Reading the user guide on program preview I saw this note, that really confuses me
NOTE 1 : The program preview is implemented using a software simulation of the scheduling algorithm:
● What you see accurately reflects how the programs are scheduled to run on the controller.
● All controller settings, such as Master zones, Sequential Mode , Station Delay Time , Master On / Off Time , are observed; and all station attributes such as Use Master Station , Activate Relay are also observed.
Why it says that use a sw simultation? For me is just show what is defined in the program, that actually is the first bullet above.
