Note: Modbus addresses in the 4xxxx format follow the Modicon protocol specification for point addressing. The actual address sent is the value shown, minus 40001.
In other words, the leading “4” is omitted, and the remaining 4-digit number is decremented so that point 40001 is requested with a value of zero in the actual Modbus
communication. Some Modbus implementations require point addresses to be specified beginning at zero or 40000, instead of 40001. Programing code may also require
addresses which correspond to actual values transmitted, so a value of zero is used to request data beginning at Modbus address 40001.
In many applications, a single Modbus command is used to read all of the data available from the Enercept. For integers, the beginning address is 40001 (or zero in the actual
Modbus command), and for floats the first address used would typically be 40259 (or 258 in the actual Modbus command). Although the first float appears at address 40257,
it is not necessary to read this value because it is a duplicate copy of the kWh value (required by the product firmware). When a block of data is read, the “typical offset” values
index to the data within the block.
"Multiplier required" indicates that a multiplication is required to properly scale the integer value. See Using Integer Data Types section.
