Data addresses and encodingPresentationData which are similar from the application viewpointare grouped together in adjacent address zones:c the synchronization zone is a table which containsthe absolute date and time for time tagging of events,c the identification zone contains system typeinformation pertaining to the identificationof the Sepam 2000 equipment,c the events zone is a table which containsa maximum of 4 time tagged events available via Jbuscommunication,c the automation zone contains the Sepam 2000logical data and PLC event counters,c the test zone is a 16-word zone that is accessiblevia communication by all the Jbus functions, in bothreading and writing modes, to facilitate communicationtesting at the time of commissioning. The Jbus mastercan write or read any value without disturbing Sepam2000 operation,c the measurements x 1 zone contains the analog measurements,c the measurements x 10 zone contains the same analog dataas the measurements x 1 zone, but in a different format: the unit order is multipliedby 10. This zone is used for applications in which the data in the measurements x 1zone are liable to exceed the maximum value possible,c the measurement (32 bits) zone contains certain measurements of themeasurements x 1 zone expressed in 32 bits,c the Sepam 2000 S46 measurement zone contains the measurements whichare specific to this type of Sepam 2000.These 4 analog measurement zones are refreshed simultaneously.c The compact zone contains the characteristic data most often used in the mimicdiagrams. They are grouped together to provide quick access via Jbuscommunication.c The configuration zone contains information pertaining to the hardware andsoftware configurations; it allows precise identification of the Sepam 2000 model.The data addresses are independent of the Sepam 2000 model.Sepam 2000 sets data to 0 for the functions which are not available.In the tables blow:The first column gives the name of the Sepam 2000 information; the word addressand bit address columns indicate the Jbus address of the information.The access column indicates read or write mode access to read or write data.The “format” and “unit” columns indicate the data encoding. The reader should referto the section entitled “Jbus data encoding” in the appendix which describesJbus protocol for a more detailed explanation of the meaning of each of the columnsin the table.Synchronization zoneThe synchronization zone is a table which contains the absolute date and timefor the time tagging function. Time messages should be written in a single blockcontaining 4 words, using the Jbus n° 16 function “word writing”.Messages can be read word by word or by groups of words using function n° 3.synchronization zone word address access Jbus functionenabledbinary time (year) 0002 read/write 3,16binary time (month+year) 0003 read 3binary time (hours+minutes) 0004 read 3binary time (milliseconds) 0005 read 3See “time tagging of events” chapter for data format.Identification zoneThe identification zone contains system type information pertainingto the identification of the Sepam 2000 equipment.Some of the information in the identification zone is also found in the configurationzone at the Jbus address FC00h.identification zone word address access Jbus function format valueenabledmanufacturer 0006 read 3 none 0100equipment 0007 read 3 none 0000customer + Sepam 2000 type 0008 read 3 none Jbus slaveidentificationn° + 0y(see FC01)communication version 0009 read 3 none equal to wordFC02reserved 000A - 000B read 3 none 0000equipment status 000C read 3 X equal to word0C8Freserved 000D read 3 none 0000reserved 000E read 3 none 0000address to another zone 000F read 3 none FC006 Jbus/Modbus communication
