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 ensure that the CEX-Bus is correctly
connected, through the connector on the unit.
4. If BC810s are used, connect the TK851 cable to the two BC810s. 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 CEXBus 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).
5. Connect the RCU Data Link Cable (TK855) and the RCU Control Link Cable
(TK856) to both CPUs.
The RCU Data Link Cable (TK855) and the RCU Control Link Cable (TK856)
must not be replaced by similar cables. Using another cable will disable the
identification of the CPUs in the Control Builder and Operator Station.
The CPU connected to the RCU Control Link Cable (TK856) 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.

6. Provide connections for power supply and network:
a. Connect the power leads to screw terminals L+ and L- of both CPUs, and
the power supervision signals from SS8xx to screw terminals SA and SB.
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.
8. Provide battery backup by connecting the CPUs to the external SB822 battery
units. Install them according to the instructions in Installing the SB822
Rechargeable External Battery Unit on page 144.
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).

Section 2 Installation Installing the CEX-Bus without BC810
3BSE036351-510 A 97
Installing the CEX-Bus without BC810
The CEX-Bus, used for connection of communication interfaces to the processor
unit, is located on the left-hand side of the processor unit baseplate (TP830).
A bus termination unit must always be fitted to the last unit on the CEX-Bus, as
shown in Figure 25 on page 80. A TB850 male CEX-Bus termination unit is
supplied with each PM8xx/TP830 processor unit.
However, should the configuration require the use of a TK850 extension cable, as
shown in Figure 26 on page 81, then a TB851 female CEX-Bus termination unit is
required and must be fitted to the last baseplate in the sequence. A TB851 female
CEX-Bus termination unit is supplied with each TK850 extension cable.
TK850 CEX-Bus Extension Cable
Only one TK850 CEX-Bus extension cable may be used in any one CEX-Bus.
Cable length: 0.7 m (2.3 ft).
Installing the CEX-Bus Interconnection Unit BC810/TP857
The BC810 units must be mounted directly to the CEX-Bus on the processor unit
base plate. The SM810, if used, and communication interfaces are then mounted to
the CEX-Bus on the BC810, and terminated in each end with TB850 male CEX-Bus
termination unit. The two BC810 are connected with the interconnection cable
