cMT Gateway products do not have any screens stored in them the way cMT Server products do, these gateways pull data from a controller and then send it upstream to your corporate network, but there are no built in visuals associated with the project. Integrating miscellaneous and older equipment for factory-level automation has never been an easy task. Since each machine uses different controller, when integrating with other IT/OT monitoring system, data transmission is limited because controllers use different protocols, and this is one of the obstacles that makes productivity improvement efforts ineffective and costly. With the de-facto IIoT protocols standard: MQTT and OPC UA built-in, our Gateway products fit into most applications and integrate real time data from different devices, to provide a standard communication interface. Our Gateway products support EasyAccess 2.0, a remote access service. Adding a Gateway product to your system allows access by users in a remote location, enabling users to obtain operation status of onsite machines, and maintain connected controllers.

Just as with all the Gateway products, the cMT-G01 supports the Modbus protocol. With cMT-G01 performing protocol conversion, upper management system can access any cMT-G01 attached controller simply by Modbus TCP/IP.

Communication Gateway is not only equipped with an Ethernet port, but also supports Wi-Fi, which enables it to communicate wirelessly when wiring may be limited by the environment.

Smart HMI Series Overview

Maple’s Smart series is designed to meet the expanding need for new ways to connect to equipment, while preserving the core functions of a fixed operator terminal. Learn more about how our Smart HMIs make it easy to monitor/control industrial processes from remote devices.

EasyAccess 2.0

What is EasyAccess 2.0?

Traditionally, HMIs were designed to connect only to local industrial control equipment such as PLCs or automation controllers. But the ever-increasing need for internet connectivity on the plant floor brings an increased demand for remote access to local HMIs and PLCs.

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.

Accessibility from devices outside the plant provides the opportunity to add new features to the Maple HMI/PLC by qualified personnel without ever leaving company headquarters. The ability to troubleshoot and reconfigure an HMI or PLC from a remote location greatly reduces the length of down time, travel, and personnel costs.

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.

EasyAccess 2.0 Enables Customers To:

  • Access, monitor, and control HMI screen activity as though you’re standing in front of the machine
  • Upload/download HMI projects to make changes and modifications to the HMI
  • Upload/download PLC projects using pass-through functionality built into the Utility Manager to troubleshoot PLC program issues

EasyAccess 2.0 allows you to instantly and securely communicate with your Maple Advanced HMI or cMT series HMI from anywhere in the world. Accessibility from outside the plant provides the opportunity to troubleshoot or add new features to the HMI/PLC program by qualified personnel without ever leaving company headquarters. An administrator grants access to specific HMIs and groups, and traffic is encrypted and secured with VPN. Remote troubleshooting saves money by reducing downtime, travel, and personnel costs. Note: EasyAccess 2.0 requires an activation card.

How do I implement EasyAccess 2.0?

Congratulations on deciding to implement EasyAccess 2.0. The day-to-day operations of your organization will soon be transformed – You’ll get to enjoy an operator’s view of the HMI without ever leaving company headquarters.

Below, find actionable steps to walk you through implementing EasyAccess 2.0. Doing so will enable you to remotely connect to HMIs and PLCs in the field for in-depth troubleshooting and monitoring. The steps outlined below are designed as a brief overview. For a more detailed explanation, please download our EasyAccess 2.0 Manual.

Step 1: Obtain Session ID and Password

A unique Session ID and Password is generated for each HMI that is connected to the EasyAccess 2.0 server. If an HMI is activated but does not belong to a domain, you can determine the Session ID and Password by downloading a project that allows access to the internet.

  1. First, create and download an HMI program that displays the Session ID/Password (system registers [LW-10821] to [LW-10827]), and allows setting LW-10820, the connection control register. The above setup is available in the EasyAccess 2.0 Demo project and the template files of the HMI (Window 76 – EasyAccess 2.0 Setting) .
  2. Let the HMI go online and connect to the EasyAccess 2.0 server by writing a “1” to [LW-10820] or clicking “Start” in the EasyAccess 2.0 Setting window.
  3. Once successfully connected, the HMI will display the Session ID/Password.

Note: It is also possible to determine the Session ID/Password using the EasyWatch application in the Utility Manager or the HMI configuration software.

EasyWatch allows users to monitor the HMI or PLC address values via Ethernet connection to the PC. For more information, consult the HMI Configuration Software Programming Manual.

Step 2: 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 selects users and HMIs to belong to the domain.

To create a new domain, go to the EasyAccess 2.0 Domain Management System (DMS) website:

Step 3: Activation

With the Session ID and Password, go to your DMS page and log in as the administrator. Under the “Devices” tab, click “+ Add HMI”, and then select “Add by session id/password” under Action Type. Enter the Session ID/ Password and notes if needed.

