|
|
* Generic Modbus energy meter
|
|
*
|
|
* - Supports single three phase device or three single phase devices of same model on bus.
|
|
* - For easy configuration of modbus energy monitor device(s) use:
|
|
* - a rule file called modbus
|
|
* - a script using >y
|
|
* - a filesystem file called modbus.json
|
|
*
|
|
* See files configurations.md and value_pair_description.md in folder energy_modbus_configs
|
|
*
|
|
* Restrictions:
|
|
* - Supports Modbus single and double integer registers in addition to floating point registers
|
|
* - Max number of user defined registers is defined by one rule buffer (511 characters uncompressed, around 800 characters compressed)
|
|
*
|
|
* To do:
|
|
* - Support all three rule slots
|
|
* - Support other modbus register like integers
|
|
*
|
|
* Test set:
