Modernising plants without having to shut them down

A newly developed compact system allows plants to be modernised by replacing their S5 controls with S7 controls. This upgrade is even possible without the need to shut production down. Which doesn’t only help reduce costs, it also makes them calculable, which wasn’t previously the case because the otherwise neces-sary production downtimes made it difficult to accurately budget for the incurred costs.

In the past it was previously nec-essary to replace the entire sys-tem when S5 automation equip-ment needed modernising. This meant that companies were forced to shut down production, which in turn would result in costs that were difficult to calculate beforehand. That’s why ABC IT GmbH created the ABC X-CPU-2 m57, a central component group that significantly simplifies retrofit-ting.

 

It does not only allow the Siemens Step5 (S5) and Step7 (S7) systems to be used for programming the new CPU, they can be both used simulta-neously. But the best thing about the new system is that it allows individual components to be replaced separately. Which makes partial upgrades feasible and thus helps reduce costs. Something that many businesses might consider because the full switch to S7 doesn’t deliver any additional benefits.

 

The X-CPU-2 allows plants to be modern-ised by replacing only specific components (Fig. 1). Thus making it possible for companies to precisely calculate the costs for the individual modernization and conversion phases. This was previously difficult because the necessary downtimes and expensive and complex procurement of spare parts meant that it was difficult to stay within pro-jected budgets, particularly as the work often didn’t result in a full conversion from S5 to S7. A fact that has also often meant that the switch did not deliver any particular benefits to users as it generally didn’t result in any improvement to plant productivity. Intelligent modernisation, on the other hand, only makes changes in those areas where they are actually needed. The money thus saved may then be spent on the maintenance and development of production.
