What does the setting 'Initialize %MWi on cold start' have on M580 Safety PLCs?

Published date: 27 August 2019

Issue
Looking to understand the impact of this setting with the M580 Safety Controllers.

Product line
Unity Pro XLS, Control Expert

Resolution
If %MWi is checked, on 'Cold Start' the located variables will be 'initialized' to what ever value is in the value column of the variable. 
If %MWi is unchecked, on 'Cold Stat' the located variables are ignored, if there is a value there already, it will remain as is.

*** The unlocated variables do not react to this setting, they always 'initialize' on 'Cold Start'. ***
