Command 15 (Y, R multi−points write) send
Example) When the 64−bit data from the bit 0 of the WR3 to the bit F of the WR6 is transmitted to the W0 to
Y3F of the unit No. 7 in the remote unit from the COM1.

*Specify the coil No. of the destination for the starting
No. of status change. (Remote unit)
The quantity of changed coils is that the No. of write
bits is changed to HEX.
Max. quantity of changed coils is 2032 (07F0H).
(due to the restrictions on the MODBUS protocol)
No. of data (No. of bytes) is calculated regarded 8 coils
as 1 data (1 byte). (Max. 254 (FEH) bytes)
