Let’s say you have been using a product for almost 15 years. This is not to say that the program will suddenly fail, that’s an entirely different theory and depends entirely on how the programmer has written the code.PLC code, once written, operates in the same way for the rest of its life.

The problem starts with the hardware and support. If a PC manufacturer’s product is unstable or has a lot of limitations in programming, it tends to stay in production for a long time.

The sooner PLCs start to become obsolete, the fewer their replacements will be. Even the system integrator or the PLC manufacturer itself will not be able to provide technical support because the personnel will be transferred to a new brand or their programming cables will no longer be available.

In this case, if the PC system suddenly fails for some reason, you have no choice but to wait for a longer downtime. In addition, if you were able to obtain this PLC elsewhere, the cost would be prohibitively high and out of budget.

Due to the current supply chain disruptions and the recent lack of new industrial automation solutions and components, it is impossible to accurately estimate how long it will take to produce a new machine. In this case, you will have two choices: either migrate to another brand or upgrade your existing version to a newer firmware CPU or program.

Migration and upgrades therefore play an important role in industrial automation. In addition, new solutions bring more new features.
