Siemens S7-300/ET 200M to be phased out by 1 October

The Siemens SIMATIC S7-300-PLC and its ET 200M IO system are nearing the end of their product life cycle. Per 1 October 2023, these proven product families will be phased out. To fully meet new handling and performance requirements, Siemens has developed controllers with improved system features: the S7-1200 and S7-1500, which can be programmed in the TIA Portal software platform.

It is good to start thinking about an effective replacement strategy now. itsme can support you in this. For example, with a FactoryScan. With this, we map out the installed base and make a risk analysis of the components. This reveals the best options to prevent costly production process downtime. Whether it is about creating a local own stock or converting a critical installation, itsme can help you determine the optimal approach.


A switch to the new controllers offers many advantages. For example, the flexible and efficient S7-1200 is easy to expand with specific modules, such as an energy meter and condition monitoring system. It has one system for standard and safety applications and is easily upgradable to the S7-1500. The SIMATIC S7-1500 controller also has a modular design and can be scaled in terms of functionality, allowing you to perfectly adapt set-up and functions to your machine design. TIA Portal allows you to integrate all major components in your automation project: safety, security, HMI, drives, decentralised peripherals and now also Motion Control.

If you want to know exactly how the S7-1200 and S7-1500 differ from the S7-300 (and the S7-400), check out this comprehensive comparison.



If you decide to replace phased-out products, itsme can also assist you. Among other things, we offer support for migration, re-engineering and hardware conversion. Our wide range of Cedeo-accredited training courses facilitates the transition to an up-to-date installation and enables you to make optimal use of the many possibilities offered by TIA Portal. An overview of available S7-1200/1500 training courses can be found here.

For the sake of compatibility, the basic SIMATIC features have been retained. This means that the S7-300/ET 200M system families, which will only be available as spares for the next ten years, can easily be replaced by Siemens' new series.

    Siemens - SINAMICS G220 variable speed drive now also in IP55
    In addition to the previously released IP20 variant of the SINAMICS G220 variable speed drive, the IP55 version of this innovative drive is now also available. This version comes standard with coated circuit boards that make the inverter resistant even outside the control cabinet to aggressive influences in a harsh industrial environment. As an option, a housing-mounted isolating switch can also be supplied to ensure safe disconnection of voltage without any other external components.

    DigiFlow - Making Life Easier for Customers
    Technical services provider Breemes supplies customers with PLCs, drives and other materials. Customers like industrial automation company Digi-Flow. Turnover, both parties feel, is not the ultimate indicator of a good relationship. Coming up with solutions together and providing knowledge are equally important. Ultimately, Breemes has to make the customer’s life easier, Digi-Flow CEO Eric Decant believes. Antwerp-based Digi-Flow assists industrial companies in their transformation to smart industrial environments using industrial automation and digitalisation. The company is a spin-off from ESAS Automation in 2020. Solindus, now ESAS, had grown into a company with 2,000 employees after its founding in 2003 by Eric and Robert Decant. With Digi-Flow, they wanted to go back to small-scale entrepreneurship. Eric Decant is now the CEO of the company, which has 30-plus employees. ‘I’m still ambitious, but I don’t want to complete this kind of strenuous trajectory on such a large scale anymore.’ Meanwhile, he is grooming his son to take over the reins. This makes Digi-Flow a true family business, as reflected in its core values of co-creation, long-term vision, lifelong growth and personal.

    ATR Engineering - Short delivery times for components and decisions
    Being able to shift gears quickly is crucial to the success of industrial automation projects. This refers not only to the delivery of components but also to decision-making. Short lines of communication are important here. That was the case in the project to control a washing line for plastic PET flakes, in which ATR Engineering and itsme teamed up closely. ‘The added value of our collaboration is being able to anticipate customer requests extremely quickly.’ Bringing ten years of experience in industrial automation to the table, Adrie van Triest started his own company in 2019. With a broad approach, ATR Engineering in Berkel-Enschot focuses on hardware and software engineering. ‘Our area of expertise is offering total solutions for industrial automation centred around the design of PLC controls. We will sit down with a customer to discuss pending automation issues and we will determine the needs and wishes for a project together in advance. We also offer flexible support for projects or commissioning.’ ATR Engineering is a small company currently employing four engineers from different disciplines. There is also a permanent ‘flexible shell’ of engineers and technicians available to help during peak periods.

    Top Cold Control - Short lines for energy management and project collaboration
    Specialist in industrial refrigeration Top Cold Control carries out complete projects, and energy management cannot be missing from that these days. This starts with a lot of measuring. For a cold store in Amsterdam, itsme, in consultation with Top Cold Control and the customer, designed a solution to integrate energy measurement in the control system. Top Cold Control from Nieuwkuijk, specialised in industrial refrigeration technology, realises large projects for customers in the Netherlands, Belgium, Germany and, through them, elsewhere in the world. These include refrigeration and freezer systems for slaughterhouses, processing companies, cold stores and transport companies. Top Cold Control can handle all common refrigerants, but specialises in the use of the natural refrigerants ammonia (NH3) and carbon dioxide (CO2). For fast freezing, Top Cold Control supplies advanced, energy-efficient freezing tunnels. "The company stands out for its short lines of communication," says operations manager Arjan Maas. "We are always accessible and customers immediately get the right person on the line with us."
