ABB i-bus KNX
Parameters
Description of parameters
Change in %:
The value change is defined as follows:
(NEW_VALUE – LAST_SENT_VALUE) / LAST_SENT_VALUE
If NEW_VALUE = LAST_SENT_VALUE = 0, result is 0%
If NEW_VALUE <> 0 and LAST_SENT_VALUE = 0, result is 100%
Function
Whenever a telegram is received the output starts a recalculation independently if the value has changed.
Bus voltage failure, download and restart
The output values are not saved. Cyclic sending starts once the output receives a valid value.
Output values that cannot be sent on the bus (e.g. due to bus load or bus voltage failure) are overwritten
by newer values.
