(Note 5) WX,WY,WR,WL,DT,LD,U,H(For registertransmission)W mode: 1 to 56W2 mode: 1 to 1020(For bit transmission)1 (Fixed)D1 Specify the device starting address in the homeunit storing received data. (Note 1)WX,WY,WR,WL,DT,LDX,Y,R,L,DT.n,LD.n (Note 1)D2 Specify the device area of the local unit storingthe execution result code (1 word). WX,WY,WR,WL,DT,LD -(Note 1): The transfer method varies according to the device type specified for operands [S2] and [D1].Device specified in [S2] and [D1] Transfer method16-bit device: WX, WY, WR, WL, DT, LD Register transmission1-bit device: X, Y, R, L, DT.n, LD.n Bit transmission(Note 2): The bit devices DT, n, LD and n cannot be specified for the starting address of the source data ofdestination unit.(Note 3): When the source unit is FP7, only global devices can be specified. Local devices cannot be specified.(Note 4): When the source data is FL, specify the integer (U, H). (For FL100, specify U100.)(Note 5) The number of sent data is in word unit for the register transmission and it is in bit unit for the bittransmission.
