CHANGE PROFIBUS ID FROM SDO:

The Change PROFIBUS ID from SDO is used to change the address of PROFIBUS (of the HD67551) using a CANopen SDO object. To use

for change the ID PROFIBUS, the SubIndex is fixed to 0.
The SDO is available in Read and Write mode.
In Read mode is possible to know the ID PROFIBUS saved in the Flash memory of the Converter and the current ID used by the HD67551.
The reading SDO return two bytes, in the first (MSB) the Address of PROFIBUS saved in flash memory is available, in the second byte
(LSB) the current Address of PROFIBUS is available.
For example if the SDO return the value 0x0706 that means:
07 is the ID PROFIBUS saved in the Flash Memory
06 is the current ID PROFIBUS of the converter
In Write mode is possible to set the PROFIBUS address and/or save in flash memory.
The SDO in write use two bytes. The first (MSB) is used to understand the operation to execute, in second (LSB) is used to write the new
ID PROFIBUS.
For example if write the value 0x0305 in the SDO that means:
03 is the operation to do with the new ID PROFIBUS
Bit 0 (LSB) means the new ID is saved in the Flash Memory
o
Bit 1 means the Convert reboot with the new ID
o
05 is the new ID PROFIBUS. Attention! The value for this field must be between 1 and 126.
