Chapter 6 Communication Object Description
Communication object is the media of devices on the bus communicate with other device, that is, just
communication object can communicate with the BUS. The role of each communication objects as following.
(Take 1fold universal dimmer for example)
6.1. Communication object of “Device General”
There are 2 communication objects in
“
Device General
”
in Fig.6.1 and functions are shown in table 6.1.
Fig. 6.1 Communication object of “Device General”
Note: “C” in “Flag” column in the below table means that the object has a normal link to the bus; “W”
means the object value can be modified via the bus; “R” means the value of the object can be read via the
bus; “T” means that a telegram is transmitted when the object value has been modified; “U” means that
value response telegrams are interpreted as a write command, the value of the object is updated.

This object is used to declare the working condition by sending “1” or “0” to the bus cyclically, which is enabled
when selecting “send value '0' cyclically” or “send value '1' cyclically” in the parameter “Send object 'in operation'“ and
disabled when selecting “no”. It will send “0” with option “send value '0' cyclically” and “1” with “send value '1'
cyclically”.

No DPT
This object is used to report the error status of the system. It will be disabled with “Error report”, and report error
information when the system has the malfunction with the option “Enable”. It will also send an alarm to switch off the
device with over temperature, overload or short circuit.
Assuming an 8-bit command (telegram code) as: 76543210
Universal dimmer
8 bits are 0, that is the telegram
“
0
”
– the system working normally
No. 0 is 1 – Channel 1 short circuit or over load
No. 1 is 1 – Channel 2 short circuit or over load
No. 2 is 1 – Channel 3 short circuit or over load
No. 3 is 1 – Channel 4 short circuit or over load
No. 4 is 1 – the radiator temperature more than 70
℃
No. 5 is 1 – the radiator temperature more than 90
℃
Other are not used
