Register number and name tagging for dynamic data
The register numbers shown here are used for data and name tagging required for dynamic data display in your custom web pages.
Modbus registers - use this information if your i.CanDoIt server has Modbus registers as its primary data element.
Integer registers: 1-999
Floating point registers: 1001-1999
Note that floating point values (IEEE-754) in Modbus are represented by two consecutive registers. When reading Modbus via Modbus protocol, you need to read two registers to get the complete value. When referencing registers in HTML, you only need to reference one register, but it must be the first register, and will always be an odd number. Therefore, for example, the first three available floating point values are found at reg1001, reg1003, and reg1005 as would be referenced in User HTML.
BACnet registers - use this information if your i.CanDoIt server has BACnet objects as its primary data element.
BACnet registers are calculated to provide object time and object number encoded into a single number that can be referenced in User HTML as reg1001, etc. The first Analog Input would be reference as reg1, the first Analog Output would be referenced as reg1001, the first Binary Input would be referenced as reg3001, the first Multi-state Value would be referenced as reg19001, etc.
