Siemens S7-200 Connection Guide
Our Siemens S7-200 connection guide is here to provide you the necessary information to connect your Maple Systems HMI to a Siemens S7-200 Series PLC. Every resource you need to get communications up and running, including:
- Quick Start Guides
- Demo Project
- Controller Information Sheets
- Communication Cable Configurator
Maple Systems is dedicated to making integration between your devices as straightforward as possible. In this guide, we’ll provide a comprehensive overview of how to establish communication between a Maple Systems HMI and a Siemens S7-200 Series PLC. From configuring the network settings to importing tags and verifying data flow, this guide has everything you need to get started.
Quick Start Guides
Our Quick Start guides are here to help you get your HMI and PLC talking to each other quickly and painlessly. Click on the button below to show more details for the protocol you are using, and learn how to connect your devices in five easy steps.
Serial
Follow these steps to set up a serial connection to your S7-200:
Open the EBPro application and start a new project, or load an existing one.


In the System Parameters window, click New Device/Server and select the Siemens S7-200 driver.


Open the Settings menu to configure the communication settings for the Siemens PLC. These settings must match what has been configured for the PLC, or communication errors may occur. Once these are set, press OK to confirm.


Once you have configured the communication settings, you may now assign objects to read or write to addresses on the PLC. Let’s add a Bit Lamp object to our project to use as an example. To do this, navigate to the Object menu and select the Bit Lamp object. In the properties window, select the Siemens PLC from the Device dropdown, then configure the register type and address.


Once you are ready, you can run the project in one of EBPro’s simulation modes or download the project to an HMI for testing. To learn more about HMI project simulation, check out our Try Before You Buy page.

For more details on how to establish communication with an S7-200, please refer to our Controller Info Sheet for this device model.
Ethernet
Follow these steps to set up an Ethernet connection to your S7-200:
Open the EBPro application and start a new project, or load an existing one.


In the System Parameters window, click New Device/Server and select the Siemens S7-200 Ethernet driver.

Note: Siemens S7-200 requires the use of a CP243.1 module to communicate over Ethernet.

Open the settings menu to configure the communication settings for the Siemens PLC. These settings must match what has been configured for the PLC or communication errors may occur. Once these are set, press OK to confirm.


Once you have configured the communication settings, you may now assign objects to read or write to addresses on the PLC. Let’s add a Bit Lamp object to our project to use as an example. To do this, navigate to the Object menu and select the Bit Lamp object. In the properties window, select the Siemens PLC from the Device dropdown, then configure the register type and address.


The Siemens S7-200 is now ready to use within your EBPro project. Once you are ready, you can run the project in one of EBPro’s simulation modes or download the project to an HMI for testing. To learn more about HMI project simulation, check out our Try Before You Buy page.

Demo Project
Our EBPro S7-200 demo project has been preconfigured to to communicate with a Maple Systems HMI, and demonstrates the usage of multiple EBPro features. Play the video below to see a preview of this demo project in action, then follow the instructions to install and run the project on your development PC.
Follow the steps below to open this demo project in EBPro:
- Download the compressed S7-200 Demo Project folder.
- Extract the files from the zipped folder and save them to a local drive on your PC.
- Open the EBPro configuration software.
- Open the FILE menu and select Compress/Uncompress.
- In the Uncompress section of the window, click Browse, then select the Siemens_S7200_Pump_Demo_EBPro.ccmp file that was just extracted from the zipped folder in step two. Click Uncompress.
- The uncompressed project file will now be saved in the same location as the .ccmp file with a .cmtp file extension.
- Use File > Open in EBPro to open the uncompressed project file.
