自动计算确保TQUI小于MinTsdr,否则将生成编译警告,并将该值设置为允许的最高值*设置时间发生中断请求(例如,SYN计时器过期)和必要反应(例如,启用接收器)之间的时间。该值取决于波特率。PROFIBUS PA应用程序在不同波特率下可能需要比默认值更长的时间。目标旋转时间(TTR)目标旋转时间是PROFIBUS网络上一次令牌旋转的预期时间,包括高优先级和低优先级事务以及GAP维护的容差。对于具有一个主机的网络,它必须大于系统反应时间。CI854/CI854A的自动计算确保TTR对于单个CI854/CIL854A或冗余CI854A PROFIBUS主设备及其所有从设备以及用于刀具路由的两个非循环通信以及根据定义的最大重试限制的安全余量足够高
The automatic
calculation ensures that TQUI is less than MinTsdr or a
compilation warning will be generated and the value will be set to
the highest allowed value.
*Setup time The time between the occurrence of an interrupt request (for
example, SYN timer expired) and the necessary reaction (for
example, enabling the receiver). The value depends on the baud
rate.
PROFIBUS PA applications may require longer times than
the default values at the different baud rates.Target
rotation time
(TTR)
The target rotation time is the anticipated time for one token
rotation on the PROFIBUS network, including allowances for highand low-priority transactions and GAP maintenance. For networks
with one master it must be greater than the system reaction time.
The automatic calculation for the CI854/CI854A ensures, that TTR
is high enough for a single CI854/CI854A or a redundant CI854A
PROFIBUS master and all its slaves plus two acyclic
communications used for toolrouting plus a safety margin
