1) Overhead time when local devices in the interrupt program are enabled
When SM777 (Enable/disable local device in interrupt program) is turned on, the time given in Table10.6 and
Table10.7 will be added to the overhead time given in Table10.3 and Table10.4.
Each n, N1, N2, and N3 in the table indicates the following:
• n: Number of local device points (unit: K words)
• N1: Number of devices that specified a local device
• N2: Number of word device points that specified a local device
N3: Number of bit device points that specified a local device
