■Description, data type of result
Processing details
• (n) words of data are read from the address specified with (S2) of the buffer memory in the module specified with (S1), and
are stored since the device specified with (S2).
Writing device data can be performed with the module access device (U\G).
(Example)
Reading 1 word of data from buffer memory address 10H of intelligent function module (start I/O number:
020H), and storing in W0.
