Pointer setting
The following menu item is to set pointers.
[CPU Parameter] [Memory/Device Setting] [Pointer Setting]
*1 Up to the number of "Total points of pointer device area" - "Number of points of global pointer".
*2 The default number of points is 32768 for the R120CPU, R120ENCPU, R120PCPU, R120PSFCPU, and R120SFCPU.
*3 The default number of points is 8192 for the R120CPU, R120ENCPU, R120PCPU, R120PSFCPU, and R120SFCPU.
*4 The default number of points is 16384 for the R120CPU, R120ENCPU, R120PCPU, R120PSFCPU, and R120SFCPU.
Specify a pointer number which is equal to or lower than "(end number of the pointer range specified in the
parameter) - (number of points of the global pointers)".
21.13 Interrupt Pointer (I)
This device is used as a label located at the head of the interrupt program. This pointer can be used in all the programs being
executed.
Setting the execution type of program to the event execution type eliminates the need to write (I) the
interrupt pointer. ( Page 59 Interrupt occurrence by the interrupt pointer (I))
