The PMC-53A-E has one SOE Log and five DR Logs. Each of these logs has a Log Pointer that indicates its current logging
position. The range of the Log Pointer is between 0 and 0xFFFFFFFF, and it is incremented by one for every new log
generated and will roll over to 0 if its current value is 0xFFFFFFFF. A value of zero indicates that the SOE or DRx does not
contain any Log. If a Clear Log is performed via communications, its Log Pointer will be reset to zero and immediately
incremented by one with a new “Clear SOE via Communications” event. When the number of events is larger than the Log
Depth, only the latest 100 SOE Logs (up to 120000 DR Logs) will be stored on a FIFO basis.
Use the following equation to determine the latest log location:
Latest Log Location = Modulo [Log Pointer/Log Depth]
where Log Pointer may be one of the following:
SOE Log Pointer, DR1 - DR5 Log Pointers
and Log Depth is as follows:
SOE Log Depth = 100 (fixed)
DRx Log Depth = DRx Recording Depth (see Section 5.11.5 Data Recorder Setup)
7)
The Device Operating Time means the accumulated Operating Time whenever any per-phase Current exceeds Current
Threshold of Device Operating Time (Register #6049). The Device Operating Time data is stored in non-volatile memory
and will not suffer any loss in the event of a power failure.
8)
The range of the Log Pointer for Daily Freeze Log and Monthly Freeze Log is between 0 and 0xFFFF.
9)
When the Wiring Mode is 1P2W L-N or 1P2W L-L, the L2 and L3 phase voltages and currents have no meaning, and their
registers are reserved.
10)
When the Wiring Mode is 1P2W L-N, 1P2W L-L or 1P3W, the Sequence Components U1/I1, U2/I2 and U0/I0 have no
meaning and their registers are reserved.
5.2 Energy Measurements
The Energy registers have a maximum value of 999,999,999 and will roll over to zero automatically
when it is reached. The actual energy value is 0.1 times of the register value.
