SECTION 4 MODBUS PROTOCOL
If there is no enough memory for one more hourly data, the oldest record is deleted and the
latest record is saved to first file memory. In this case, the last saved file number will be“1”.
User can access this number with querying 1360th modbus address (refer to
Example for upper case;
1st file memory=> Hourly Data Record-1921
2nd file memory=> Hourly Data Record-1920
3rd file memory=> Hourly Data Record-3
.
.
.
19th file memory=> Hourly Data Record-1919
20th file memory=> Hourly Data Record-1920
When one more houlrly record is come, the last saved file number will be “2”.
Example of upper case;
1st file memory=> Hourly Data Record-1921
2nd file memory=> Hourly Data Record-1922
3rd file memory=> Hourly Data Record-3
.
.
.
19th file memory=> Hourly Data Record-1919
20th file memory=> Hourly Data Record-1920
Briefl , when Klea’s hourly memory is filled completely, oldest record is deleted and new
record is saved in the deleted record’s memory.
The ‘last saved file number’ inside the hourly memory can be accessed from the 32-bit
parameter starting from Modbus address 1360
.
E.g.:
Assume that a programmer will try to access a Klea with a slave ID number 1. Assume also
that the last saved hourly file number of this device is 17. In this case, data request and
Klea response will be as follows:
