0x80 End of Interval (EOI) Pulse*

* Setting the interval to EOI causes a record to be logged whenever an EOI pulse

event is generated. This is most commonly used in conjunction with the Digital

I/O Option Cards.

NOTE: The interval between records will not be even (fixed), and thus should not

be used with programs that expect a fixed interval.

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

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)

While the Register List describes what to log, the Item Descriptor List describes how

to interpret that information. Each descriptor describes a group of register items, and

what they mean.
