*1: Designated as "<Drive No.>:<File Name>". Example) 1:MAIN
*2: Local devices cannot be used.
Function
(1) The program stored in the memory card or standard ROM is transferred to the program
memory (drive 0).
If the transferred program is not registered to the program setting of the PLC parameter
dialog box, its program setting in the CPU module is set to the standby type.
At this time, the program setting of the PLC parameter dialog box does not change.
(To transfer a program with the PLOADP instruction, a continuous free space is required in
the program memory.)
(2) The program added using the PLOADP instruction is assigned the lowest number among
the unused program Nos.
(To assign a program number manually, store the program number to be assigned in
SD720.)
The following example assumes that "MAIN6" is added by the PLOADP instruction.
(a) When the program Nos. have been set consecutively, the new program is added at the
end of the preset program Nos.
When programs No. 1 to 5 have been set, the new program is added as program No. 6.
