_Reason for the change:_                                                    


The above digital I/O modules of the S5-135/155U PLCs have had              

to be redesigned because the supply of some electronic components           

has been discontinued. The modules have been given new Catalog              

Nos. but are fully compatible with the previous modules. The                

prices have also not changed.
