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 )
