Error message
Cause(s)
Solution
M11
Slave data invalid
This error message has a multiple
meaning and thus depends on the re-
quested command:
1. Readdressing of the slave
Address 32 = 0B was indicated as tar-
get address.
2. Write
parameters
The attempt has been made to write a
value greater than 0x7 to an A/B slave,
ID=0xA.
On 1:
►
Address 0B is not permitted
►
Write valid address
On 2:
►
Write valid value
M12
7.4 Sequence error
During the transfer according to the "7.4
slave protocol" the master detected an
error in the triple sequence of the slave.
Possible causes:
1. Interference on the bus
2. Software error in the AS-i slave
On 1:
►
Remove the cause of the error
On 2:
►
Contact AS-i specialist or manufac-
turer
M13
Timeout in 7.4 transfer
During the transfer to the "7.4 slave
protocol" the master detected a timeout
in the communication with the operating
system.
Possible cause:
Long PLC cycle which slows down the
transfer of the individual 7.4 segments
of the operating system or PLC to the
master to an unacceptable degree:
t > 1 sec.
In this case, the master will end the
most recent 7.4 transfer and will again
enter into normal data exchange with
the respective slave.
►
Shorten the PLC cycle by optimising
the program, avoid program loops
and complex arithmetic operations
M14 Invalid
slave
address
This error message has a multiple
meaning and thus depends on the re-
quested command:
1. The attempt was made to write a
parameter to slave 0.
2. For
readdressing, the address 0 or
0B was indicated as start and target
address.
3. During the attempt to write the ex-
tended ID code 1 the address 0 was
used.
On 1:
►
Correct the slave address
On 2:
►
Indicate a valid address
On 3:
►
Indicate a valid address
