Quick Start Guides
Our quick start guides are here to help you get your HMI and PLC talking to each other as quickly and painlessly as possible. Click on the button below to show more details for the protocol you are using, and learn how to connect your devices in a few easy steps.
EtherNet/IP-DF1
This guide walks you through connecting an Allen-Bradley CompactLogix or ControlLogix PLC to EBPro using EtherNet/IP, importing controller tags, and using those tags in your HMI project. Follow these steps to establish communication and begin building your screens with confidence.
Instructions: EtherNet/IP-DF1
Connect the PLC and Your PC Using Ethernet
Using a standard Ethernet cable, connect the Allen-Bradley PLC to a PC that is running EBPro. Make sure the PC and PLC’s IP addresses are on the same subnet, otherwise they will not be able to communicate directly.
Start a New Project and Add the Allen-Bradley EtherNet/IP Device
Start a new EBPro project. Add a new Device/Server and select Allen-Bradley Compact/ControlLogix Free Tags (EtherNetIP-CIP Preferred) as the driver to use.
Enter the PLC IP Address
Open the Settings menu for the Allen-Bradley device, and enter the IP address for your PLC.
Import Tags from the PLC
Save the settings in the Device Properties window and click Import Tags in the System Parameter Settings window. You will see a prompt to select the IEC-61131 STRING type. Select either one CHAR per WORD, or two CHARs per word. Note that this must match the settings on the PLC, or string values may display incorrectly. The HMI will now automatically contact the controller and download any loaded tags for use immediately in the HMI project.
Place an Object and Link It to a PLC Tag
You can now configure any of the objects available in EBPro by simply placing the object, selecting your Allen-Bradley Controller as the device, and browsing to the tag you want to use.
Download the Project to the HMI and Connect to the PLC
Once you are ready, you can run the project in one of EBPro’s simulation modes or download it to an HMI for testing. To learn more about HMI project simulation, check out our Try Before You Buy page for more information.

Communication Cables
Selecting the correct communication cable is essential for establishing reliable communication between a Maple Systems HMI and an Allen-Bradley PLC. Different PLC models and communication protocols require specific cable types to ensure proper signal compatibility and data transfer.
Maple Systems HMIs connect directly to Allen-Bradley PLCs. Cable requirements may vary depending on the PLC model, communication method, and physical connection type used in your system.
To determine the correct cable for your specific HMI and PLC combination, use the HMI/cMT Cable Configurator.
