Processing details
■
FROM(P)
• These instructions read (n) words of data from the buffer memory specified by (s) in intelligent function module specified by
(U/H), and store the data to the device specified by (d) and later.
■
DFROM(P)
• These instructions read the (n)
2 words of data from the buffer memory specified by (s) in intelligent function module
specified by (U/H), and store the data to the device specified by (d) and later.
Precautions
• For the nibble of a bit device specified by (d), specify K1 to K4 in the FROM(P) instruction and K1 to K8 in the DFROM(P)
instruction.
• When a number greater than 65535 is specified as the buffer memory specified by (s), use the FROMD(P) instruction or
use U
\G
in the MOV(P) instruction. The following shows the program to transfer the buffer memory #70000 in the
intelligent function module No. 1 to D0.
