Installing the PM8xx/TP830 Processor Unit in Single
Configuration
Use the procedure below to install the processor unit along the DIN-rail:
1. If already mounted, remove the CEX-bus and ModuleBus terminations from
the sides of the processor unit.
2. Mount the processor unit, the communication interfaces and the S800 I/O units
(the communication interfaces on the CEX-bus to the left of the processor unit
and the S800 I/O units on the electrical ModuleBus to the right of the processor
unit).
3. Press them gently together and make sure that the ModuleBus and the CEX-
bus are correctly connected, via baseplate connectors.
4. Reinsert the bus terminations into the communication units at farthest away
from the processor unit.
a. For CEX-bus TB850 (TB851 if cable TK850 is used), see Figure 13 on
page 58 and Figure 14 on page 59. If no units are used on the CEX-bus, no
bus termination is required.
b. For ModuleBus TB807, refer to the S800 I/O documentation (see Related
Documentation on page 17). If no units are used on the ModuleBus, no
bus termination is required.
5. TP830 Baseplate cable connections:
a. Connect the power leads and, if applicable, power supervision signals
from SS822 to screw terminals SA and SB (see Figure 15 on page 60).
b. Connect the Control Network cables to CN1 (single connection) or CN1 +
CN2 (redundant connection).
c. Connect the serial protocol to COM3.
For PM861/PM864 insert the RCU Link Termination plug TB852, at the RCU
Link connector. The termination plug must always be used for PM861/PM864
when running in single configuration.
When a redundant processor is running in a single configuration use the RCU
Link Cable TK851, if the RCU Link Termination plug TB852 is not available.
