Command 16 (Multi−point register preset) send
Example) When the 3−word data from DT3 to DT5 is transmitted to the address H7788 of the unit No. 7 from
the COM1 port.

[S1] : H1607
[S2] : DT3 ( DT3=0011H

DT5=4455H)
[D] : H7788
[N] : K3
* When specifying multiple points by [N], the command is
automatically corrected.
* Max. quantity of write registers is 127 (7FH).
(due to the restrictions on the MODBUS protocol)
No. of data (No. of bytes) is calculated regarded No. of
write registers as 2 bytes. (Max. 254 (FEH) bytes)

Flag conditions
Σ Error flag (R9007) :
Σ Error flag (R9008) :
− Turns on when the control data of [S1] is a value outside of the specified
range.
− Turns on when the MODBUS mode has not been specified for the COM
port of the control data specified by [S1].
− Turns on when the number of transmission data is 0.
− Turns on when the number of transmission data is negative.
− Turns on when the number of transmission data [N] exceeds the operation
memory area specified by [S2].
− Turns on when the number of transmission data [N] exceeds the limit of the
MODBUS specifications.
