and the calculation of additional code of the received number. At the receiver, the LRC is calculated again and
compared with the received LRC. In the calculation of LRC the colon, CR and LF are discarded.
An example of the LRC calculation for the command for reading of continuous 2 words from starting address
2102H in UBZ with communication address 01H is shown in Table 5.6.
5.4.6 Register addresses
The register addresses of measured and calculated parameters of UBZ are given in Table 3.5
The register addresses of programmable parameters are given in Table 3.6.
The register addresses of special and service parameters and their purpose are given in Table 3.4.
The register address of the status and purpose bit data in Table 5.9.
The register addresses of the alarm log are given in Table 5.9.
The register addresses of time settings are given in Table 5.10.
The register address of commands is 903 (Table 5.12).

At the time of UBZ delivery or after the setting of factory parameters (it.5.2.7) there is a record in the
fault logbook about error code 40 and parameter value 10000.
5.4.7 Time parameter registers
The parameters are transmitted in binary decimal code. For example, the code 0x14 in the register of minutes
means 14 minutes.
Registers of time settings allow reading and recording of data.
Register addresses for time settings are shown in Table 5.10.
