For instance: event logging records when phase A current under critical value, record
includes: phase, event (power on or off), occurrence time, last event duration.
Meanwhile, PMAC201HW supports power ON/OFF event records clearing.
6.2 Parameter Revising Event
PMAC201HW records parameter revising event, depth: 10 records, in chronological
sequence, record content includes: phase, parameter, revising time, occurrence time,
primary value and revised value. Revising without any parameter modified won’t be
recorded.
For intense: Change PT ratio from 100 to 200, the PT ration value (revised item),
revised time, primary value100, revised value 200 all will be recorded.
Meanwhile, PMAC201HW supports resetting function for parameter revising event.
6.3 Data Freezing/ Load Record
PMAC201HW offers a 64M bits - bulk memory to enlarge storage space.
Notice:(1) Sudden power fail will cause at most 1 hour data losing.
(2) Data will be saved normally after electrified 1 hour continuously.
For instance: To check the 2nd record on 2012-03-28, write 0, 12, 3, 28, 2, 1 one by one
to 47001-47006 registers, then read this record from 47007 – 47052 registers.

Setting
Press key to set communicationaddress or baudrate.
Address setting
Step 1. Press key, when“1.xxx” displays on LED, if
the last figure is flashing, the
address can be revised:
Step 2. Press key to change
current address, use key to
move to left, and press keyto confirm and save (The
address range 1 to 247).
Followed picture illustrates
change address into “15”:
“2.xxx” displays on LED, if the
last 3 figures are flashing, the
