Are you still using EZware Plus?
You can quickly convert and import your existing EZware Plus project into EBPro with a few simple steps:
- Download both software versions for FREE, from our Support Center.
- Follow Tech Note 5125 to convert your project.
What if I have multiple older HMIs still in operation out in the field?
You will have to maintain separate projects. Once your project is converted from HMI series to cMT series, it cannot go back to HMI. If project updates are needed, make sure to update the HMI project first, save it, then convert that to cMT, and save that separately.
Can I use a headless HMI without a display?
Yes, our headless (without an integrated display) units are fully functional HMIs. Utilizing EBPro software, you can configure the headless device to communicate with your PLC/controller the same way you would program any Maple Systems HMI. If a display is required, a Windows® PC, Apple or Android smart device, or one of our Web HMI’s can be used. The CMT-FHDX devices can be paired with any HDMI supported Monitor or large screen TV, as well as your Windows PC.Can I use a Smart Phone to communicate with a Maple Systems cMT HMI?
Yes! The free cMT Viewer app is available for both Android and Apple smart devices. Simply download the app and connect to the same local network as your cMT HMI. You will then be able to browse to your HMI in the app, download the project, and then control your system from your phone.What is EasyAccess 2.0?
EasyAccess 2.0 offers the ability to remotely monitor and control a Maple Systems HMI and connected PLC from literally anywhere in the world.EasyAccess 2.0 integrates perfectly with a wide variety of displays including desktop PCs, laptops, tablets, and smart phones, making it easier than ever to connect to operational equipment in the field. What if you could instantly access display information from a plant floor HMI or PLC from the comfort of your office, your living room, or even thousands of miles from the factory?
With EasyAccess 2.0, all of this and more is possible. A remote supporting service, EasyAccess 2.0 offers the ability to easily monitor and troubleshoot Maple Systems HMIs (and connected PLCs) from a remote location as long as an Internet connection is available. Similar to instant messaging software such as Skype, Facebook Messenger, or WhatsApp, EasyAccess 2.0 allows you to instantly communicate with your HMI without spending time memorizing the HMI’s IP address, or configuring complicated port mapping.
As its name implies, EasyAccess 2.0 makes remote monitoring and troubleshooting Maple Systems HMIs efficient and easy.

Why would I use a HMI without a display?
Select Maple Systems’ HMIs without a display is a great solution if you need a gateway between your control system and the supervisor’s office. Many MES (Manufacturing Execution Systems), ERP (Enterprise Resource Planning), SCM (Supply Chain Management), and MRP (Material Requirements Planning) software does not support the myriad of communication drivers used in industrial PLCs, and therefore are unable to collect data directly from the plant floor.
However, most do support Modbus TCP/IP protocol since it is widely used, non-proprietary, and openly available. Add a headless HMI to your control system, using one of the Ethernet ports to connect it to the corporate LAN. The headless HMI will collect data from the plant floor, translate it to Modbus and send it to the office computer.
Why would I use a headless HMI unit instead of a touchscreen HMI?
Most HMIs have a built-in touchscreen to provide feedback and allow input from on-site personnel. If that is all that’s required, a standard HMI may be sufficient. On the other hand, if you have limited panel space, no need for a touch screen, and want the convenience of monitoring and accessing your system without having to walk to where the HMI is physically located, one of our headless HMIs would be a great option. Utilize your Apple or Android smart phone or tablet to access unit remotely.Software
