16 (0x10) Write multiple registers
On slave holding registers, data is changed by the specified number from the specified address.
If broadcast (0) is specified, all slave holding registers of the same address are rewritten.
To request, specify the register address and the number of registers and data to change.
The slave transmits the contents of one register as expanded in double bytes.
* N = Number of registers
Example 1) Change the weighing function 2 (address 40047) to 111 (0x006F) and digital
low pass filter to 5Hz (*) in the 16-bit wide integer data area.
* Select the F701-P digital low pass filter setting from:
0: 1.5Hz, 1: 2Hz, 2: 2.5Hz, 3: 3Hz, 4: 4Hz, 5: 5Hz.
Write "5" for 5Hz in the example.
Keep in mind that the relative address for writing in weighing function 2 is 0x2E.
