Whenever a telegram is received the output starts a recalculation independently if the value has changed.
An overflow will occur if the Division value is outside the DPT range:
• If the Division value is greater than the maximum DPT value:
o Q = 0
o Ov = 1 (true)
o E = 0 (false)
• If the Division value is less than the minimum DPT value:
o Q = 0
o Ov = 1 (true)
o E = 0 (false)
• If the Division value is within the valid range of the DPT:
o Q = Quotient of the two input values (Dividend : Divisor)
o Ov = 0 (false)
o E = 0 (false)
• Value of Divisor = 0:

o Ov = 0 (false)
o E = 1 (true)
