A.3.6 Command Encoding
OK
Bit 7 Bit 0
Standard message used to confirm that an action was performed
correctly by the TCM.
In case of full duplex communication it may happen that serial
telegrams get corrupted and lost. Therefore it is recommended to
check for “OK” where applicable.
ERR
Bit 7 Bit 0
Standard error message response if after a TCT command the
operation could not be carried out successfully by the TCM.
SET_BASEID
Bit 7 Bit 0
With this command the user can rewrite its ID range base num-
ber. The most significant ID byte is BaseIDByte3. The informa-
tion of the 25 most significant bits is stored in FLASH.
The allowed ID range is from 0xFF80_0000 to 0xFFFF_FFFE.
32 0
BaseID
This command can only be used a maximum number of 10 times.
After successfully ID range reprogramming, the TCM answers
with an OK telegram. If reprogramming was not successful, the
TCM answers sending an ERR telegram if the maximum number
of 10 times is exceeded or an ERR_IDRANGE telegram if the
BaseID is not within the allowed range.
