In this lesson we are going to discuss two functions that may be accessible in the property selections of your CPU. Those functions are test mode and process mode. These functions allow you to test your program in different modes. The default mode, which is test mode, allows you to test your program without restriction. However, process mode applies a maximum cycle time restriction which prevents the CPU from going to stop mode when the cycle time exceeds the set maximum. Lets’ open this lesson and see the difference between these two testing modes.
