8 APPLICATION INSTRUCTION
8.26 Module Access Instruction
Reading 1-word/2-word data from another module
FROM(P), DFROM(P)
• 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 (d).
• DFROM(P)
These instructions read the (n)
2 words of data from the buffer memory specified by (s) intelligent function module specified
by (U/H), and store the data to the device specified by (d) and later.
Setting data
■
Descriptions, ranges, and data types
*1 In the case of the ST language and the FBD/LD language, U/H displays as UnHn.
■
Applicable devices
*1 Only the DFROM(P) instruction can be used.
