.

No further wiring is required.

3.7 Power & Ethernet

Power

Connect the 2787-2144 power supply to the power outlet.

Ethernet

Use a standard LAN cable to connect your PC → 852-1322 Ethernet-Switch

And another from 852-1322 Ethernet-Switch → 750-354 EtherCAT Coupler

4. Software Setup

See Device Example Basics to install and run the software, then return here for the device-specific demo steps.

5.1 Assigning Devices in the Dashboard

Once the backend + frontend are running, you should see:

• WAGO750-354 (Coupler)

• WAGO750-501 (2CH DO)

Steps:

• Click Assign on the 750-354 module

• Select "Wago 750-501 DO Test V1"

• Enter a serial number other than 0

• Keep the device role unchanged if it is set to "Wago 750-354 Bus Coupler"

• Repeat these steps for the 750-501 module using the same non-zero serial number

• Finally, restart the Backend process

5.2 Controlling the Outputs

In the left sidebar, Wago 750-501 DO Test should appear. Click it.

You will see two output channels — Do1 and Do2 — each with an On/Off toggle.

Toggling an output to On activates the corresponding channel and lights up the LED on the 750-501 terminal face. Toggling it to Off deactivates the channel and turns the LED off.

A Master Output Control panel is also available to turn all outputs on or off simultaneously.
