How EasyAccess 2.0 Works

EasyAccess 2.0 provides a new way of accessing a Maple Systems HMI from anywhere in the world, as long as an Internet connection is available. Since EasyAccess 2.0 manages all network settings and security issues, the user simply connects to the HMIs as if they were on the local network. Moreover, it is possible to have access multiple HMIs within a network. With EasyAccess 2.0, the ability to remotely connect to HMIs is much easier, more secure, and more flexible than ever before.

System Requirements:

  • Maple Systems HMI with EasyAccess 2.0 feature activated
  • An Internet connection
  • PC Operating Systems: Windows XP, Windows 7, Wndows 8 (32/64 bit)
  • Software version v4.10.05 or later
  • iPad Tablet: iOS 7.0 or above
  • Android Tablet/Phone: V4.1.2 or above

Pass-Through Technology

Remote pass-through is made possible and simple with EasyAccess 2.0 by utilizing the aid of a program that is included with our configuration software. EasyAccess 2.0 uses the highly secure SSL VPN technology (Secure Sockets Layer Virtual Private Network), giving you the ability to monitor and update a PLC connected to your remote HMI. Simply link in, upload/download the PLC project, or go online to see what’s on the HMI. You can even control it using your mouse or keyboard, it’s like you’re in front of the HMI. During the pass-through process, communication between the HMI and PLC remains and the remote user can see the PLC’s updated status as soon it’s changed.


VNC is an RFB (Remote Frame Buffer) protocol used for remote operation and screen sharing. It enables you to instantly and easily monitor and control a remote HMI as though you were standing in front of it. Enjoy an operator’s view from literally anywhere in the world.


EasyAccess 2.0 uses a VPN which establishes a virtual private network over the public Internet to securely transmit encrypted data to your internal network. Doing so ensures the same security and reliability you’ve come to expect when transmitting online banking data. Features include:

  • SSL 128-bit Encrypted Tunnel
  • Supports Log-In Authentication
  • Supports PC/Panel PC/Android Tablet/iPad
  • Proxy Option (Let’s you set up a separate computer to act as a proxy server)
  • Supports Pass-Through Mode, VNC, and cMT Viewer Applications

HMI Manager

The HMI Manager is essentially a project management tool enabling easy management of your Easy-Access 2.0 HMI fleet. Use the HMI Manager to control elements including:

  • Add or delete new users and HMIs
  • Manage HMI names, locations, and notes
  • Grant or restrict operator access to an HMI(s)
  • And more

cMT Viewer

cMT Viewer is a GUI remote connection software with the ability to run on PCs, Panel PCs, iPads, and Android tablets. cMT Viewer is included with EasyAccess 2.0, enabling quick and easy monitoring of a single machine, or up to three different machines simultaneously. cMT Viewer is available as a free download from the iTunes and Google Play stores for Apple iPad and Android devices. The look and operation of the application is seamless across all platforms.

When cMT Viewer initially connects to the remote HMI, project data is transferred into the cMT Viewer application. cMT Viewer then displays screen information independent of what is shown on the HMI. Only the live data is transferred across the network between the cMT Viewer and the HMI, greatly preserving system bandwidth.

Upon opening EasyAccess 2.0, all remote and EasyAccess 2.0 activated HMIs are automatically detected and shown in a list. Simply search the list, select the desired HMI, and press the cMT Viewer button. This will download the unit’s project and instantly display real-time data from the HMI.
