Functional commands description
10.3.1
Reset
The
‘reset’
functional command execution is similar to the device power-up. This reboot phase is necessary if the
address or/and the baud rate are modified and some settings changes are only taken into account after an EEPROM
storage followed by a reset.
10.3.2
EEPROM storage
eNod4
configuration and calibration are stored in a non-volatile memory (EEPROM). If changes are made in the device
configuration, sending to
eNod4
the
‘EEPROM storage’
functional command will allow
eNod4
to keep these
modifications after a power shutdown or the reception a
‘reset’
functional command.
Moreover the settings listed below need to be stored and will only be taken into account at the next device reboot:
•
span adjusting coefficient
•
calibration place
g
value
•
place of use
g
value
•
stability criterion
•
legal for trade activation switch
•
power-up zero
•
A/D conversion rate
•
Functioning mode and communication protocol
•
Analog output voltage and current
10.3.3
Restore default settings
The
‘restore default settings’
command causes
eNod4
to be set back to its default configuration. The default
configuration corresponds to the one on delivery that means with factory settings. Be careful when using this
command, all the default settings are recovered including the stored calibration and the legal for trade indicators.
Note:
this functional command is not available in CANopen® communication protocol.
10.3.4
Zero
When receiving a
‘zero’
functional command
, eNod4
acquires a volatile zero (gross measurement is set to 0) value if
the following conditions are respected:
•
measurement is stable
•
Current gross measurement is within a ±10% (±2% if the legal for trade option is enabled) range of the
‘maximum capacity’
.
Otherwise, after five seconds the command is cancelled and an execution error is reported. This value is not stored in
EEPROM.
