Function
Whenever a telegram is received the output starts a recalculation independently if the value has changed.
An overflow will occur if the value from the division is outside the DPT range:
• If the value from the division is greater than the maximum DPT value:
o Q = 0
o Ü = 1 (true)
o F = 0 (false)
• If the value from the division is less than the minimum DPT value:
o Q = 0
o Ü = 1 (true)
o F = 0 (false)
• If the value from the division is within the valid range of the DPT:
o Q = Quotient of the two input values (dividend: divisor)
o Ü = 0 (false)
o F = 0 (false)
• Value of the divisor = 0:
o Q = 0
o Ü = 0 (false)
o F = 1 (true)
Other
Inputs not connected are treated as if they did not exist.
