PLOADP

Load Program from Memory Card (PLOADP)

PLOADP

*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.

  : Drive No. storing the program to be loaded, character string data of the file name, or head number of the 

devices storing the character string data  (BIN 16 bits) 

*1

 

: Device that turns ON for 1 scan by the instruction completion (bits)
