KEN-1000x Power Meter communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – 0 ~ 255 station number of KEN-1000x Power Meter.
2) Read command – ALL, STATUS, ANALOG. ( refer <Table 1> ~ <Table 1> )
ALL - read of status and analog data,
STATUS – read of diagnosis and event status,
ANALOG – read of analog data and counter.
3) Read start address – Don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Fixed to 1. ( ALL – 16, STATUS – 2, ANALOG – 14 )
Read schedule example)
READ, 1, ALL, 0, 0, 16,
<Table 1>, <Table 2> are data saving address and contents of STATUS, ANALOG read command.
| Data saving address | Contents |
Remarks |
| Start addr + 0 | 0 ~ 15 bit : Reserved |
save at WORD memory |
| Start addr + 1 | 7 ~ 15 Bit : Reserved 6 Bit : Metering Fail 5 Bit : Abnormal Reset 4 Bit : setting Fail 3 Bit : EEPROM Fail 2 :Bit : memory Fail 1 Bit : Watch Dog Reset 0 Bit : connectoin error |
