Hi
First of all taje a look at Where and when do you need peripheral addressing? in your case the major thing you should be aware is IO accesss time which will be more longer if yoy switch from pripheral addressing to IO address area( of work memory).if this is not matter then you can use the features of PI addressing specially data cinsistency ,data availability even in real hw failures,data reliabilty in case of failures(defining failsafe substitutes),manipulating IO(force/simulate). If time is matter then you can use process image partion instead of using OB1 process image. Hope this helps regards |
