冗余從屬設備可以使用它檢查備份從屬設備。請勿將其設置為低于最高使用（冗余）從屬地址。光鏈路模塊使用此參數(shù)來管理冗余功能。HSA必須至少比總線上存在的主設備和從設備的最高節(jié)點地址數(shù)大一個。強烈建議不要更改默認值126。最大重試限制此參數(shù)表示當在時隙時間內(nèi)沒有從從站接收到響應或確認幀時，F(xiàn)DL（現(xiàn)場總線數(shù)據(jù)鏈路層）必須重復請求幀的頻率。PROFIBUS PA應用程序可能需要將最大重試限制設置為3-7*Min slave interval此參數(shù)指定兩個輪詢周期之間的最短時間，以使從設備過期。該設置必須大于所有連接從屬設備的最大值，否則將生成編譯警告并更正該值。
Redundant slaves may use it for checks of the backup slave. Do
not set it below the highest used (redundant) slave address.
Optical link modules uses this parameter to manage the
redundancy functionality. The HSA has to be at least one greater
than the highest number of node addresses for masters and slaves
present on the bus.
It is highly recommended not to change the default of 126.
Max retry limit This parameter indicates how often the FDL (Fieldbus Data Link
Layer) must repeat the request frame when no response or
acknowledge frame is received from the slave station within the
slot time.
PROFIBUS PA applications may require that you set the
max retry limit to 3-7.
*Min slave
interval
This parameter specifies the minimum time between two polling
cycles for a slave to expire. The setting must be greater than the
maximum value for all connected slaves, or a compilation warning
will be generated and the value corrected.
