APPENDIX A
A.2COMMAND EXECUTION
Commands are executed in two steps: selection and confirmation. First, send the command or operation selection
command. When the relay response arrives, send the confirmation. It is necessary to send the relay password. The
structure for both commands is the same; the only variation is the related code.
®
The ModBus function used is 16 (10h), PRESET MULTIPLE SETPOINTS. There must be an address where to write the
corresponding operation code. This address is 0 (0000H) for every operation. The data to be written must be in Intel
format; this means that the order of the bytes must be inverted (from lower weight to higher weight). The only exceptions
for this rule are texts, which are in reading order (Motorola format). In each case, the order is specified.
The available commands list is as follows:
