Hello,

My company owns a old automateS5-95U and I wanted to know what is the MTBF(MeanTime Between Failure)for this kind of product. What is the medium length of life of an S5-95U. I want to know if I must change it or if it can wait.

If you have any document or information to lead me I would be thankful.

Thank you for your link but I already took a look, there is no MTBF for S5 . My automate is also pretty old but unlike you, my company doesnt take care of it and this why I want to know what is the average life time of this kind of poduct to know when we should change it. Because if it fails, we would have to stop the production during 2 weeks at least I think.

Are not you afraid about your own automate?

Anyway thank you for your answer .

I want to know if I must change it or if it can wait.

The supply of SIMATIC S5 products will be discontinued in long steps. To provide our customers with accurate data for their planning, we have devised the following schedule:

• The mini PLCs S5-90U, S5-95U/F, S5-100U will be declared mature products as per 1.10.2003 .
• The affected products will then be removed from the catalog and the Mall, but will remain available on a regular basis for one more year, i.e. until 30.9.2004.
• The S5-115U system will be declared a mature product as per 1.10.2004
• The large S5-135/155U systems will be declared mature products as per 1.10.2005
• One year later each product will then reach spare part status and remain available in this form for 9 more years.

Regards,

Marcjan
