hello friends, when i done a modelling in simulink error "the "FixedStepDiscrete" solver cannot be used to simulate block diagram,because it contains continuous states" is occuring.... even i tried all the solver types but nothing worked.. help me..

You mean "all the solver" that are available??
Choose "ode45" or "auto". What is the error message if theare are any? It can't be the same as "the FixedStepDiscrete cannot be used".

On the left of "solver", select "Variable-step" and then try different type of solver.
You may be abel to run simulation but won't be able to generate PLC code. To generate code, the solver type has to be "fixed-step". You need to make your model discrete. Right now, your model has continuous states as the error message says.
