Migration of a Siemens PLC from S5 to S7

Failure of PLC

Does your company have Programmable Logic Controller over 15 years old? If the answer is I.SI, your business is exposed to various dangers that can trigger costs and bring down productivity.

The main dangers faced by an obsolete PLC are:

• The outdated PLCs operate in isolation, without communication or integration into the information network, which makes them ineffective.
• Moreover, the threat of critical failures always comes up with an old-fashioned automaton.

The most common causes of these failures are:

• Loss of communication with the PLC due to overvoltages by atmospheric or transient discharges that can burn the PLC communication ports.
• It is becoming increasingly common for industrial networks to be highly contaminated by the proliferation of other devices (switching sources, induction furnaces, …) that create electromagnetic or radio frequency interferences.
• The memory of a PLC can be damaged by dust deposited on the plate, ambient humidity, temperature… or by the above-mentioned overlays and interferences.
• And finally, the most common failure in automatons are burnt ins and outs and damaged relays.

A discontinued PLC can become a big problem, as in the face of one of these failures we are more than likely to find that there are no spare parts in the market to repair it and that there is no technical service that serves its software.

The migration of old PLCs should not be considered an expense, but an investment for the future that is also key to making our facilities more competitive and effective.

Are your PLCs over 15 years old?

At CEFALUX we have the means and expertise to migrate your programmable automatons to the latest existing technology affecting as little as possible the day-to-day production.
