Event packet consists of 3 blocks as shown above.

1. Block 0.




2. Block 1.

3. Block 2.

1.1.i. BLOCK 0: The size of the BLOCK 0 is 11 bytes. The structure of Block 0 is

common for any type of event packet and it is having the following five fields.

START: AAH and 66H are the start of the event packet. Here the Header second byte

is changed to 66 H from 55 h, and acknowledgement header second byte is changed to

99 H from 33 h. To identify the old units connected to this data logger and also to

provide the backward compatibility [To support data logger common protocol].

ID NO: This is used for the identification of various devices like FEP,

DATALOGGER and RTU etc.

Serial Number: It is the sequence number of packet. With this CMU will identify that

it is receiving all the packets or not. Serial no will start from 0000H, whenever a

packet is created count will be incremented by one, and will roll over to 0000H after

reaching FFFFH.

PACKED TIME:

Time will be stored in the Packed Form. This is a long word size and time will be

calculated in multiples of 1/64 second. This long word will hold time for one year. The

equation to build packed time from the real time is given below.

FIELD NAME SIZE IN BYTES START 2 ID NO 2 SERL NO 2 PACKED TIME 4 PACKED YEAR LSB 1




Packed time = (Days x 24 x 60 x 60 x 64) + (Hr x 60 x 60 x 64)+(Mt x 60 x 64) + (Sec

x 64). Here Days = Number of completed days till present date

Hr = Hours

Mt = Minutes

Sec = Seconds

PACKED YEAR LSB: It will represent the YEAR LSB of the packet in which year

it was created. Here year LSB means in 2012 year 12 will be the LSB and it will be

stored as 0C H.
