How do I get started with CODESYS on Maple Systems devices?
First you’ll want to make sure your device supports CODESYS:
Next, you’ll need to install the CODESYS Development System on your PC. This installs the IDE only, not the runtime on your device (we’ll get there):
- Go to Maple Systems Software Downloads and Upgrades
- Click on the download link for CODESYS IDE (32bit or 64bit)
Then, make sure to install our add on package. This ensures CODESYS knows how to talk to your cMT device:
- Go to Maple Systems Software Downloads and Upgrades
- Click on the download link for CODESYS & Remote IO Package
Now, we’re going to install and update the CODESYS Runtime on your Maple Systems device:
- If you don’t have EBPro installed, go to Maple Systems Software Downloads and Upgrades and click the download link for EBPro.
- Once that’s installed, open EBPro Utility Manager and choose the model number of the device you’re using.
- Select CODESYS Firmware Upgrade. The latest Firmware can be found in the Software Downloads and Upgrades page.
Your HMI has now become a PLC runtime that can execute IEC 61131-3 Logic!
Ensure your PC and cMT device are on the same network/subnet. Your device will show a CODESYS runtime IP address on the screen, you’ll need this IP to connect from CODESYS IDE.
To create a new CODESYS project, in the CODESYS IDE system:
- Click on File – New Project
- Choose the model number (this will only show up after you’ve installed the CODESYS & Remote IO Package)
- Select your preferred programming language (LD, ST, FBD, SFC, etc.)
Now you’re ready to create your project, download it, run and debug!
I need to use an IP camera and other peripherals in my project. Do Maple Systems HMIs support these devices?
Yes. Maple Systems HMIs are compatible with a wide range of peripheral devices such as printers, barcode scanners, cameras, keyboards, mice, flash storage drives, and more. For projects using multiple USB devices at once, a USB hub can expand a single USB port into many, allowing several devices to connect simultaneously.
Note: USB ports on Maple HMIs do not support charging for mobile phones, tablets, or unpowered speakers. The USB ports on our HMIs are for data storage or keyboard/mouse connection only. Using the ports in a manner inconsistent with their documented purpose can potentially damage the device.

How do I implement EasyAccess 2.0 on my Maple Systems HMI?
Implementing EasyAccess 2.0 is easy. For complete instructions, refer to the EasyAccess 2.0 Manual available in our Support Center. Step 1: Create Domain Account:An HMI must belong to a domain in order to use EasyAccess 2.0. Anyone can create a new domain for free, all you need is a valid e-mail address. The Domain Management System is the basic system used to organize and handle HMI’s under a particular domain.
An Administrator then runs the domain and adds users and HMIs to the domain. To create a new domain go to the EasyAccess 2.0 Domain Management System (DMS) website (https://account.ihmi.net). Step 2: Manage Your Domain:When you create a domain account, you become the domain’s administrator. It’s the administrator’s responsibility to create new user accounts and to assign HMIs to specific users and HMI groups. Your domain can contain multiple HMIs, groups, and users.
Step 3: Activation:In order to use EasyAccess 2.0, you must activate the HMI in the domain. Some HMIs have EasyAccess 2.0 pre-installed and some require purchasing an activation card.
For HMIs requiring an activation card: The HMI can be activated by purchasing an activation card from Maple Systems. The activation code (from the activation card) and the hardware key are required to activate EasyAccess 2.0 in these units. The HMI’s hardware key is located in the HMI’s system settings window. Select the EasyAccess 2.0 tab and locate the 30 digit hardware key. You may also find it on Window 76 – EasyAccess 2.0 Setting. Select “Add HMI” in the domain and enter the hardware key and activation code. When an HMI is activated by an activation code, it is automatically added to the domain under which it was activated. Open window 76 – “EasyAccess 2.0 Setting” on the HMI. With the HMI connected to the Internet, push the Start button to initiate the connection to the EasyAccess 2.0 server. For HMIs with EasyAccess 2.0 pre-installed: The HMI can be activated by obtaining a Session ID and Password from the domain. Open window 76 – “EasyAccess 2.0 Setting.” With the HMI connected to the Internet, push the Start button to initiate the connection to the EasyAccess 2.0 server. If the HMI has not been assigned to a domain yet, a Session ID and Password will be assigned to the HMI and appear on window 76. Select “Add HMI” in the domain and enter the Session ID and Password. It should now be added to the domain. Step 4: Download and Launch EasyAccess 2.0:Download the EasyAccess 2.0 app on your PC/ iPad/ iPhone/ Android Tablet, Launch EasyAccess 2.0, enter the User ID and password. Once logged in, the program will list all HMIs assigned to this ID including all HMIs under an HMI group. Select an HMI and establish a remote connection. You can now monitor any HMI in your HMI list.

What libraries are compatible with the cMT CODESYS runtime?
The cMT series‘ built-in CODESYS runtime is compatible with wide range of standard libraries and features available in CODESYS IDE, with some limitations. Generally, libraries that do not require OS and hardware support are compatible with the cMT series’ CODESYS runtime.
The table below lists libraries known to be compatible with the cMT series’ built-in CODESYS runtime:
| Sys Library | Cmp Library | CAA Library |
|---|---|---|
| SysTimeRtc | CmpTraceMgr | CAAType |
| SysTimer | CmpSrv | CAATick |
| SysTime | CmpSettings | CAATickUtil |
| SysTask | CmpSchedule | CAAStorage |

Libraries incompatible with the cMT series’ CODESYS runtime can be added to a CODESYS IDE project and compiled or downloaded without issue. However, they may cause “unresolved reference” errors when logging in via CODESYS IDE, or certain function blocks may not operate correctly, leading to compile errors. This indicates incompatibility, and such libraries should be removed from the project.
Compatible libraries may still have limitations. For instance, using the SysTimeRtcSet function from the SysTimeRtc library will result in a “Not implemented” error in CODESYS IDE, as the cMT’s CODESYS runtime does not control the hardware clock.
The cMT series’ built-in CODESYS runtime does not support the following features:
- OPC UA features
- Network Variable List
- Alarm Configuration (Alarm Manager)
- Redundancy Configuration
- CODESYS TargetVisu
- CODESYS WebVisu
- CODESYS HMI
- SoftMotion
- CODESYS IIoT Libraries SL
- CODESYS OPC UA Client SL
- CODESYS OPC UA Server SL
- CODESYS Safety for EtherCAT Safety Module SL
Note: It is always suggested users verify functionality of any CODESYS IDE logic prior to using external libraries & function blocks in a production environment.
