This busparameter defines the delay the sender of an unacknowledged telegram shall wait until it may send another telegram. Tid2 is the maximum value of 2 variables: 1) MaxTSDR 2) TQUI + 2*TSET + 2 + TSYN In most cases MaxTSDR has the highest value (Tid2 = MaxTSDR). A typical message that uses Tid2 is the Global Control broadcast with PROFIBUS DP.
