Function
Whenever a telegram is received the output starts a recalculation independently if the value has changed.
An overflow will occur if the calculated value is outside the DPT range:
• If the calculated value is greater than the maximum DPT value:
o S = 0
o Ov = 1 (true)
• If the calculated value is less than the minimum DPT value:
o S = 0
o Ov = 1 (true)
• If the calculated value is within the valid range of the DPT:
o S = Sum of all linked output values
o Ov = 0 (false)
Other
Unlinked inputs are treated as if they did not exist.
