PM864/PM864A/PM865/PM866) with processor and Power Supply boards.
• Baseplate (TP830), housing the unit termination board.
For the Functional Block Diagram, see Figure 4 on page 35 and
Figure 5 on page 36. The CPU board contains the microprocessor and the RAMmemory, controllers for all built-in communication interfaces, real-time clock, LED
indicators, INIT push button and a Compact Flash interface.
The main function of the power supply board is to generate isolated, circuit-proof
+5 V and +3.3 V supplies to the CPU and I/O units. The board also contains optoisolated RS-232C drivers/receivers for the service port, together with a back-up
battery holder for memory/real time clock, (RTC).
The termination board, housed in the TP830 Baseplate, is where the majority of
the external connections terminates. The board is grounded to the DIN-rail through
of the metallic components of the housing. The termination board is provided with
screw terminals for power supply and redundant power supply monitoring, with
RJ45 connectors for the control network and serial port, a connector for the service
port, the electrical ModuleBus and the CEX-Bus.
The 24 V DC supply, connected to the TP830 Baseplate, powers all the units on the
CEX-Bus and the electrical ModuleBus.
In single CPU configuration, it is possible to connect an S800 I/O cluster directly to
the built-in electrical ModuleBus plug located on the right hand side of the TP830
Baseplate.
The processor unit has a communication expansion bus connector located on
the left-hand side of the TP830 Baseplate. This CEX-Bus provides for extending
the on-board communication ports with additional communication interfaces.

PROFIBUS DP, FOUNDATION Fieldbus H1, FOUNDATION Fieldbus High Speed
Ethernet and dual RS-232C ports are some examples of unit types available for
connection to the CEX-Bus. It is possible to use redundant communication
interfaces, for example PROFIBUS DP.
Figure 6 on page 38 provides examples of various ways to connect the S800 I/O
units. It can be seen, at the top right-hand area of Figure 6 on page 38, that one
cluster (or group) of units (maximum number of units per cluster is 12) is connected
to the electrical ModuleBus of an AC 800M Controller. However, a further seven
clusters (each comprising up to 12 units) can be added to the optical ModuleBus,
thus achieving a total count of 96 units per AC 800M Controller when using only
the ModuleBus.
To the left on Figure 6 on page 38, there is a PROFIBUS DP segment. This allows
for a large increase in the numbers of units connected to each AC 800M Controller.
Here the segment is shown as having an FCI unit (type CI801), connected to the
PROFIBUS DP network. The use of FCI units allows the selection of units from
several I/O families.
Figure 7 on page 39 shows another example for I/O units based on a
FOUNDATION Fieldbus High Speed Ethernet (FF HSE).
For further examples refer to the relevant documentation for the I/O system in
question.
Connecting S800 I/O units (using the ModuleBus) to an AC 800M Controller
mounted with a PM851/PM851A processor unit is restricted to, one electrical
ModuleBus cluster and one optical ModuleBus cluster
