What are the reasons driving our customers to modernize their dated systems? This article was written several years ago but is still true. https://blog.se.com/machine-and-process-management/2013/05/08/is-it-always-true-if-it-aint-broke-don...
Please share your thoughts. Any questions on modernizing legacy PLC systems?
Problem modernizing (PLC) systems is the funding. When a modernized system is acting the same way as it did before, it's hard to get budget for this.
Main arguments not to modernize are: " it is still functioning, we had any issue in years, we have a lot of spare parts".
My experience finding the best possible arguments to modernize are:
- Cybersecurity. Company's who have to comply to cyber security standards and solutions:
- Old software (Concept, Modsoft, ProWorX, X-Tel) is not supported on latest Microsoft platforms, Windows-XP and even older systems are not allowed by the IT department
- Old (hardware) platforms do not comply to cyber security standards
Interruption of production due to a cyber security issue, will cost a lot of money and reputation.
Today, cyber security is becoming even more important as pandemic issues ask for (more) remote monitoring, diagnostic and remote maintenance, which also implies the need for secured remote access.
But always keep your eyes and ears open for other arguments, as customer demands will differ.
In most cases maintenance think about modernisation when installed PLCs are becoming out of service and there no possibility to repair machine anymore in case of failure.
And the biggest problem in this term is the PLC program, who designed it, who will be the designer for the new platform and how to transfer the existing one to the new platform without failure or minimize failure risk,
