SECTION 4 MODBUS PROTOCOL
4.5.2 KLEA Setting Parameters
Operator/programmer should use‘10H - Write Multiple Registers and‘06H - Write Single
Register’ to change settings parameters.
Operator/programmer should use ‘0x3H - Read Holding Registers’ function to read setting
parameters.
1 register -> comprises of 2 bytes.
After Klea setting parameters have been changed, in order for the new values to be
saved in non-volatile memory;
0x0000 should be written to register 1998, and
0x0001 should be written in register 1999, within 60 seconds following the last setting change.
Only after that, changes will be stored in the permanent memory.
NOTE1:
3 parameters given with“RO (Read Only)” in Table 4-5 are read-only data. They cannot be
changed by the user. This data is as given below:
• Serial Number
• Firmware Version
• Compiler Version
NOTE2:
1998 addressed variable at the end of Table 4-5 is a “W (only writable)” variable.
