Comparator
This job compares the value of an input object with the value of another or with the worth of a static value. Result will be evaluated by “true” or “false”. Output can be parameterized independent from input.
Job Name
Required field. Assign a unique name for the job. The name must not contain more than 15 characters.
Gate Group Addresses
By Gate Group Addresses job will be released or blocked. The release object releases or locks the job. It is about an EIS1 object:
Field blank = Job is released.
Field completed, value 1 = Job released.
Field completed, value 0 = job locked.
Field completed, no value = job locked.
As soon as one address is filled in, release will behave respective to the value of the group address. If no value was sent to the address and the address is presently without values, job will be blocked.
Input 1 und 2
Both inputs will be compared with another according to adjusted comparison operations. Depending on result, output will be send either “true” or „false“. Input objects get following parameters:
Group address
The group addresses of the input object.
EIS Format
Here you can choose the EIS type of input object. Following EIS types were supported by comparator:
EIS 1 (switching, 1Bit)
EIS 2 (dimming, 1,4,8 Bit)
EIS 3 (time, 3 Byte)
EIS 4 (date, 3 Byte)
EIS 5 (floating point, 16Bit)
EIS 6 (percent 0-100%, 1 Byte)
EIS 8 (priority, 2 Bit)
EIS 9 (floating point, 32 Bit)
EIS 10 (counter, 16 Bit)
EIS 11 (counter, 32 Bit)
EIS 14 (counter, 8 Bit)
EIS 15 (text, 14 Byte)
Static
If that input is activated instead of the group address value, the value of the bordering entry field will be used for comparison operations.
Factor and offset
You can format the value of group address with help of these both parameters. The value will be multiplied by factor, offset will be added.
Operation
Following comparison operation are available:
“=” similar
“<>” dissimilar
“>” greater than
“<” smaller than
“>=” greater or equal
“<=” smaller than or equal
Every receiving of a telegram to input object causes comparison operation once again.
Output (“FALSE” or “TRUE”)
According to which result of comparison operation, respective output will be send. Output could have following parameters:
Group address
To every output a group address will be dedicated. Both outputs can have the same address.
EIS value
If output is marked as static, following EIS types are available
EIS 1 (switching, 1Bit)
EIS 2 (dimming, 1,4,8 Bit)
EIS 3 (time, 3 Byte)
EIS 4 (date, 3 Byte)
EIS 5 (floating point, 16Bit)
EIS 6 (percent 0-100%, 1 Byte)
EIS 8 (priority, 2 Bit)
EIS 9 (floating point, 32 Bit)
EIS 10 (counter, 16 Bit)
EIS 11 (counter, 32 Bit)
EIS 14 (counter, 8 Bit)
EIS 15 (text, 14 Byte)
Static
For the output value, the value of bordering entry field will be used. Value has to match adjusted EIS typing.
Non-Static output
Output carries no fixed value. For output one of the following values are used:
Activating telegram (Input 1 or 2)
Last telegram from input 1
Last telegram from input 2
In case on input is static, no on input object received telegram could be sent to output.
Volatile
Group address value cannot be overwritten by external telegrams (directly from KNX/EIB).
Changes
Output will be sent to bus, only if the output value changes. In case this entry is not activated, output value will be sent out after every new operation again and again. Changes only refers to the value of the respective output object. If output object remains static, no modifications of output value can happen. This setting is only practical by using a dynamic output.
