Register List:
Registers:
0x7919 - 0x798D
Size:
1 register per list item, 117 list items
The Register List controls what Modbus Registers are recorded in each record of the Historical
Log. Since many items, such as Voltage, Energy, etc., take up more than 1 register, multiple regis-
ters need to be listed to record those items.
For example: Registers 0x03E7 and 0x03E8 are programmed to be recorded by the historical log.
These registers program the log to record "Primary Readings Volts A-N."
• Each unused register item should be set to 0x0000 or 0xFFFF to indicate that it should be
ignored.
• The actual size of the record, and the number of items in the register list which are used, is
determined by the # registers in the header.
• Each register item is the Modbus Address in the range of 0x0000 to 0xFFFF.
Item Descriptor List:
Registers:
0x798E - 0x79C8
Size:
1 byte per item, 117 bytes (59 registers)
