SECTION 6
Program Execution Timing
The timing of various operations must be considered both when writing and debugging a program. The time required to
execute the program and perform other CPU operations is important, as is the timing of each signal coming into and leav-
ing the PC in order to achieve the desired control action at the right time. This section explains the cycle and shows how
to calculate the cycle time and I/O response times.
I/O response times in Link Systems are described in the individual System Manuals. These are listed at the end of Section
1 Introduction.
