IQ 150S/250S B: Modbus Map
The limit # byte is broken into a type and an ID.
3.
Historical Log 1 (2)
: The Historical Log records the values of its assigned registers at the pro-
grammed interval.
NOTE:
See Section B.5.3, Number 1, for details on programming and interpreting the log.
4.
Historical Log 2 (3)
: Same as Historical Log 1.
5.
Historical Log 3 (4)
: Same as Historical Log 1.
B.5.3: Block Definitions
This section describes the Modbus Registers involved in retrieving and interpreting an IQ 250S
meter’s Log. Other sections refer to certain 'values' contained in this section. See the correspond-
ing value in this section for details.
NOTES:
• “Register” is the Modbus Register Address in 0-based Hexadecimal notation. To convert it to 1-
based decimal notation, convert from hex16 to decimal10 and add 1. For example: 0x03E7 =
1000.
• “Size” is the number of Modbus Registers (2 byte) in a block of data.
Historical Log Programmable Settings:
The Historical Logs are programmed using a list of Modbus Registers that will be copied into the
Historical Log record. In other words, Historical Log uses a direct copy of the Modbus Registers to
control what is recorded at the time of record capture.
To supplement this, the programmable settings for the Historical Logs contain a list of descriptors,
which group registers into items. Each item descriptor lists the data type of the item, and the num-
Bit 0 1 2 3 4 5 6 7
