例如，如果TTR=20000 tbit，波特率=9.6 kbit/s，看門狗參數(shù)應大于：20000*（1/9.6）*10=2084 ms。例如，開關TTR=20000tbit，波特率=1.5 Mbit/s，則看門狗參數(shù)應該大于：20000*（1/1500）*10=133 ms。下載期間的自動計算禁止看門狗時間太短，并發(fā)出適當?shù)木婊蝈e誤消息*時隙時間時隙時間是主機必須等待事務響應的最長時間。它必須始終大于（>）MaxTsdr+TQUI+11+2+SafetyMargin（請參閱下面的MaxTsdr和TQUI），否則將生成編譯警告，并將該值設置為允許的最小值。設置過高可能會降低性能。PROFIBUS PA可能需要較長的時隙時間設置。
For example, with
TTR = 20000 tbit and baud rate = 9.6 kbit/s, the watchdog
parameter should be greater than: 20000 * (1/9.6) * 10 = 2084 ms.
For example, witch TTR = 20000 tbit and baud rate = 1.5 Mbit/s,
the watchdog parameter should be greater than: 20000 * (1/1500)
* 10 = 133 ms. The automatic calculation during the download
prohibits a too short watchdog time and issues an appropriate
warning or error message.
*Slot time The slot time is the maximum time a master must wait for a
transaction response. It must always be greater than (>)MaxTsdr +
TQUI + 11 + 2 + SafetyMargin (see below for MaxTsdr and TQUI)
or a compilation warning will be generated and the value will be set
to the smallest one allowed. Setting it too high may slow down the
performance.
PROFIBUS PA may require long settings for the slot time.
