PM8xx/TP830处理器单元-概述
物理上，PM8xx/TP830处理器单元由两个基本部分组成：
•处理器单元
（PM851/PM851A/PM856/PM856A/PM860/PM86A/PM861/PM861A/
PM864/PM864A/PM865/PM866）。
•基板（TP830），用于容纳单元终端板。
有关功能框图，请参见35页图4和
图536页。CPU板包含微处理器和RAM、所有内置通信接口的控制器、实时时钟、LED
指示器、初始化按钮和紧凑的闪存接口。
电源板的主要功能是产生隔离的电路保护
+5V和+3.3V电源提供给CPU和I/O单元。该板还包含用于服务端口的光隔离RS-232C驱动器/接收器，以及一个备份
存储器/实时时钟（RTC）的电池支架。
安装在TP830基板中的终端板是
外部连接终止。电路板通过以下方式接地至DIN导轨：
外壳的金属部件。终端板配有：
用于电源和冗余电源监控的螺钉端子，带有
用于控制网络和串行端口的RJ45连接器，用于服务的连接器
端口、电气模块总线和CEX总线。
24 V直流电源，连接到TP830 BaseplWhen equipped with the specified Control Software, the AC 800M Controller acts
either as a stand-alone process controller, or as a controller performing local control
tasks in a control network consisting of many interconnected controllers, operator
stations and servers.
Various I/O systems can be connected to the AC 800M Controller, either directly
(S800 I/O) or via PROFIBUS DP or FOUNDATION Fieldbus.
The AC 800M is delivered without Control Software. To provide the controller
with Control Software, first load the firmware and then create the application
separately using the Control Builder M engineering tool.
The AC 800M Controller consists of a selection of units mounted on horizontal
DIN-rails, which can be housed within an enclosure. The majority of units consist of
a base mounting plate and removable cover attached with screws.
The baseplate, which is always mounted onto the DIN-rail, carries the majority of
the connections to processor, power supplies and communication interfaces, as well
as the connections to the external buses and systems.
The AC 800M Controller provides a cost-effective, low-maintenance solution for
applications ranging from small Programmable Logic Controller (PLC) to advanced
Distributed Control Systems (DCS) control applications and combined DCS, and
High Integrity systems control applications.
In the AC 800M High Integrity Controller, it is possible to run both non-SIL and
SIL classified applications. The AC 800M HI consist of PM865, SM810/SM811
and a High Integrity version of Control Software, and is also available in redundant
configuration. AC 800M HI requires the use of SIL certified S800 I/O units in SIL
Pclassified applications. If the application is not SIL classified, standard S800 I/O
units can be used with AC 800M HI controller.
Figure 1 shows the physical appearance of an AC 800M Controller with an
S800 I/O Unit. This physical appearance does not apply to PM891.
Figure 2 shows the PM861 processor unit that is part of the AC 800M controller.
This processor unit is different from PM891.

PM8xx/TP830 Processor Unit – General
Physically the PM8xx/TP830 Processor Unit consists of two basic parts:
• Processor Unit
(PM851/PM851A/PM856/PM856A/PM860/PM860A/PM861/PM861A/
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.
