Circutor CVM-C10 User Manual

4.10.3.5. Power status.
All the Modbus map addresses are hexadecimal.
The 0x04 function is implemented for this variable.
This variable indicates the quadrant in which the device is operating.

4.10.3.6. The unit’s serial number.
All the Modbus map addresses are hexadecimal.
The 0x04 function is implemented for this variable.
Table 27:Modbus memory map: Serial number.
The unit’s serial number
Variable Address Default value
Serial number 578 - 579 -
4.10.3.7. Device conguration variables.
All the Modbus map addresses are hexadecimal.
The 0x04 and 0x10 functions are implemented for this variable.
The device’s Modbus function does not check whether the variables recorded are within the
correct margins, they are only checked when they are read from the EEPROM. So if any
parameter is recorded with an incorrect value the device will be congured with its default value.
The Modbus conguration will not take effect until the device is reset.
4.10.3.7.1. Transformation ratios.
