How can I implement redundant IO with M580 ?

I just gone through the TVDA document of the caption subject and would like to drill in more details for a tender proposal. Hope someone can share their experience on this implementation.

1. For Digital Input and Output, can we use BMXDDI1602/DDO1602 instead of BMXDDI3202K/DDO3202K, that would be more flexible.

2. For Analog Input and Output, please share more detail on the JM Concept as their information is very limited. Does each analog module require one set of (TELIS900+BL10TRV) or (GK300D1+BL10GRV)? Seems the interconnection cable is missing on the BOM !!!

Thanks in advance.

1. yes. you can use DDI1602/DDO1602 but you must install connection manually (paralleling the input/output) instead of using ABE7 kit

2. no Idea.
