How to solve the the parameter 'SampleTime' must be a real double scalar (period) or a real double vector of length 2 (period, offset).

the parameter 'SampleTime' must be a real double scalar (period) or a real double vector of length 2 (period, offset); where period, offset must be finite and non-negative and offset must be less than period.

The sample time of the block is not properly set. What is your current setting? Show the block

The sample Time Ts=0.01. And i stored all data in data dictionary. @Fangjun Jiang

[Fangjun Jiang]

Does the error occure at this block? Do Ctrl+d or start simulation, let Simulink point to the block. Make sure Ts is taking value from SLDD, not from base workspace or model workspace.

[Baari Akshay kumar]

The error occuring from the block and the Ts value is also from SLDD. After this also the errors are occuring. Can you please solve the error.

Thank You. @Fangjun Jiang

Where are you creating Ts ? It sounds like you might be putting it in a Data Dictionary ? How have you configured Ts there? It should probably be a Simulink.Parameter object

This is Ts i stored in SLDD.

[Baari Akshay kumar]

But i need all values in single data type.

[Fangjun Jiang]

In the block dialog, type in 'double(Ts)', instead of 'Ts'.

I still came across this problem, Anyone knows how to fix it?

[Fangjun Jiang]

In this particular case, class(Ts) being 'single' was the root cause. The solution was to specify the sample time as 'double(Ts)'.

Answer 1

[Fangjun Jiang]

This is the cause and it shocked me.

The "Ts" is currently of data type "single". Change it to be "double".

Answer 2

[Walter Roberson]

specify double(Ts) as the Sample Time in the block?
