Use a 'Unit Delay' block. That is the counter. Add a number to it. The number is either 1 or -1.
Use S-R Flip-Flop block to generate the number. Its output is either 1 or 0 but you can multiple it by 2 and then minus 1 to get either 1 or -1.
Compare the counter value with 5 and 0 to get the Set and Reset signal for the S-R Flip-Flop block.

All blocks come from Simulink.
