安装基金会现场总线H1接口，
CI852/TP852
CI852由处理器单元通过CEX总线供电，因此需要：
没有额外的外部电源。FF H1总线上的现场设备未通电
来自CI852。
连接到CI852的AC 800M控制器构成基础
现场总线连接装置。
使用以下步骤安装CI852/TP852：
1.将装置安装到DIN导轨上，请参阅将AC 800M装置安装在DIN导轨上
在第65页，将PM86x/TP830处理器单元安装在单个
配置见第78页。
2.在基金会现场总线H1电缆上安装连接器。连接
将屏蔽电缆连接至接头内的接地端子，以将屏蔽接地
通过CI582。
3.将基金会现场总线H1电缆连接至底板上的触点。
基金会现场总线H1连接
将FF H1总线连接到位于TP852底板上的公DB9连接器。

CI851 has been replaced by the CI854 communication interface. CI851 is only
described for legacy reasons.
It is not possible to change the CI851 unit via hot swap and it is not allowed to
perform an online upgrade of firmware in a system containing CI851.

Installing the FOUNDATION Fieldbus H1 Interface,
CI852/TP852
CI852 is powered from the processor unit via the CEX-Bus and requires therefore
no additional external power source. No field device on the FF H1 bus is powered
from the CI852.
An AC 800M Controller connected to a CI852 constitutes a FOUNDATION
Fieldbus linking device.
Use the following procedure to install the CI852/TP852:
1. Mount the unit onto the DIN-rail, see Mounting AC 800M Units onto DIN-Rail
on page 65 and Installing the PM86x/TP830 Processor Unit in Single
Configuration on page 78.
2. Install a connector on the FOUNDATION Fieldbus H1 cable. Connect the
cable screen to the ground terminal within the connector to ground the screen
via CI582.
3. Connect the FOUNDATION Fieldbus H1 cable to the contact on the baseplate.
FOUNDATION Fieldbus H1 Connection
Connect the FF H1 bus to the male DB9 connector located on the TP852 Baseplate.
The use of shielded twisted pair cables for FOUNDATION Fieldbus is
recommended (see Appendix C, Recommended Components).

For additional information on designing a fieldbus (connectors, cables and devices),
see fieldbus documentation.
A catalog referencing suppliers, devices, services and other fieldbus-related items, is
available for FIELDBUS ONLINE via the Internet web site.
Powering Field Devices
Field devices requiring power from the fieldbus need special power supplies
connected to the data wires (in the same way as a field device). To avoid shortcircuiting of fieldbus signals, use only power supplies with impedance
characteristics specifically designed for FOUNDATION Fieldbus.
Do not use SD82x power supply units for this purpose.
Note that there is no unit redundancy for the CI852 unit.
Cannot be used in High Integrity Controller.
CI852 has been replaced by the CI860 communication interface. CI852 is only
described for legacy reasons.
It is not possible to change the CI852 unit via hot swap and it is not allowed to
perform an online upgrade of firmware in a system containing CI852.
