3.1.8. REG Command

The REG command allows to read the Status Register and the Fault Register, and to reset the Fault Register.

The Status Register is a 32-bit register that contains the general information to the status of the unit such as on/off status, update mode etc. See the Status Register section for a detailed description of the register bits.

The Fault Register is a 32-bit register that contains the fault information of the unit such (if any). See the Fault Register section for a detailed description of the register bits.

Command Format:

R/W	Command	Response	Description
R	REG:STATUS:?	#REG:STATUS:<hex_value>	Return the Status Register in hexadecimal representation
R	REG:FAULT:?	#REG:FAULT:<hex_value>	Return the Fault Register in hexadecimal representation [1]
R	REG:FAULT:FIRST:?	#REG:FAULT:FIRST:<hex_value>	Return the first fault that occurred (useful in case of multiple faults) [1]
W	REG:RESET	#AK / #NAK	Resets the Fault Register [2] and the relative Fault bit in the status register

[1] (1,2)

The Fault Register is latching, so if a fault condition occurs, its information is stored in the Fault Register until the reset of the status register (so if, for example, a fault condition occurs and is later solved, the relative bit in the fault register remains valid, until the reset command).

[2]

In order to put the module in ON (see OUT Command), it is necessary to solve all the fault conditions and reset the Fault Register before powering ON the module.
