10.2.2 CIF Multi SDO read access

With the multi SDO read access command, up to 8 SDO read accesses can be made within one command.
The maximum data length for each access is 8 bytes.
At first write the node number (0, 1-127), the Object Dictionary Index and the Sub index to the BFMs. Finally
the command code for multi SDO read access "8" must be written to BFM #1000 in order to trigger the
command execution.
If the access has been successful, BFM #1000 will display "9" and BFM #1001 to #1064 will contain the node
number, index and sub index for verification purposes.
BFM No.
