Idle Time 1 (Tid1): IEC 61158-4: This time defines the delay the sender of a telegram, after having received a response (or a token), shall wait until it may send another telegram.
Synchronization Time (Tsyn): (1) Asynchronous transmission Tsyn is the minimum time interval during which each station shall receive idle state (idle = binary "1") from the transmission medium before it may accept the beginning of a send/request or token telegram. 33 bit.(2) Synchronous transmission post transmission gap time (Tptg). at least 4 ~ 32 bit(by user).
Tsyn = Tptg = Tqui = 4 to 32 bit.
