Return -(RET) or BEC, siemens

if i used a conditional RETURN -(RET) [or BEC (Block End Conditional)] at the start of an FB, and the RLO of the RET network is ONE.
1. are the outputs of the FB will be turned into Zeros.
2. or they are just going to keep the previous cycle values.

my condolences to Mr.Ron's family. he gave me knowledge which i respect a lot.

2.

thank u. that makes more sense ...
