WAGO 750-616 PROFIBUS DP Coupler | 32-Channel, 12Mbps, DIN Rail, Modular I/O

WAGO 750-616 PROFIBUS DP Coupler | 32-Channel, 12Mbps, DIN Rail, Modular I/O

WAGO 750-616 PROFIBUS DP fieldbus coupler specifications. 12Mbps, 32-channel capacity, modular I/O, 24V DC. Connects WAGO-I/O-SYSTEM to PROFIBUS DP networks.

Product Overview

The WAGO 750-616​ is a fieldbus coupler​ for the WAGO-I/O-SYSTEM, designed to connect WAGO's modular electronic terminal blocks (I/O modules)​ to a PROFIBUS DP network. It acts as the intelligent network interface and controller​ for a local I/O station. Supporting PROFIBUS DP-V1​ with data rates up to 12 Mbps, it can manage a 32-channel (module) local bus​ and provides the power and communication interface​ for connected digital, analog, and special function modules. It is a core component for building distributed I/O nodes on a PROFIBUS DP network.

Technical Specifications

Note: Specifications are based on the WAGO-I/O-SYSTEM 750 datasheet. Always verify with the latest documentation.

Key Features

• PROFIBUS DP-V1 Interface:​ Connects modular I/O to a PROFIBUS DP master (e.g., Siemens PLC)

• High Channel Density:​ Controls up to 32 I/O modules (digital, analog, special) on the local bus

• 12 Mbps Communication:​ Supports the maximum PROFIBUS DP data rate

• Modular and Flexible:​ I/O configuration can be customized for any application

• Easy Addressing:​ Rotary and DIP switches for setting the PROFIBUS DP station address (0-125)

• Integrated Diagnostics:​ LEDs and diagnostic data for quick troubleshooting

• Auto Baud Detection:​ Automatically detects the network baud rate

• Standard GSD File:​ Easy integration into Siemens STEP 7, TIA Portal, or other PLC engineering tools

• Powerful Local Bus:​ Supplies 5V/2A for module electronics and manages 24V field power distribution

• WAGO CAGE CLAMP®:​ Tool-free, maintenance-free connection technology

Installation Steps

1. Mounting:​ Mount the coupler on a 35mm DIN rail.

2. Addressing:​ Set the unique PROFIBUS DP address (0-125) using the rotary and DIP switches.

3. Wiring:​ Connect the 24V DC supply to terminals X4 (24V, 0V). Connect the PROFIBUS DP network cable to terminals X1 (In) and X2 (Out). Connect the functional ground (X3).

4. Power Feed Module:​ Insert the required 24V power feed module (e.g., 750-600) directly to the right of the coupler.

5. I/O Modules:​ Insert and configure the required digital, analog, and special function modules.

6. Configuration:​ Use the GSD file in the PLC configuration tool (e.g., Siemens STEP 7) to configure the station's I/O layout.

7. Commissioning:​ Apply power, verify LED status, and start data exchange with the master.

Software and Configuration

• GSD File:​ WAGO0B06.GSD(specific file version required, available from WAGO website).

• Configuration Tools:​ Configure within the PLC engineering software (e.g., Siemens TIA Portal, STEP 7) or using WAGO-I/O-CHECK for stand-alone configuration.

• Process Image:​ Define the input and output data areas in the PLC configuration.

Typical Applications

• Distributed I/O Stations:​ Replacing hardwired signals with a PROFIBUS DP network

• Machine Control:​ Modular I/O for packaging, assembly, and material handling machines

• Process Skids:​ Pre-fabricated control systems for process industries

• Building Automation:​ HVAC, lighting, and access control

• Retrofit Projects:​ Upgrading existing panels to networked I/O

• Any application​ requiring a flexible, modular remote I/O station on PROFIBUS DP

Important Technical Notes

1. Power Supply:​ The 24V DC supply on X4 powers the coupler's electronics only. A separate 750-600 series power feed module is mandatory​ to provide 24V power to the connected I/O modules and field devices.

2. Address Conflicts:​ Ensure each 750-616 on the network has a unique address between 0 and 125.

3. Bus Termination:​ The first and last node on the PROFIBUS DP segment must have termination enabled. The 750-616 has a termination resistor switch for this purpose.

4. Module Limit:​ The 32-module limit refers to physical modules, not channels. Complex modules (e.g., 8-channel analog input) count as one module.

5. Configuration:​ The I/O layout configured in the PLC must match the physical module order on the local bus.

6. GSD File:​ Always use the latest GSD file from the WAGO website for full functionality and compatibility.

7. Grounding:​ Always connect the functional ground (FG, terminal X3) to the cabinet ground for optimal noise immunity.
