5.8 Time Registers
There are two sets of Time registers supported by the PMC-PMC-512-D – Year / Month / Day / Hour /
Minute / Second (Registers # 60000 to 60002) and UNIX Time (Register # 60004). When sending time to
the PMC-512-D 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.
