自動計算確保TQUI小于MinTsdr，否則將生成編譯警告，并將該值設(shè)置為允許的最高值*設(shè)置時間發(fā)生中斷請求（例如，SYN計時器過期）和必要反應(yīng)（例如，啟用接收器）之間的時間。該值取決于波特率。PROFIBUS PA應(yīng)用程序在不同波特率下可能需要比默認值更長的時間。目標(biāo)旋轉(zhuǎn)時間（TTR）目標(biāo)旋轉(zhuǎn)時間是PROFIBUS網(wǎng)絡(luò)上一次令牌旋轉(zhuǎn)的預(yù)期時間，包括高優(yōu)先級和低優(yōu)先級事務(wù)以及GAP維護的容差。對于具有一個主機的網(wǎng)絡(luò)，它必須大于系統(tǒng)反應(yīng)時間。CI854/CI854A的自動計算確保TTR對于單個CI854/CIL854A或冗余CI854A PROFIBUS主設(shè)備及其所有從設(shè)備以及用于刀具路由的兩個非循環(huán)通信以及根據(jù)定義的最大重試限制的安全余量足夠高
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
according to the defined max retry limit
