HIMA X-SB01 985210207模擬量模塊
熱交換CI854A支持熱交換。它可以在線更換，不會對連接到CEX總線的其他單元造成任何干擾。在熱移除和隨后的插入之后，該單元將自動配置。在冗余配置中，可以在不干擾主單元的情況下更換備用單元。這包括如果設備出現(xiàn)故障，可以在線更換。為了支持熱交換，不需要配置。運行中的熱配置（HCIR）在運行中進行熱配置時，可以在線配置從屬設備，而無需初始化PROFIBUS通信。當循環(huán)通信保持活動時，新的或更改的配置被下載到從設備。如果從屬設備支持HCIR，則可以在線添加或刪除I/O單元。在重新配置期間，CI854/CI854A和從機之間的循環(huán)數(shù)據(jù)傳輸停止。CI854/CI854A保持輸入值，從機保持輸出值。在完成重新配置之后，循環(huán)數(shù)據(jù)傳輸將基于新的配置數(shù)據(jù)進行。
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.
