ANALYSIS OF EVENT LOG DATA READ BY ABOVE PROCEDURE
First let’s look at the overall structure of the EMCP 4 response to the query for the first 8 log entries.
Now let’s look at an individual entry. Note from Appendix A, that each entry is 14 registers long; since
each register is 2 bytes long, each entry is 2 x 14 = 28 bytes long. So we can split up the data (let’s
consider only the data portion of the above response message) and deal with each log entry individually.
