Table 5-27 Data Recorder Setup
Notes:
1. Changing any of these Data Recorder setup registers will reset the Data Recorder.
2. Recording Offset can be used to delay the recording by a fixed amount of time from the Recording Interval . For example, if the
Recording Interval is set to 3600 (hourly) and the Recording Offset is set to 300 (5 minutes), the recording will take place at 5 minutes
after the hour every hour, i.e. 00:05, 01:05, 02:05…etc. The value of the Recording Offset parameter should be less than the
Recording Interval parameter.
3. Please refer to Section 4.3.3 to configure the Recording Depth and Number of Parameters .

Table 5-28 Data Recorder Parameters
5.10 Time
There are two sets of Time registers supported by the PMC-230 – Year / Month / Day / Hour / Minute / Second
(Registers # 60000 to 60002) and UNIX Time (Register # 60004). When sending time to the PMC-230 over Modbus
communications, care should be taken to only write one of the two Time register sets. All registers within a Time
register set must be written in a single transaction. If registers 60000 to 60004 are being written to at the same
time, both Time register sets will be updated to reflect the new time specified in the UNIX Time register set
(60004) and the time specified in registers 60000-60002 will be ignored. Writing to the Millisecond register
(60003) is optional during a Time Set operation. When broadcasting time, the function code must be set to 0x10
(Pre-set Multiple Registers). Incorrect date or time values will be rejected by the meter. In addition, attempting
to write a Time value less than Jan 1, 2000, 00:00:00 will be rejected.
