7.3.- MODBUS COMMANDS
Two different memory maps have been implemented for the Measurement, Energy and Voltage
and Current harmonics variables. However, they have the same functions:
Map 1, uses the addresses of the CVM-MINI device, entering the addresses of the new pa-
rameters measured by this new device.
Map 2, uses the addresses of the CVM-C10 device (adding 0x1000 to all addresses).
Except for 3 parameters, the CVM-C10 and the CVM-E3-MINI use the same parameters.
Map 2 should be used if a Modbus map is going to be implemented from scratch. However, if the map
is already being used in another device, use Map 1 for CVM-MINI and Map 2 for CVM-C10.
All the adresses of Modbus memory are in Hexadecimal.
7.3.1. MEASUREMENT VARIABLES
For these variables is implemented the Function 0x03 and 0x04.
