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

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
到离处理器单元远的单元，或者，如果没有单元
直接安装到处理器单元上的CEX总线。CEX巴士

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.

5. Connect the RCU Link Cable TK851 to both CPUs. Note that in redundant
CPU configuration, COM3 and the electrical ModuleBus on the baseplate can
not be used.
6. Baseplates cable connections:
a. Connect the power leads to both CPUs and the power supervision signals
from SS8xx to screw terminals SA and SB (see Figure 28 on page 83).
b. Connect the Control Network cables to CN1 (single bus connection) or
CN1 + CN2 (redundant bus connection). The Control Network is
connected to both CPUs.
c. Connect the Control Builder to COM4 with cable TK212 of the Primary
CPU (if required for changing an IP address etc.). Otherwise connect the
Control Builder to the Control Network.
7. Connect the optical ModuleBus to the optical contacts on the processor units
(see Figure 2 on page 32 and Figure 40 on page 131). Information regarding
optical cable selection and cable length is provided in the S800 I/O
documentation.
Note that the RCU Link Cable TK851 must be used and can not be replaced by a
similar cable. Using another cable will disable the identification of the CPUs in
the CB and Operator Station. When running in single configuration the RCU
Link Cable TK851 might temporarily be used to perform the function of a
termination plug.
The CPU connected to the RCU Link Cable connector marked “UPPER” will be
defined as “UPPER” in the Control Builder and Operator Station. The marking
has no relevance to the physical placement of the CPUs. Any CPU can become
the Primary CPU.
Both CPUs should be powered from the same supply (single or redundant). For
redundant power supply, see Figure 46 on page 140.
Connection to the optical ModuleBus is identical to that for the processor unit
and for the FCI in S800 I/O (Figure 55 on page 161).
