OperandsOperands Settings RemarkS1Specify the starting number of the area (2 words) that stores control data.S1Specify the transfer method.Word transfer: Specify the number of send words.Bit transfer: Specify the bit number of a master unit and that of adestination unit.(Note 1)(Note 4)S1+1 Specify the COM port No of a master unit and the unit number of adestination unit.(Note 2)(Note 3)S2 Specification ofa master unit Specify the area of a master unit that stores send data. (Note 4)D Specification ofa destination unitSpecify the area type of a destination unit that stores senddata. The number is specified at 0. (Note 5)n Specification ofa destination unitSpecify the starting address of a destination unit thatstores send data.(Note 5)(Note 6)(Note 1): To [S1], the following specification should be applied. The specification method differs depending on wordtransfer and bit transfer.[S1]：Transfer inword unitsSpecify the number of send wordsH001 to H07F (1 to 127 words)H0[S1]：Transfer inbit unitsDestination bit No.(H0 to HF)H8 H0 (fixed)Master unit bit No.(H0 to HF)(Note 2): To [S1+1], the following specification should be applied. When the COM port No. is 0, specify HF for thehighest digit.[S1+1]：Select a COM port（H1/H2/HF）Unit No. (H00 to H63)(0 to 99)H0 (fixed)(Note 3): When “0” is specified for the destination unit number, global transfer is applied. In this process, there is noresponse message from a destination unit.
