(b) CPU shared memory address of the Universal model QCPU
*3
*2:
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.
*3:
With the following CPU modules, data cannot be read from the multiple CPU high speed transmission area.
•Q00UCPU
•Q01UCPU
•Q02UCPU
(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.
DFRO
(1) Reads the data of (n3
×
2) 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 .
(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.
Read of data from the CPU shared memory can also be performed using the intelligent function module devices.
For intelligent function module device, refer to the QnUCPU User's Manual (Function Explanation, Program Fundamentals)
or Qn(H)/QnPH/QnPRHCPU User's Manual (Function Explanation, Program Fundamentals).
