*All above data can not be monitored without VT unit.
*The active and reactive energy are stored in the EEPROM of Extension module (EX1) when the power supply form Power supply
module (P1-P5) is cut off.
*1 Addresses 0518h-0520h can be accessed only from the even number address.
If the byte count of start address 0518h and 051Ah etc. is 2, 3, 5, or 6-byte, the error code (illegal data address code :02h) is
returned.
＜Example＞ In case of monitoring active energy （0518H）.