Continue to step 4 below.

Activate units using an EasyAccess 2.0 Activation card (separate purchase). See Products tab for complete list.

Step 1: Obtain Hardware Key

A hardware key is built into each and every HMI. However, the EasyAccess 2.0 feature is disabled by default on these units and must be activated in order to use EasyAccess 2.0. The HMI’s hardware key is located in configuration software’s local system settings menu. Select the EasyAccess 2.0 tab and locate the 30 digit hardware key. You may also find it under the systems register LW-11210 on Window 76 – EasyAccess 2.0 Setting.

Step 2: Activation

In order to use EasyAccess 2.0, you must activate the HMI. The HMI can be activated by purchasing an activation card from Maple Systems.

The activation code (from the activation card) and the hardware key (found in the HMI) are required to activate EasyAccess 2.0 in these units. If you wish to try EasyAccess 2.0 for free, a one-time, 30-day trial activation option is available when you create a domain account.

Step 3: 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 selects users and HMIs to belong to the domain.

To create a new domain go to the EasyAccess 2.0 Domain Management System (DMS) website: When an HMI is activated by activation card, it is automatically added to the domain under which it was activated.

Step 4: 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 5: Download and Launch EasyAccess 2.0

  1. Download EasyAccess 2.0 on your PC/ iPad/ iPhone/ Android Tablet.
  2. Launch EasyAccess 2.0.
  3. Enter the User ID at Once logged in, the program will list all HMIs assigned to this ID including all HMIs under an HMI group.
  4. Select an HMI and establish a remote connection.

You can now monitor any HMI in your HMI list.
Welcome to EasyAccess 2.0.

What are the Features & Benefits of EasyAccess 2.0?

EasyAccess 2.0 offers customers a wide range of features and benefits that can positively impact the way you run your organization. In addition, EasyAccess 2.0 provides several features designed to increase security, preventing unauthorized access to HMIs and the control systems they connect to.

Easy Access Ready: EasyAccess 2.0 is just one element of the bigger IIoT picture. It enables us to connect to remote devices and access data for analytical purposes to ultimately benefit our bottom line. All OEMs and systems integrators can and should be IIoT ready. Because eventually, most customers will pursue a connected factory. Thankfully, EasyAccess 2.0 comes pre-installed on new Maple Systems HMIs. Simply activate the feature on the customer’s device when the timing is right for them. For an extremely low cost, EasyAccess 2.0 can be an end-to-end solution for smaller-scale OEMS, even without using MQTT protocol.

Easy Setup: EasyAccess 2.0 is easier to install and operate compared to the previous version of EasyAccess (1.0) because there is no need to modify router settings, firewalls, or open up ports. Very little PC setup is also required. All you need to do is enable the EasyAccess 2.0 feature on the HMI and connect the unit to the Internet via Ethernet cable. It’s really that easy.

It’s Secure: In a time where security and “getting hacked” are of utmost concern, EasyAccess 2.0 employs several technologies to protect the HMI and its control network. All communications are done through VPN (Virtual Private Network) setup to prevent third parties from accessing private information. All data is encrypted using 128-bit SSL (Secure Sockets Layer) technology, which is commonly used in on-line banking. A proxy server option can also be used to conceal the identity of remote PCs. In addition, a Domain Management System (DMS) is required to designate authorized access of HMIs to specific users. In addition, the DMS is administrator-based and requires password protection for both the administrator and all users.

Preserves Bandwidth: Previously, EasyAccess (1.0) utilized a VNC server, which has a high bandwidth requirement. In addition to the live data, VNC would transfer the actual HMI screen and all of its graphics across the network, hogging bandwidth resources. With EasyAccess 2.0, a new HMI Viewer application has been integrated into the system. Only the actual live data is communicated across the network between the local HMI and remote device, preserving bandwidth and enabling faster data transfer.

More Efficient: EasyAccess 2.0 offers fast installation and set-up, faster operation, less strain on network bandwidth, and the convenience of instantly accessing your HMI from anywhere in the world. The new HMI Viewer takes a copy of live HMI data, sending only the data you need. In addition, Pass-Through mode enables quick and easy monitoring or updating of connected PLCs.

Saves Money: EasyAccess 2.0 reduces travel costs including gas, airfare, and overnight hotel accommodations. It reduces the cost of man-hours paid to send personnel onsite for troubleshooting and repair, as well as reduces the number of pricey technical support phone calls. But most of all, EasyAccess 2.0 will reduce the (very) expensive cost of downtime at the plant.

