TSPP telegram The first 3 bytes of the message contain the letters “T”, “S”, “P” The 4th byte contain the number of words of the data part of one time-stamped data The 5th and 6th bytes (integer format) contain the size in words of all the time-stamped dataEach time-stamped data is composed of • A particular header containing the time stamp in STEP 7

DATE_AND_TIME format • The origin of the data: DB number and start address inside

the DB • Data which size is defined in the 4th byte of the global

header
