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 multiplication is outside the DPT range:
• If the multiplication is greater than the maximum DPT value:
o P = 0
o Ü = 1 (true)
• If the value from the multiplication is less than the minimum DPT value:
o P = 0
o Ü = 1 (true)
• If the value from the multiplication is within the valid range of the DPT:
o P = Product of all linked input values
o Ü = 0 (false)
Other
Inputs not connected are treated as if they did not exist.
