8.26 Module Access Instruction
Reading 1-word/2-word data from another module
FROMD(P), DFROMD(P)
• FROMD(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.
• DFROMD(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.
