An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is
stored in D8067.
• When the last device number to be transferred exceeds “32767” (error code: K6706)
At this time, devices up to the last one (R32767) are read and transferred.
• When a memory cassette is not connected (error code: K6771)
Program example
In the program example shown below, the contents (current value) of 4000 extension file registers ER1 to
ER4000 inside the memory cassette are read, and transferred to 4000 extension registers R1 to R4000 inside
the built-in RAM.
