19.5 Reading Data from the Automatic Update Buffer
G(P).RIFR
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.
■Execution condition
Setting data
■Description, range, data type
*1 Value that was set in the CC-Link configuration window of the engineering tool.
*2 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
