Hi All:

I am using Simulink, In which I need to count Up and Down depending upon the input values.

Can anyone help me out that is their any way to internallay switch the counter from counting Up to Down or from Down to Up. Or is heir any way to provide the Initial value to the counter from out side the counter block.

If not possible then what should be the ulternate to such sort of problem.

I would suggest using either an integrator block with external initial conditions and a switched input, or design a Stateflow block to do this by having a 'CountUp' and a 'CountDown' state.
