Status object
The following parameter activates an object for the state:
Figure 32: Ventilation control - Status object
The following settings are available:
•
1 Byte Output
•
If the state object is parameterized as 1 Byte, the object sends the current level as value,
e.g. value 1 for level 1, value 2 for level 2…
With the setting “step
-
switch as byte”, the current control value is sent
.
•
1 Bit Ventilation active
In this case, the value 1 is sent when the ventilation is active and the value 0 when the
ventilation is inactive.
4.8.4.2 Step Switch
–
binary coded
The binary-coded step controller is identical in its functionality to the normal step controller as
described in "4.8.4.1 Step switch bit-coded". Only the output level is already binary coded.
Object 177 forms bit 0, object 178 bit 1 and object 179 bit 2.
The following table shows the binary-coded switching of the output level:
normal step-switch
binary value step-switch binary coded
Level 0
000
Objects 177, 178, 179 = 0
Level 1
001
Object 177 = 1, Objects 178 & 179 = 0
Level 2
010
Object 178 = 1, Objects 177 & 179 = 0
Level 3
011
Objects 177 & 178 = 1, Object 179 = 0
Level 4
100
Object 179 = 1, Objects 177 & 178 = 0
Table 68: Settings - : Step-switch binary coded
The following table shows the communication objects for the step switch binary coded:
