deleted from the program memory, and at the same time, the program stored in the memory
card or standard ROM designated by is transferred to the program memory and placed in
standby status.
(When the program is transferred to the program memory, the program must have a
continuous free space.)
The program set as the "scan execution type" with the PSCAN instruction or the program set
as the "low speed execution type" with the PLOW instruction cannot be deleted.
(2) The program to be transferred to the program memory by the PSWAPP instruction will have
the program No. of the program to be deleted from the program memory.
(If there is an open program No. before the program to be deleted from the program
memory, the program to be transferred to the program memory will not have the open
program No.)
When program No. 2 is "Empty", the program transferred to the program memory is
registered as program No. 3 by the program swapping of program No. 3 with this instruction.
