OVMS: Renault Twizy User Guide
Low level commands
These commands provide direct access to the SEVCON configuration objects (SDO = service data
object, see CANopen standard).
Reminder: you need to enable CAN write access (feature #15) first, and you may need to clear bit
2 (value=4) in the car bits (feature #14) if you want to get the CFG results.
Command
CFG PRE
CFG OP
CFG READ index_hex
subindex_hex
CFG READS index_hex

CFG WRITE index_hex
subindex_hex value_dec

Function
Enter pre-operational state (needed for some config objects).
Twizy will beep and STOP lamp will be on if successful.
Enter operational state.
Read CANopen SDO object.
index_hex: SDO address (hexadecimal)
subindex_hex: SDO field (hexadecimal)
Read CANopen SDO object string contents.
(Used for fetching fault code descriptions)
index_hex: SDO address (hexadecimal)
subindex_hex: SDO field (hexadecimal)
Write CANopen SDO object.
index_hex: SDO address (hexadecimal)
subindex_hex: SDO field (hexadecimal)
value_dec: new value (decimal)
The command will first read and output the old value before
trying to write the new value.
ATT: the OVMS cannot store any backup values! Save/copy
the old value to be able to restore it later on!
Write-only CANopen SDO object (i.e. no READ before write).
index_hex: SDO address (hexadecimal)
subindex_hex: SDO field (hexadecimal)
value_dec: new value (decimal)
The command will not output the old value. This needs to be used
for write-only SDOs, as the read attempt would result in an error.
ATT: the OVMS cannot store any backup values! Save/copy
the old value to be able to restore it later on!
