Table 6-4 Slave response
FC16 Write multiple
Writes a contiguous array of registers. The slave imposes an upper limit
on the number of registers which can be written. If this is exceeded the
slave will discard the request and the master will time out.
Table 6-5 Master request
Table 6-6 Slave response
FC23 Read/Write multiple
Writes and reads two contiguous arrays of registers. The slave imposes
an upper limit on the number of registers which can be written. If this is
exceeded the slave will discard the request and the master will time out.
Table 6-7 Master request
Table 6-8 Slave response
6.2.7 Extended data types
Standard MODBUS registers are 16bit and the standard mapping maps
a single #X.Y parameter to a single MODBUS register. To support 32bit
data types (integer and float) the MODBUS multiple read and write
services are used to transfer a contiguous array of 16bit registers.
Slave devices typically contain a mixed set of 16bit and 32bit registers.
To permit the master to select the desired 16bit or 32bit access the top
two bits of the register address are used to indicate the selected data
type.
The selection is applied for the whole block access.
