1-3 Section Structure and Operation 15 1-3-4 PC Operation at Startup The time required for startup initialization depends on several factors, such as the operating conditions (including power supply voltage, system configuration, and ambient temperature) and the program contents.
1-3 Section Structure and Operation 16 1-3-5 Cyclic Operation and Interrupts Initialization processing is performed when the power is turned on. If there are no initialization errors, the overseeing processes, program execution, I/O refresh- ing, and communications port servicing are performed repeatedly (cyclically).
1-3 Section Structure and Operation 17 Th e cycle time will vary slightly depending on the processing being performed in each cycle, so the calculated cycle time will not always match the actual cycle time. The following diagram shows the cyclic operation of the CPM2B when the pro- gram is being executed normally .
! 1-3 Section Structure and Operation 18 When a n interrupt is generated during execution of the main program, main pro- gram execution is interrupted immediately and the interrupt program is execut- ed. The following diagram shows the cyclic operation of the CPM2B when an interrupt program is executed.
