The normal response is an echo of the request message.
Response message:
Function code 16 – Write Multiple Holding Registers
Function code 16 is used to write one or more holding registers in the actuator, referenced in Appendix A. When
the master accesses a register that is not supported by the slave it responds with an exception message.
The register address in this context is without ‘4xxxx’ identification, e.g. meaning address 0 equals register
40001.
Multiple registers are written as an entity with commands executed as the final stage. That means, if e.g. Holding
Register 1, 2 and 3 (Target Position, Command-Remote and Max Speed) are written in one single command then
the actuator will start running towards the new position with the new speed.
Broadcast is supported (but any response – including exceptions - is discarded).
Request message:
The normal response message returns the slave address, function code, starting address and the quantity of
registers written.
