    CET Electric Technology a particular DO operation. The DO will be “Disarmed” automatically if an “Execute” command is not received within 15 seconds after it has been “Armed”. If an “Execute” command is received without first having received an “Arm” command, the meter ignores the “Execute” command and returns the 0x04 exception code.

    CET Electric Technology 5.10 Time There are two sets of Time registers supported by the PMC-660 – Year / Month / Day / Hour / Minute / Second (Registers # 60000 to 60002) and UNIX Time (Register # 60004). When sending time to the PMC- 660 over Modbus communications, care should be taken to only write one of the two Time register sets.