Better for Troubleshooting: With EasyAccess 2.0, you can easily monitor and troubleshoot HMIs/PLCs from a remote location as long as an Internet connection exists. EasyAccess 2.0 manages all network settings and security issues so the user simply connects to the HMI as if they were on the local network. Instantaneously view screens or implement updates to an HMI project or PLC. Change what is seen on screen LIVE by the operator, or, using the new HMI Viewer, update the project without disrupting what the operator is doing.

Reduces Down Time: Time is money. With EasyAccess 2.0 you can bring the plant up faster, minimizing expensive downtime. Consider a machine builder who sells machines with Maple HMIs installed. If a customer reports an issue, the machine builder remotely connects to the HMI using EasyAccess 2.0 and investigates the problem. He can quickly review and update the HMI project, monitor the PLC using Pass-Through mode, and even update the PLC program. With EasyAccess 2.0, you’ll enjoy the ability to resolve your problem almost as quickly as it occurs.

Monitor & Control with EasyAccess 2.0

EasyAccess 2.0

OEMs and large organizations need a way to connect to, monitor, and control devices that may be scattered across the globe. EasyAccess 2.0 is an out-of-the-box solution that requires little to no network set up at the site of installation, yet can be used to monitor and control your cMT solution without ever leaving the office.

EasyAccess 2.0 works by allowing the cMT device to reach out and register itself on a known, fixed, cloud-based web server. Access to the cMT HMI can be managed through a simple web interface. This allows companies to assign a particular set of HMIs to groups of EasyAccess 2.0 users. Users can then utilize one of several EasyAccess 2.0 client applications to connect to the cMT device through a secure VPN connection, allowing them to view and control the HMI project as if they were standing in front of the machine. EasyAccess 2.0 client applications are available for Windows PCs, Android devices, and Apple iPads/iPhones.

This easy to use solution brings the power of the IIoT to your product line without needing to integrate different software packages, or program a custom solution from scratch. OEMs can remotely manage their products post-sale after they’re installed, with minimal need for network set up at the customer’s site. This can save the enormous expense of onsite service calls. Large organizations with many devices in the field can have an instant window into any machine with an internet connection.

Application Solutions

Solution 1: Local Machine Control

New technologies bring new ways of interacting and controlling systems, but the need for a static HMI that is always ready and available will not go away. While cMT Series HMIs enable new and exciting features, the cMT Series also does not compromise on fulfilling this vital role.

The cMT Series uses EBPro, the next iteration of configuration software that Maple Systems customers use in our Advanced and Basic models. This software platform allows interface designers to select from over 300 protocol drivers and connect to nearly every PLC available in the automation market place today. With data from these devices, automation engineers can quickly construct state-of-the-art interface screens that present data to the operator in intuitive ways, so they’ll know exactly what’s going on within their machine. All of the standard display and data entry objects are available: buttons, meters, trends, alarms, and much more.

Once the project is designed, choose from one of our 4 Touchscreen cMT model sizes (7″, 9.7″, 10.1″, or 15″). These units can be mounted in a control panel like any traditional HMI. cMT Servers, which do not have a built-in display, can be paired with a cMT-iV6, a 9.7″ touchscreen display or a cMT-iM-21, a 21″ touchscreen monitor. Each can be a mounted in a traditional control panel. These screens provide a permanent fixed terminal that operators expect to find in any system. These screens provide a permanent fixed terminal that operators expect to find in any system.

Solution 2: Adding Remote and Mobile System Displays

A static, panel-mounted display is great for many applications but can be limiting in others.

For example, a machine may be quite large and the operators want to be able to stand directly in front of the section of the machine they are working on. Previously, the only way to accommodate this need would be to install a separate control panel at every point of interest along the assembly line. Or, a plant manager may want the ability to quickly log into any plant floor machine in order to respond to issues and monitor production rates. cMT Series HMIs allow you have it either or both ways.

Wireless Access to Remote Displays

The cMT Viewer application enables operators to use wireless Android, Apple, or Windows® tablets as their HMI. They are untethered from the control panel. The operator can move freely to any part of the assembly line or processing plant, taking their HMI with them. This eliminates the need for running back and forth to the panel while troubleshooting, or tying up two operators; one at the control panel pushing buttons, and the other at the machine troubleshooting equipment.

The cMT Viewer application can also be run on any Windows® PC – any computer on the same network as a cMT HMI can easily view and control the system. A plant manager can connect to any cMT HMI in their plant to get a real-time view of exactly what is occurring with that machine. The connection is password protected so only authorized users can have access. The Monitor Mode feature in cMT Viewer allows plant managers to view live data from up to 50 connected cMT devices simultaneously.

