You can let run the virtual time of the simulated machine slowlier or faster. By this you can analyse critical moments calmly while you can let processes which already run correctly pass quickly. The precision of the simulation is not influenced by the slow motion or by quick motion, the simulation repetition rate keeps always to the value which is adjusted in View | Options | Simulation.
You can also get the quick motion by clicking (several times) on the rabbit 
.
Please understand the term/name “1: 100” as “As fast as possible”. TrySim itself cannot let even simple machines run with 50 times the speed ( by a simulation rate of 100 milli sec) not even on fast computers.
You can also change the simulation speed with Speed-Trigger automatically.
