'''Number of Data 2''' – a number which defines how many records are in the packet. This number must be the same as “Number of Data 1”. <br>
'''Number of Data 2''' – a number which defines how many records are in the packet. This number must be the same as “Number of Data 1”. <br>
'''CRC-16''' – calculated from Codec ID to the Second Number of Data. CRC (Cyclic Redundancy Check) is an error-detecting code using for detect accidental changes to RAW data. For calculation we are using [[Codec#CRC-16|CRC-16/IBM]].<br> <br>

'''Note:''' for [[FMB630]], [[FMB640]] and [[FM6300|FM63XY]], minimum AVL record size is 45 bytes (all IO elements disabled). Maximum AVL record size is 255 bytes. Maximum AVL packet size is 512 bytes. For other devices, the minimum AVL record size is 45 bytes (all IO elements disabled). Maximum AVL packet size is 1280 bytes. <br>

Codec16 is using for FMB630/FM63XY devices. This protocol looks familiar like Codec8 but they have some differences. Main differences between are shown in table below:
