4.4. SOE Communication Format Description
The function code of SOE inquiry is 55H and alarm SOE inquiry is 56H
which is the extension part of MODBUS RTU protocol. These function codes are
used to ask SOE in the nominated address and do not support broadcasting command.
The communication format is as follows:
