Cycle Time Monitoring

This tabsheet can be reached by PLC|CPU Properties.

The cycle time monitoring reacts if the program needs more than 1 sec in real time. In most cases you have programmed an endless loop then. By default it is not activated because it is not impossible that it causes unsettled crashes occasionally. A changing of this operation is effective as soon as you restart TrySim.

If you have programmed an endless loop without an activated cycle time supervision and if you have also selected the option “start automatically” (View|Options|Machine), then you have got a problem: As soon as you start TrySim the PLC-programm is started and is in the endless loop.

Start TrySim with the option -n, that causes that no program will be started automatically anymore. If you do not know how to start a program in Windows with an option you have to enter in the DOS-window: \program\trysim\trysim -n. (provided, that you have installed Try Sim into the suggested directory, otherwise you have to adjust the path correspondingly).

P.S. The new cray is so fast that it can bring an endless loop to an end in less than 24 h. :-)
