(2) When High Performance model QCPU, Process CPU is used
Function
(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 .
CPU shared memory address of the High Performance model QCPU and Process CPU
*1 : Usable as a user free area when auto refresh setting is not made.
When auto refresh setting is made, the auto refresh send range and later are usable as a user
free area.
(2) When 0 is specified in n3 as the number of data to be read, no processing is performed.
(3) The number of data to be read changes depending on the target CPU module.
n1 : Head I/O number of the reading target CPU module (BIN 16 bits)
n2 : Head address of data to be read (BIN 16 bits)
: Head number of the devices where the read data is stored (BIN 16 bits)
n3 : Number of read data (BIN 16 bits)
