7 APPLICATION INSTRUCTION
7.21 Module access instruction
â– DTO(P)
• These instructions write the (n)  2 points of data in the device starting from the one specified by (s2) to the buffer memory
address specified by (s1) in intelligent function module specified by (U/H).
• When a constant is specified in (s2), (n) x 2 words of the same data (the value specified by (s2)) is written starting from the
specified buffer memory address.
• For the nibble of a bit device specified by (s2), specify K1 to K4 in the TO(P) instruction and K1 to K8 in the DTO(P)
instruction.
• When a number greater than 65535 is specified as the buffer memory specified by (s1), use the TOD(P) instruction or use
U\G in the MOV(P) instruction.
