Simulation repetition rate

In TrySim there is a virtual time with the resolution of 1 milli second.

Here you can adjust how many virtual milli seconds passes by between two simulation steps of the machine.

In reality this point nearly corresponds to the cycle time of the PLC.

The smaller you set this number the more exact is the simulation. But the maximum quick motion factor decreases by this in big machines.

The simulation rate will not be changed by the menu points Machine|Faster / Slower. By this just the speed of the virtual clock will be influenced.

CPU-Overspeed

With this you can adjust how often the OB 1 shall be executed between two machine-simulation-steps. In generell it is not useful to let the OB 1 run between two simulation steps several times because the inputs will always have the same value and the outputs will not be analysed, but in a single case it is possible that it makes sense.

Graphic refresh rate

Here can you adjust, how often the graphics are refreshed.

The drawing costs lots of time although the graphic of TrySim is quite simple. If you have programmed big projects and if you attach importance to a wide quick motion range, you should adjust a relatively slow graphic refresh rate. If small projects with fluent movements shall be represented the graphic repetition rate needs to be adjusted as small as possible.

Which adjustment is optimal depends on the speed of your computer and the size of your machine. But a graphic refresh rate which is adjusted too small does not matter in generell, because TrySim draws less automatically if it is overloaded because of a simulation speed which is too fast.
