Hi Everyone
I have a problem with my simulink design. I am creating a simple Bus signal with Bus creator ( picture 1)and giving a name as "LettersBus", then I want to delay my signal by using Memory block with initial condition "LettersBus" and checked inherit sample time (picture 2) . When I put a Bus selector after Memory Block , Bus selector doesn't see any signal of my Bus creator (picture 3). I couldn't understand why. Additionally, I have two errors when I run the simulation(picture 4). I don't know why it is giving DatatypeStr error all my constant blocks are Inherit from Constant value type and sample times 0.005.
When I don't use initial condition for Memory Block it shows bus signals after, but I want to use it with initial condition Lettersbus.
Matlab2015a .
Could you please help me? It seems simple but I couldn't find the way out. Helps would be much appriciated.

"LettersBus" here is just a signal label, or the name of the bus. You can't assign it as the initial condition of the Memory block. Try 0:4 or any other valid value as the initial condition.

Thanks for the answer, but what is the effect of 0:4 for initial condition ? When I write so, would that let those 5 signals from the bus creator pass through as they are or it will give those 5 signals initial conditions as 0 1 2 3 4 and then delay them ?
