I'd like to have some information about TMR (triple module redundancy) and QMR (quad module redundancy). for example how we can configure TMR in SIEMENS S7. in following how we can solve connection of analog modules in this architecture?

thnx in advance.

 

I've been told by Siemens they have no TMR, let alone QMR.

 

Siemens market the Moore TMR (or dual-not sure) in the name of Quadlog and you can have a look at the link http://www.sea.siemens.com/process/product/paqarch.html
If you want a true TMR have a look at http://www.icstriplex.com
