Migration of telemetry systems. Evolution from MT-101 to  MT-121


In today’s fast-paced industrial world, the migration of telemetry systems and control equipment to newer technologies is becoming not just an option, but a necessity. These changes allow for increased efficiency, reliability and safety in industrial operations. An example of such a transformation is the evolution from the MT-101 telemetry module to the MT-121, which perfectly illustrates the benefits of modernisation.

The origins of MT-101 telemetry

In 2002, the MT-101 telemetry module made its market debut as a simple tool for sending short SMS messages. Initially it served a modest function, but over the years it has undergone a remarkable transformation. It has evolved from a simple controller into an advanced, reliable unit that has become the foundation of many telemetry systems. Thanks to its ability to integrate measurements from a variety of devices, the MT-101 has gained status as the heart of autonomous industrial facilities, enabling precise monitoring and management of processes in real time. Today, it exemplifies the dynamic development of telemetry technologies to meet the growing demands of modern industry. Despite the passage of years, the MT-101 is still in operation at thousands of installations around the world, a testament to its reliability and durability.

New generation MT-121 modules

As is usually the case with technological developments, the availability of modern components and increasing market demands meant that the well-deserved MT-101 device lived to see its successor, the MT-121. The new design gained a number of improvements that allowed even more efficient integration with various systems, as well as the implementation of more advanced operating algorithms. The MT-121 introduced new functionalities and higher performance, while maintaining the reliability that was the hallmark of its predecessor. 

How we upgraded the MT-121?

The MT-121 offers a number of improvements over the MT-101 that translate into real benefits for users: 

  • 4G network support The MT-121 is aligned with the latest communication standards for faster and more stable data transfer. Integration with the 4G network is crucial for effective real-time monitoring and management of processes, especially in extensive and remote locations. The process of GSM network operators switching off older 2G and 3G technologies is also an important aspect. 
  • Advanced development tools – With CODESYS® support, the MT-121 offers new, advanced development tools to create more complex and customised applications. CODESYS® is an IEC 61131-3 compliant development environment, making it easier to create, test and deploy control software. 
  • Chassis compatibilityKeeping the chassis the same dimensions as the MT-101 greatly simplifies the process of replacing the unit in the control cabinet. This minimises downtime and installation costs. In addition, the almost identical arrangement of the signal connectors and at least the same number of I/O resources make the migration easier, and the entire replacement process runs smoothly and without unnecessary difficulties. 
  • Extended inputs/outputs The MT-121 offers more analogue inputs/outputs (3xAI 4-20mA and 1xAO 4-20mA), allowing more sensors and measuring devices to be connected. This allows for more accurate monitoring of industrial processes and easier expansion, resulting in better control and optimisation of system operation. 
  • Logger functionalityThe built-in data logger increases the reliability of data delivery, which is crucial in critical industrial applications. The logger allows measurement data to be stored in the unit’s local memory, ensuring availability even if the network connection is lost. 
  • Ethernet port – allows easy connection to the local network and integration with other systems. The Ethernet port ensures fast and reliable data transfer, which is particularly important in industrial environments. 
  • Dual-SIM functionality – the ability to fit two SIM cards (passive Dual-SIM) increases the reliability of communication, enabling automatic switching to the second card in the event of failure of the first. 

 

Why migrate?

There are a number of benefits to migrating to newer platforms, such as the MT-121: 

  • Improved efficiency – modern equipment offers higher performance and faster processing, resulting in better monitoring and management of processes. 
  • Advanced monitoring and diagnostic capabilities The MT-121 offers enhanced tools for monitoring and diagnosing device status. These features enable rapid detection of potential problems before they become major failures. Ongoing tracking of operating parameters allows for faster responses, minimising downtime and reducing operating costs. 
  • Increased security for telemetry processes – modern devices such as the MT-121 offer not only new security features and regular software updates, but also advanced data encryption and communication protocols. In the face of growing cyber threats, these enhancements provide a higher level of protection against unauthorised access and potential attacks, which is crucial for continuity of operations and the protection of sensitive data. 
  • Easy integration with other systems – with support for modern communication standards and new interfaces, the MT-121 integrates seamlessly with other industrial automation components. This integration allows for more advanced data analysis and enterprise-wide process optimisation, leading to even greater efficiency. 
  • Support and Service The MT-121 is actively manufactured by Inventia, ensuring stock availability and rapid service in the event of failure. As a result, users can count on a smooth repair, using original components. Unlike older models, whose parts may no longer be available on the market, the MT-121 guarantees continued support and trouble-free operation for many years. 

The migration of telemetry systems from MT-101 to MT-121 is a natural step in the evolution of industrial technology. New functionalities, higher performance and better integration with modern systems translate into real benefits for users. With the development of GSM technology, the future of industrial telemetry looks even more promising, offering even greater opportunities for real-time monitoring and process management. 

How to carry out the migration process?

Each installation has unique characteristics depending on the specifics of the company in question and therefore requires an individual approach. Nevertheless, a few key elements can be identified. Migrating from MT-101 to MT-121 requires careful planning, taking into account technical and organisational aspects. The first step is a system audit to identify strengths and areas for improvement. Next, the needs of the business and the capabilities of the new device, the MT-121, should be analysed. The next step is detailed migration planning, including configuration, installation, integration and testing. The process should be staged to minimise the risk of disruption, and staff should be trained accordingly. After installation, testing is carried out, optimising the system to realise the full potential of the MT-121. 

Why the MT-121 and not another device from the product portfolio?

What if MT-121 does not have enough resources?

If this is the case, you should consider choosing the MT-151 LED or MT-151 HMI devices. If you have any doubts or need help, take a look at the device selection file we have prepared or contact the Inventia team.
