Reading Data from the Automatic Update Buffer

G(P).RIFR
RnPCPU RnPCPU
RnCPU RnENCPU
(Process) (Redundant)
These instructions read data from the automatic update buffer or random access buffer. The instructions can be used for
communications with a module having the automatic update buffer such as AJ65BT-R2N.

Operand Description
(U) Start I/O number (first three digits in four-digit
hexadecimal representation) of a module
(s1) If data is read from an automatic update buffer: Station
number of intelligent device station
If data is read from a random access buffer: Specifies
the random access buffer.
(s2) Offset value from the start of the automatic update or
random access buffer that has been assigned to the
target station
(d) Start device for storing the read data
(n) Number of read points
