例如，如果TTR=20000 tbit，波特率=9.6 kbit/s，看门狗参数应大于：20000*（1/9.6）*10=2084 ms。例如，开关TTR=20000tbit，波特率=1.5 Mbit/s，则看门狗参数应该大于：20000*（1/1500）*10=133 ms。下载期间的自动计算禁止看门狗时间太短，并发出适当的警告或错误消息*时隙时间时隙时间是主机必须等待事务响应的最长时间。它必须始终大于（>）MaxTsdr+TQUI+11+2+SafetyMargin（请参阅下面的MaxTsdr和TQUI），否则将生成编译警告，并将该值设置为允许的最小值。设置过高可能会降低性能。PROFIBUS PA可能需要较长的时隙时间设置。
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.
