7.15.8 Analog Input Interrupt Positive Delta Unsigned (Object 0x6428)
Object 0x6428 defines the negative fluctuation range (delta) relative to the
last transmitted value when counting up and affects the transmission of
object 0x6401 accordingly
The specified fluctuation range refers to the data transmitted in object
0x6401 and accordingly must be specified as an unsigned value with the
same value representation.
Object 0x6401 will be transmitted (CAN transmission) if all of the following
conditions are met:
•
The current value (ENTRY into 0x6401) is greater than the last transmit-
ted value. The difference's magnitude is greater than the fluctuation
range (Positive Value Difference 0x6428).
•
Object 0x6421 is set to enable.
•
The global interrupt in object 0x6423 has been enabled with: TRUE.
If the current value is less than the last transmitted value, object 0x6401 will
be transmitted. If this behavior is not desired, object 0x6421 must be
enabled and disabled accordingly.
