I'm trying to bring some e-stops into ignition for monitoring from a CompactLogix 5069-L320ER ver 33.12 PLC, and in the PLC is listed as a Bool256. When I try to to add this in, I notice that its only listing 8 items that can then be expanded from 0-31. Am I correct in my assumption that bool256[0].0-31 are equivalent to 0-31 and then bool[256].0-31 would be 32-64 and so on? I've attached screenshots to make it more clear.

Yes, that's right. Bool arrays don't actually exist in the controller - it's actually as many DINTs as needed for the size of the array.

Thanks for that quick reply and glad I was right on this one. Just wanted to double check before I went too far. Amusingly, I don't think any of these past... INP\_EmergencyStop[20] are actually being used.
