Protected Write
The Protected Write function writes 16-bit values into the I/O database of the slave device.
Access to the I/O database is limited to the protected address range of the slave device. The
data may come from any area of the master I/O database within its unprotected address
range.
Any number of 16-bit registers may be written up to the maximum number supported by the
slave device or the maximum number above, which ever is less. The write may start at any
16-bit register, provided the entire block is within the protected address range of the slave
device.
