HIMA X-SB01 985210207模拟量模块
热交换CI854A支持热交换。它可以在线更换,不会对连接到CEX总线的其他单元造成任何干扰。在热移除和随后的插入之后,该单元将自动配置。在冗余配置中,可以在不干扰主单元的情况下更换备用单元。这包括如果设备出现故障,可以在线更换。为了支持热交换,不需要配置。运行中的热配置(HCIR)在运行中进行热配置时,可以在线配置从属设备,而无需初始化PROFIBUS通信。当循环通信保持活动时,新的或更改的配置被下载到从设备。如果从属设备支持HCIR,则可以在线添加或删除I/O单元。在重新配置期间,CI854/CI854A和从机之间的循环数据传输停止。CI854/CI854A保持输入值,从机保持输出值。在完成重新配置之后,循环数据传输将基于新的配置数据进行。
Hot Swap
The CI854A supports hot swap. It can be replaced online, without any disturbance
to other units connected to the CEX-Bus. After hot removal and the subsequently
insertion the unit gets configured automatically.
In a redundant configuration, the backup unit can be replaced without any
disturbances to the primary unit. This includes that the unit can be replaced online if
it becomes faulty.
For support of hot swap no configuration is necessary.
Hot Configuration in Run (HCIR)
With hot configuration in run a slave can be configured online without initialization
the PROFIBUS communication. The new or changed configuration is downloaded
to the slave while the cyclic communication keeps active.
If a slave supports HCIR I/O-units can be added or deleted online. During
reconfiguration the cyclic data transmission between CI854/CI854A and the slave is
stopped. The CI854/CI854A keeps the input values and the slave the output values.
After finishing the reconfiguration the cyclic data transmission will proceed based
on the new configuration data.
