Subject to modifications.
User interface objects and properties (UIO interface)
The SMI software
Property 80
The property with the ID 80 is only readable and reproduces the mask of
the SMI slaves found in a form that they would also use in group addressing
according to the SMI standard, were all drives referenced together.
Properties 81 to 88
The 8 properties with the IDs 81 to 88 reproduce (only readable externally)
the presence status which is ascertained after initialisation by the actuator
at the SMI bus, in other words the data of the particular slave drive identi-
fied. Here, the end numbers of the property ID (1 … 8, regardless of whether
read hexadecimally or decimally) correspond to the number of the channel
to which the slave has been assigned according to ETS parametrisation.
The following information is coded in the 8 bytes of each of these proper-
ties in sequence:
Accessing properties in the user interface object 50001, with the help of
Device Editor from the ETS3 bundle, is relatively laborious and time-con-
suming, and it requires both a certain degree of practice and a precise
knowledge of the above-described properties and their individual meanings.
In particular, SMI telegrams, which should be transmitted to SMI slaves via
the gateway property 64, must be previously assembled manually and
entered in hexadecimal notation byte-by-byte. Using the Device Editor it is
practically impossible to track closely the development of property values
which are continuously adapted by the actuator to each situation, for
instance the state of movement bytes in property 65. This is because
values can only be read in again with the whole object, each one taking
some time.
In addition, it is the software and not the licensing of the Device Editor that
comes as standard in the accessories bundle of ETS3. If property values
also need to be altered (written into the actuator) using the Device Editor,
an extended licence for ETS3 must be acquired if the manufacturer func-
tions of ETS3 are not already co-licensed.
All these restrictions should be remedied with the SMI software. The SMI
tool is a diagnostic aid with very wide-ranging possibilities. It will make
access to individual actuators and the corresponding properties of the
user interface object 50001 much easier.
Once the list of physical addresses of all the SMI actuators available in the
EIB is imported, an individual actuator and its connected SMI bus can be
easily selected. The list itself can be directly exported from the ETS, or
even edited manually with an ASCII editor.
After an individual SMI actuator has been selected, the read-only values
of properties 65, 80 and 81 to 88 are displayed clearly in tabular form. The
individual values of property 65 are continuously updated and are con-
stantly visualised in a clear assignment to the drive IDs.
Work with the gateway property 64 is then made considerably easier. Any
commands can be entered as hex strings and the processing and respon-
se status is tracked in real time. Simple SMI standard commands can be
transmitted with clear addressing of individual drives by just clicking spe-
cial buttons. For example, the physical identification of individual drives
whose key ID was previously unknown and was only read out with the SMI
tool from the properties 81 to 88 is made far simpler.
Likewise it is also possible to use special buttons to trigger the special re-
initialisation or calibration commands, transmissible via the control byte in
property 64.
Another feature can be added to the SMI tool, if requested by future users:
on an additional tab, a key ID scan on the SMI can be carried out by the
SMI tool via the gateway property 64 in the user interface object 50001.
Here, the SMI tool uses the same addressing algorithm as the SMI drive
8 actuator during automatic addressing. Up to eight of the found slaves are
programmed with the slave addresses 1 to 8, whereby the address 8 is
assigned to the highest found SMI key ID and slave address 1 is assigned to
the lowest. As the actuator itself only functions in this process as a gateway
and is otherwise unoperational, it is recommended to allow a re-initialisa-
tion so that the internal actuator data on the slaves is updated accordingly.
The SMI tool is already available as a beta version and from the end of
March 2008 (in time for the Light + Building 2008 trade fair) will be down-
loadable as a final release from the APT website.
For APT GmbH, the extent to which the SMI tool will be upgraded with
additional features in future is dependent on the further development and
distribution of SMI technology and, finally, customer requirements.
Support, for instance, for the transmission of prepared sequences or of
whole manufacturer-specific parameter sets directly to individual drives
has been contemplated, but has not, for the moment, been implemented.
Byte Index
Meaning
0
Number of the channel to which the drive has been
assigned during initialisation.
1 high-Nibble Drive type ID according to SMI standard
(manufacturer-specific)
1 low-Nibble Manufacturer ID according to SMI standard
2 ... 5
Key ID of the drive according to the SMI standard
(read from left to right, the highest-value byte at the
position with the smallest index / manufacturer-specific)
6 ... 7
Value of the relative SMI position difference which is
determined during calibration. If the channel has not
yet been calibrated, but has been configured as a blind,
FFFFh appears (0000h if configured as a shutter).
