Example) Switch the hold/judge ON (address 00001) to digital zero reset (address 00004)
ON/OFF.
Keep in mind that the relative address for writing in the hold/judge ON is 0x00.
The example shows rewriting of the F331 ON (1)/OFF (0) as follows:
Fill unused bits with "0".
* To judge coil execution, judge as complete with a normal response.
* Due to the nature of the commands, simultaneous execution in combination with the
following addresses should be avoided.
In this case, sequential execution results but correct operation may not be performed.
- Addresses 00001 and 00002
- Addresses 00003 and 00004
- Addresses from 00005 to 00007
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
