AS-BVIC-224模块备件

非SIL和SIL1-2应用不受SM811同步的影响。
它们在整个同步过程中继续正常执行
而不被中断。
SM811的热插拔要求两个安全模块与
同步链路，用于传输应用程序状态。
在热交换期间，无法从下载新配置
控件生成器，保留控制器。将通知控件生成器用户
具有信息对话框。当热插入时，将释放保留
结束或中止。如果正在进行配置下载，则热插入
下载完成后开始。

They continue to execute as normal throughout the entire synchronization
without being interrupted.
A Hot Swap of SM811 requires the two safety modules to be connected with a
synchronization link, used to transfer the application state.
During a hot swap it is not possible to download a new configuration from
Control Builder, the controller is reserved. The Control Builder user is notified
with an information dialog. The reservation is released when the hot insert is
concluded or aborted. If a configuration download is ongoing, then the hot insert
starts after the download is completed.

CI851 and TP851 – PROFIBUS DP Interface
Key Features
• Provides one PROFIBUS DP port, (a DB9 female
connector located on the TP851 Baseplate).
• Simple DIN-rail mounting
• The CI851 handles cyclic read and write messages
to the slaves on the PROFIBUS DP. The minimum
cycle time can be 1 ms, however, but this will
depend on the baud rate used and the number of
attached slaves.
• By using repeaters it is possible to connect a
maximum of 124 nodes to one PROFIBUS DP
(32 nodes are permitted on one segment).
• Pre-set, two-letter Alpha code locking device
installed in unit base prevents mounting of
incompatible components.
Description
CI851 / TP851 is used for connecting to remote I/O. Via
an external gateway on PROFIBUS DP, field instruments
(on PROFIBUS DP) can be connected to AC 800M. The
TP851 Baseplate has one female DB9 connector for
connecting PROFIBUS DP. The baseplate has a code
lock, see Table 4 on page 75, that prevents the installation of an incorrect type of
unit onto the TP851 Baseplate.
The CI851 expansion unit contains the CEX-Bus logic, a communication unit and a
DC/DC converter that supplies appropriate voltages from the +24 V supply, via the
CEX-Bus. The PROFIBUS DP must always be terminated at the two outer nodes.

ABB recommends the use of connectors with built-in termination since the fieldbus
will always be terminated even if fully disconnected from the unit.