An alarm condition from any device would immediately alert the operator, enabling quicker response rates and resolution to the issue. The cMT Viewer application can run on a traditional Windows desktop or on panel PC to provide a supervisory control station with access to many subordinate machines.
Explore cMT Viewer.

Solution 3: Data Management

The HMI view of an operator interface terminal, whether on a local display, mobile tablet, supervisory panel PC, or remote workstation, is only one view of the important data in an automation system. There are also; alarm and data logging, database integration, recipe management, protocol translation and more. cMT Series Products prove to be a flexible tool in these areas as well. Let’s tour a few features available to manage your data on the cMT products:

Modbus Gateway

In an ideal world, every machine vendor and systems integrator would use the same protocol and all equipment would seamlessly communicate with everything else on a plant floor. More often than not, this is far from the case. As a plant grows over time and different systems are added, little thought is given to the process as a whole. You’ll often find different systems, from different manufacturers, speaking different protocols, on different serial busses. Fortunately, cMT products speak many languages. cMT Series Products can use over 300 protocols on any of the available com ports, and translate them to the default industrial standard protocol: Modbus TCP/IP. The cMT device becomes a transparent protocol translator, allowing upstream SCADA systems to connect to PLCs as if they were all using the same protocol on the same bus.

Modbus Communication Gateway

Database Object Increasingly, data that machines produce needs to be recorded and preserved. The data may be useful in process improvement or may be required by regulatory agencies. The cMT products have an object which allows them to log a data sampling object or an alarm log directly to an SQL database server over an Ethernet LAN.

This eliminates the need for manually retrieving and entering log files from each machine independently. Data from many different sources can be aggregated and stored in one central safe and secure location, automatically.

Databases and Recipes Recipes are a collection of parameters stored in the HMI that can be transferred to a machine with one press of a button. Different parts may require different amounts of material, different cook times and temperatures, or different processing steps. This data often needs to be shared across multiple machines that may be at different steps in the process, or may be redundant production lines working on producing the same or similar products.

SQL databases can act as a storage tank for all machines sharing a particular recipe database. cMT HMIs can query the database for current recipe data before sending those parameters to the PLC. This way, changes only need to be made to this central database, instead of manually changed in each HMI.

This feature saves time in systems that have many machines sharing many recipes. The changes, additions, and deletions to the database only need to be made in one place and are then automatically updated throughout the system. This ensures production uniformity throughout the system. A single machine will not get stuck using an outdated recipe simply because someone forgot to update it.

Solution 4: IIoT Gateway

So far we have seen how the cMT series of products work as a local display, a mobile HMI server, and a data manager within the factory. But the cMT series packs even more features that enable yet another level of access and control. The IIoT, or Industry 4.0, is a growing area of interest in the automation market. The cMT series provides a capable, ready, and secure solution for the IIoT.

Open Platform Communications (OPC) Unified Architecture (UA) is a tried and tested communication protocol supported by many SCADA, MES, and ERP software providers. The protocol has built-in security with signed and encrypted data transfer using state-of-the-art encryption algorithms. Data is organized into browsable objects, making it easy to both access data and quickly understand how to use what the data represents.

Any data accessible to the cMT can be added to the OPC UA server to be accessed by upstream devices. The configuration interface required to add data to the OPC UA server is very simple and straightforward to use. The user can organize data into multi-level objects with descriptive names. An OPC UA client device connecting to the cMT will see data organized in the same intuitive way.

MQTT is a powerful and efficient IoT protocol that is lightweight, highly scalable, and has excellent support on many client devices and programs. MQTT integrates well with Amazon AWS, IBM Bluemix, and Microsoft Azure cloud hosting services for next level data collection and processing.

The cMT Series Smart HMIs offer a full featured MQTT implementation. An easy to use configuration interface allows the user to select data from any of the supported PLC drivers, add it to an MQTT topic, and publish it periodically or whenever values change. The cMT Series can also subscribe to MQTT topics and write the received data to internal HMI memory or to PLC memory addresses. And as well, cMT Series HMIs can host an MQTT broker internally, coordinating connections from other Maple Systems HMIs or any other MQTT enabled device.

cMT HMIs offer advanced integration with Amazon AWS’s Device Shadow service which creates a virtual representation of the actual device in the cloud. And EBPro supports the Sparkplug B MQTT payload specification for integration with Ignition SCADA software and other Sparkplug B compatible software programs.

The MQTT protocol is data agnostic, meaning that any data can be sent through the protocol, including plain text messages. This raises security concerns since anyone with access to the network can view the data in transit. However, the MQTT feature on Maple Systems products includes the ability to encrypt messages from publisher to subscriber. This ensures that messages are only read by the people and programs authorized to receive the messages.
