FROM(P),DFRO(P)
9.2.1 Reading from Other CPU Shared Memory (FROM(P),
DFRO(P))
FROM(P),DFRO(P)
(1) When Basic model QCPU, Universal model QCPU is used
*3: The setting range varies depending on the auto refresh setting range of the multiple CPU high speed
communication function.
Function
FROM
(1) Reads the data of n3 words from the CPU shared memory address designated by n2 of the
CPU module designated by n1, and stores that data into the area starting from the device
designated by .
Basic model QCPU:The first 5 digits of serial No is "04122" or higher.
High performance model QCPU:Function version B or later.
n1 : Head I/O number of the reading target CPU module (BIN 16 bits)
• Basic model QCPU : 3E0
H to 3E2H
• Universal model QCPU: 3E0H to 3E3H
n2 : Head address of data to be read (BIN 16 bits)
• Basic model QCPU : 0 to 512
• Universal model QCPU: 0 to 4095, 10000 to 24335*
3
: Head number of the devices where the read data is stored (BIN 16 bits)
n3 : Number of read data (BIN 16 bits)
• Basic model QCPU : FROM(P): 1 to 512, DFRO(P) : 1 to 256
• Universal model QCPU: FROM(P): 1 to 14336*
