Technological advances in the fields of IT, personal electronics, and manufacturing are expanding the role of the traditional Human Machine Interface (HMI) in the automation market. Today there are many more ways in which humans can and want to interface with their machines. It is no longer just an operator physically standing in front of a machine using a touchscreen to control basic operations. HMIs must network to a central location where a plant manager can monitor operations efficiently and receive quick alerts to resolve maintenance issues. OEMs need to monitor and track their equipment remotely and respond to problems without making onsite visits. And machine operators who want to be free to walk around the facility controlling their machines via tablets and smartphones.
What is cMT?
cMT = Control and monitor, from the plant floor and beyond. Our innovative cMT solutions make it easy to monitor/control your industrial process from remote devices such as PCs, smart phones, and tablets.
- The cMT-SVR connects to your PLC and connects wirelessly to PCs, Apple/Android tablets, and Apple/Android smart phones to provide instant access to your industrial control system. The cMT-SVR is an HMI without a built-in display. Perfect for systems where a local visual interface is not required, this option provides all of the features of an HMI plus remote connectivity at an extremely affordable price. However, if a local display is still needed, the cMT-SVR can be paired with the 9.7" panel-mounted display (cMT-iV5) to provide a traditional touchscreen interface. The cMT-SVR-OPCUA offers the same functionality of the cMT-SVR, but with OPC-UA functionality.
- Want server functionality and a display? The cMT series offers 4 display sizes to meet every need. 7.0", 9.7", 10.2" and 15.0" touchscreen displays can easily accommodate even the most complex control systems. These powerful displays offer all of the features and capabilities of Maple's Advanced HMIs, plus they possess a built-in cMT-SVR.
- If an IIOT gateway with HMI data processing capabilities is what you are looking for, explore the cMT-G01 and the cMT-G02. Both models offer Built-In MQTT, Built-In OPC-UA, and PLC Pass Through and Push Notifications via EasyAccess 2.0. In addition, the cMT-G02 supports Industrial Wi-Fi. The detachable antenna allows using a third-party antenna suitable for the environment.
- The cMT-HDMI is a powerful HMI without a touchscreen. With full HD 1080p High Resolution HDMI Output and support for customized resolution for 16:9 / 4:3 LCD monitors, you can easily connect to one of our industrial display models. With USB and Serial communications, plus dual Ethernet ports, the cMT-HDMI adds flexibility and functionality that you just can't get with a traditional HMI touchscreen.
In addition, your HMI application can be viewed on a PC connected via the cMT Viewer client application. This same application can also be shown on a variety of different display devices, e.g. PC, Panel PC, iPad, iPhone, or Android tablets. This means that organizations can implement a flexible combination of cMT products with different display devices according to their unique application and user needs. Up to three different display devices can be connected to each single cMT device at one time.
The cMT series includes cMT Server software which communicates to the cMT Viewer application that resides on a remote PC, mobile phone, or smart tablet. This simple innovation makes it much easier to monitor your control system from a remote device.
cMT Product Architecture
Moving beyond the traditional HMI interface view, cMT series products offer additional IIoT features that make it much easier to extract data from the automation plant:
- An MQTT server: Publish, subscribe, or host a broker on board
- OPC UA server
- Remote Secure Access via EasyAccess 2.0
- MySQL database connection
- Email alarms and data logs
- Modbus TCP gateway
- And more
This innovative architecture leverages the use of our Advanced HMI's and the cMT series in many industrial automation applications such as marine, oil & gas, metals, smart home, smart factory, and many more. Weintek's cMT series of HMI products offers four main solutions (detailed below) that can increase your company's competitive edge.
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 always resides in the same location remains. While enabling new exciting features, the cMT series 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.
To display the HMI screens, choose from one of our 4 sizes. Each offers a built-in touchscreen display. These units can be mounted in a control panel like any traditional HMI. The cMT-SVR, which does not have a built-in display, can be paired with the cMT-iV5, a 1024 x 768 pixel resolution, 9.7" touchscreen display. The cMT-iV5 can be a mounted in a traditional control panel, or on a VESA display mount. 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. The cMT series allows you have it either or both ways.
The cMT Viewer application enables operators to use wireless Android or iPad 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 trouble-shooting equipment.
Wireless Access to Remote Displays
The cMT Viewer application can also be run on any PC. This means that any computer on the network with a cMT device can easily view and control the system. A plant manager can connect to any cMT in their plant to get a real-time view of exactly what is occurring with that machine. Connection to the cMT is password protected so only authorized users can have access. Another cMT feature, Monitor Mode, 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.
Support for Multiple Simultaneous Display Platforms
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. The cMT series proves 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:
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,the cMT products speak many languages. The cMT 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 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
Recipes are data that machines need to perform their everyday operations. 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.
The cMT series can act as a storage tank for all machines sharing a particular recipe database. The recipe resides on the cMT. When a change is made to this central database the change is automatically downloaded to any HMI client using that recipe.
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.
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.
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.
OPC UA (select models)
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 objects making it easy to both access data and quickly understand what the data represents and how to use it.
Any data accessible to the cMT can be added to the OPC UA server and accessed by an upstream device. 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 architecture consists of three main components:
- Subscriber - a device that listens for data sent on a particular MQTT topic
- Publisher - a device that produces data for a particular topic and sends it to a central broker
- Broker - a central component that manages connections and exchanges data between publishers and subscribers
The cMT series of HMIs are enabled to fill any or all of these roles. 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. Finally, the cMT series can host an MQTT broker internally, coordinating connections from other Maple Systems HMIs or any other MQTT enabled device.
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.
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 solutions 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 cMTs (or HMIs) 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.
Remote Access with EasyAccess 2.0
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.
Maintaining the Control Network's Integrity and Security
Automation networks have special requirements for real-time data delivery and security. The features discussed above and others put demands on the control network that should not interfere with the primary task of the network, which is keeping the machine operating efficiently and safely. Select cMT series products have dual-Ethernet ports and other security features built in. Dual-Ethernet means that one port can be used for an internet connection while the other is dedicated to the real-time task of PLC communication. For OEMs this means they can have an internal EtherNet/IP, Profinet, or Modbus TCP/IP network dedicated solely to machine operation that's never connected to their customer's network, yet still provide the remote connectivity features their customers demand.
