2) FEEDBACK PACKET
▪ Structure
▪ Element
• Command codes define the purpose of a packet.
4. COMMAND (1Byte)
• Additional packet factor according to Command.
5. FACTOR
Verification data to check omission and any changes of packet data. The interaction formula will be:
•
Checksum = Binarylnvert (LOWER_BYTE (ID + SIZE + C FACTOR#1 + ... + FACTOR#N))
• LOWER_BYTE = Only the lower 1 byte is taken among the summed data values.
= Divide the summed data value by 0x100 and take only the remainder.
• Here is formula for above:
LOWER_BYTE (ID + SIZE + C FACTOR#1 + ... + FACTOR#N) == (ID + SIZE + C FACTOR#1
+ ... + FACTOR#N)% 0x100
After reception of Command Packet, the actuator sends Feedback Packets including the requested information. Its
structure is as shown below.
