安装RS-232C接口，CI853/TP853
CI853由处理器单元通过CEX总线供电，因此不需要
额外的外部电源。
使用以下步骤安装CI853/TP853：
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.将电缆（大15米（16.4码））连接到
底板。将电缆屏蔽连接到接头内的接地端子
通过CI583将屏幕接地。
3.如果需要长度超过15米（16.4码）的电缆，则使用短距离调制解调器
必须使用TC562。在这种情况下，将调制解调器安装到DIN导轨上
在合适的位置，将24 V直流电源连接到调制解调器并连接
连接CI853和TC562调制解调器输入端子的TK853电缆
4.将TC562调制解调器输出端子连接到输出电缆。
TC562调制解调器可用于以下距离/速度：
•传输速度为19200比特/秒时，高可达1000米（1100码）
•传输速度为1200比特/秒，高可达12000米（13100码）

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CI852 has been replaced by the CI860 communication interface.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.

Installing the RS-232C Interface, CI853/TP853
CI853 is powered from the processor unit via the CEX bus and requires therefore no
additional external power source.
Use the following procedure to install the CI853/TP853:
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. Connect the cable (maximum 15 m (16.4 yd)) to one of the contacts on the
baseplate. Connect the cable screen to the ground terminal within the connector
to ground the screen via CI583.
3. If cables longer than 15 m (16.4 yd.) are required, then a short distance modem
TC562 must be used. In this case mount the modem onto a DIN-rail in a
suitable position, connect a 24 V DC power supply to the modem and connect
cable TK853 from CI853 to the TC562 modem input terminals
4. Connect the TC562 modem output terminals to the outgoing cable.
The TC562 modem can be used for the following distances/speeds:
• Up to 1000 m (1100 yd) with transmission speed 19200 bit/s
• Up to 12000 m (13100 yd) with transmission speed 1200 bit/s
Connectors
Connect the RS-232C channels to the RJ45 connectors marked COM1 and COM2
on the TP853 Baseplate.

Installing the PROFIBUS DP Interface,
CI854/CI854A/TP854
The CI854/CI854A is powered from the processor unit via the CEX-Bus and
requires therefore no additional external power source.
Use the following procedure to install the CI854/CI854A/TP854:
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 PROFIBUS DP cable. A connector with a switchable
built-in bus termination is recommended. Connect the cable screen to the metal
