配置
在冗余配置中,安装了两个PM861/PM864/PM865/PM866单元
安装在两个单独的DIN导轨上。如果有足够的空间,单元可以
安装在同一DIN导轨上
使用以下步骤沿DIN导轨安装处理器单元:
1.安装处理器单元。
2.将通信接口安装在CEX总线左侧
处理器单元。如果使用BC810,则段的配置应为
考虑过的。如果未使用BC810,则接口可在
以任何优选方式提供两个CPU。
3.轻轻地将单元压在一起,确保CEX总线正确
通过基板上的连接器连接。
4.如果使用BC810,将TK851电缆连接到两个BC810(图31
100页)。如果未使用BC810,则安装CEX总线延长电缆TK850

直接安装到处理器单元上的CEX总线。CEX巴士
无论是否有任何CPU,扩展电缆必须连接到两个CPU
其他CEX总线单元(93页图29)。

The communication interfaces for PM891 is connected to the CEX-Bus to the
left of the processor unit. The S800 I/O units for PM891 is connected through
the optical ModuleBus at the bottom of the processor unit.
3. Re-insert the bus terminations into the communication units farthest from the
processor unit. For CEX-Bus, use the TB850 termination plug (TB851, if
CEX-Bus Extension cable TK850 is used. If no units are used on the CEX-Bus,
no bus termination is required.
4. Provide termination for redundancy, by using the termination plug
TB853 RCU Control Link Terminator, at the RCU Control Link connector at
the top of the processor unit.
5. Provide cable connections:
a. Connect the power leads to screw terminals L+ and L-. If applicable,
connect the power supervision signals from SS82x to the screw terminals
SA and SB.
b. Connect the Control Network cables to CN1 (single connection) or
CN1 + CN2 (redundant connection).
c. Connect the Control Builder to COM4 with cable TK212 (if required, for
changing an IP address). Otherwise connect the Control Builder to the
Control Network.

6. Connect the optical ModuleBus to the optical contacts (Tx1/Rx1) at the bottom
of the processor unit (see Figure 10 on page 43). For information regarding
optical cable selection and cable length, refer to the S800 I/O documentation.
7. Provide battery backup by connecting the PM891 unit to the external SB822
battery unit. Install it according to the instructions in Installing the SB822
Rechargeable External Battery Unit on page 144.
Communication Ports - CN1 and CN2
The control network connects to one or two RJ45 connectors (CN1 and CN2)
depending on network option (single or redundant).
Use an RJ45 connector for IEEE802.3 (Ethernet) for connecting to a category 5
Shielded Twisted Pair cable (STP class 5).
The connection to the optical ModuleBus is identical to that for the processor unit
and for the FCI in S800 I/O (see Figure 54 on page 160.)
Class 5, or higher, cable 10/100BaseT/TX max 100 m (110 yd). ABB recommends
the use of optical fiber in an industrial environment, for example 62.5/125
100BaseFX, max. distance 1500 m (1600 yd).

Installing the PM86x/TP830 Processor Unit in Redundant Configuration Section 2 Installation

Installing the PM86x/TP830 Processor Unit in Redundant
Configuration
In redundant configuration two PM861/PM864/PM865/PM866 units are mounted
onto two separate DIN-rails. If sufficient space is available, the units can be
mounted onto the same DIN-rail
Use the following procedure to install the processor units along the DIN-rail:
1. Mount the processor units.
2. Mount the communication interfaces on the CEX-Bus to the left of the
processor unit. If BC810s are used, the configuration of the segments should be
considered. If no BC810s are used, the interfaces can be divided between the
two CPUs in any preferred way.
3. Press the units gently together and make sure that the CEX-Bus is correctly
connected, via the connectors on the baseplates.
4. If BC810s are used, connect the TK851 cable to the two BC810s (Figure 31 on
page 100). If no BC810s are used, mount the CEX-Bus extension cable TK850
to the units at farthest away from the processor units or, if no units are
mounted, directly to the CEX-Bus on the processor unit. The CEX-Bus
extension cable must be connected to both CPUs whether or not there are any
other CEX-Bus units (Figure 29 on page 93).
This topic does not apply to the installation of PM891 unit in redundant
configuration. See Installing the PM891 Processor Unit in Redundant
Configuration on page 94.
Note that in redundant CPU configuration, COM3 and the electrical ModuleBus
on the baseplate can not be used.
