Command object

Index 2000 ASI Command

You can send commands to AS-i slaves with index 2000. This is possible both during the offline phase (no other commands on the AS-i bus) and during the management phase. In the management phase, however, you can address only AS-i slaves that are not activated.

Index (hex)	Name	Meaning	Data type	Flags	Default
2000:0	ASI Command	Max. subindex	UINT8	RO	0x03 (3_dec)
2000:01	Request	Slave address (see table below)	OCTET-STRING[4]	RW	{0}

Bit	Value	Description
0 - 4	0 - 255	Command sequence number (should be incremented so that the command is sent)
8 - 15	1	reserved
	2	reserved
	3	reserved
	4	AS-i command write parameter
	5	reserved
	6	reserved
	7	AS-i command addressing call If an address unequal 0 is specified in bits 16 to 23, the AS-i command "Delete operating address" is called first, since the address can only be set if it was previously set to 0.
	8	reserved
	12	AS-i command change extended ID code (slave must have address 0)
16 - 23	0 - 63	Address of the AS-i slave to which the command is to be sent (32 is not permitted)
24 - 31	0 - 31	AS-i command data: • for AS-i command Write parameter: Parameter data • for AS-i command Addressing call: new address • new ID code with AS-i command change extended ID code

Response

(see following table)
For acknowledgement of AS-i command (AS-i command value bit 4 set): write parameter
Bits 31 to 24 return the data handed over in the call of the AS-i command (bits 31 to 24 of the AS-i command).

For acknowledgement of AS-i command (AS-i command value bit 7 set): addressing call
If the error bit (bit 15) is not set, bits 31 to 24 contain the value 00_hex.
If the error bit (bit 15) is set, bits 31 to 24 contain an error code. (see following table)

OCTET-STRING[4]

{0}

Bit	Description
0 - 7	Command sequence number from the request
8 - 14	Corresponding to bits 8 to 15 of the command call.
15	Error bit: If bit 15 is set, this means that an error occurred during the execution of the command and an error code is output in bits 31 to 24!
16 - 23	Address of the AS-i slave to which the command was sent.

Bit	Value	Description
24 - 31	0x00	Address modification was successful.
	0x11	No slave exists with an address that was specified as the old address.
	0x22	Address 0 is currently assigned to another slave. In order to change the address of an AS-i slave, the EL6201 must first assign the address 0 to the slave in order to address it again afterwards from there.
	0x36	A slave with the address that was specified as the new address already exists.
	0x47	After deleting the old address, no slave with address 0 exists.
	0x58	After deleting the old address, an error is generated during reading of the extended ID code 1 of slave 0. Address changes for A/B slaves also require the extended ID code 1.
	0x69	After writing of extended ID code 1, no slave with address 0 exists.
	0x6B	After writing of the new address, the slave with the new address is not available during reading of the ID code.
	0x6C	After writing of the new address, the slave with the new address is not available during reading of the status.
	0x7D	The address could not be saved permanently (non-volatile).
	0x7E	The extended ID code of an A/B slave could not be saved permanently (non-volatile).
	0x7F	ID code 1 is invalid for A/B slaves
	0x83	The new address is a B address. If slaves are to be operated on two parallel addresses in address areas A and B, e.g. 10A (10) and 10B (42), both slaves have to support B addressing. In this case, the parallel A address contains a slave that does not support B addressing!
	0x84	The new address is a B address. The slave selected with the old address is, however, not an A/B-slave, i.e. it does not support the B-addresses (1B to 31B).
	0x85	The new address is an A address. Slave is not an A/B slave: the associated B slave for the new address exists.

Index 2010 AS-i string command

Object 0x2010 can be used to send string commands to the AS-i slaves (analog slaves with profile 7.4 and CTT2 slaves with M4 profile). This is only possible if the AS-i master is already in the data exchange phase and the "Data Exchange Active" bit in AS-i control is set.
