Task:
The heatsink temperature (43 °C) of the controller with the node address "5" is to be
read (code C00061, data format INTEGER32, scaling factor 1).
Telegram to the drive
Response telegram from the drive (for successful execution)

Identifier = 1536 + node address = 1536 + 5 = 1541 = 0x0605
(1536 = basic identifier of SDO1 to the controller)
Command = 0x40 = "read request" (request to read a parameter from the controller)
Index = 24575 - code number = 24575 - 61 = 24514 = 0x5FC2
Subindex = 0 (code C00061 has no subcodes)

Identifier = 1408 + node address = 1408 + 5 = 1413 = 0x0585
(1408 = basic identifier of SDO1 from the controller)
Command = 0x43 = "read response" (response to the read request with the current value)
Index Same as for telegram to the drive
Subindex
Data 1 ... 4 = 0x0000002B = 43 [°C]
