冗余从属设备可以使用它检查备份从属设备。请勿将其设置为低于最高使用（冗余）从属地址。光链路模块使用此参数来管理冗余功能。HSA必须至少比总线上存在的主设备和从设备的最高节点地址数大一个。强烈建议不要更改默认值126。最大重试限制此参数表示当在时隙时间内没有从从站接收到响应或确认帧时，FDL（现场总线数据链路层）必须重复请求帧的频率。PROFIBUS PA应用程序可能需要将最大重试限制设置为3-7*Min slave interval此参数指定两个轮询周期之间的最短时间，以使从设备过期。该设置必须大于所有连接从属设备的最大值，否则将生成编译警告并更正该值。
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.
