10.8.3.3 Read block parameters
Task:
The firmware version (code C00099) is to be read from the parameter set of the
controller with node address "12". The firmware version has a length of 11 ASCII characters
which are transmitted as a block parameter. Depending on the block, the data width from
the 2nd to 8th byte is assigned within the user data.
Telegram 1 to the drive: Read request
Response telegram 1 from the drive: Indication of the block length (11 characters)
Identifier User data
1st byte 2nd byte 3rd byte 4th byte 5th byte 6th byte 7th byte 8th byte

Explanations on the telegram to the drive
Identifier = 1536 + node address = 1536 + 12 = 1548 = 0x060C
(1536 = SDO1 basic identifier to the controller)
Command = 0x40 = "Read request" (read request of a parameter from the controller)
Index = 24575 - code number = 24575 - 99 = 24476 = 0x5F9C
Subindex = 0 (code C00099
does not have any subcodes)

Explanations on the telegram from the drive
Identifier = 1408 + node address = 1408 + 12 = 1420 = 0x058C
(1408 = SDO1 basic identifier from the controller)
Command = 0x41 = "Read response" (response is block telegram)
Index as in telegram to the drive
Subindex
Data 1 ... 4 = 0x0000000B = data length of 11 characters in the ASCII format
