In October 2023, the S7-315 CPU was discontinued by Siemens. Anyone who then carried out a retrofit with an S7-1200 or 1500 had to expect waiting times and also had to tell their end customers that they could say goodbye to their trusted Siemens SimaticManager and buy the Siemens TIA Portal. The reactions to this are likely to be mixed. INSEVIS CPUs were able to remedy this, because they are compatible with the S7-315-2PNDP in terms of language and enable retrofit projects to be continued in the long term. But the extremely fast INSEVIS panels are also increasingly in demand; economical, robust and with an operating system that is available in the long term. That is why Jung & Debus Industrieservice from Haiger has been using INSEVIS products with great satisfaction for several years to maintain older machines for various customers. Reliable, punctual and of high quality. This is what customers have come to appreciate about Jung & Debus Industrieservice and brings them long-term satisfied customers and new orders.
