2 SYSTEM DESCRIPTION

2.1 Introduction

Datex-Ohmeda S/5 monitors build up a freely configurable modular system. The architecture is designed to enable different module combinations so that the user is able to get the desirable parameter and feature set. This modular approach makes it possible to add new features when they are needed.

2.2 Bus structure

The operation of Datex-Ohmeda S/5 monitors is based on two communication channels, the CPU bus and the module bus. All boards connected to the CPU bus, as well as the parameter modules attached to the module bus, receive power from the same power supply, which is an integral part of the Central Unit, F-CU8.

				Controller		Supply

Module	Module	Module

The CPU bus is a parallel communication channel used only for internal data transfer between the boards connected to one Central Unit. It is based on the ISA bus used in IBM PC computers. Data is transferred on this 16 bit wide bus using the CPU clock frequency.

The module bus is used to connect the parameter modules to the Central Unit. It based on the widely used industry standard RS-485, which uses a differential serial method to transfer data. This type of bus is robust and it allows parameter modules to be inserted or removed whilst the power is on. The module bus uses a 500 kbps data transfer rate and can be used for longer distances than the CPU bus, e.g. for external frame connections.

Figure 2

General bus structure of S/5 system

The RS-485 type serial communication supports so-called multidrop or party line connections. This means that all parameter modules connected to module bus use the same two wires for communication purposes. The advantage of this is that all module bus connectors are identical and the parameter modules can be connected in any order and position.

2.3 Distributed processing

A system assembled from S/5 products is a multiprocessor system. All parameter modules have their own microprocessor, which performs low-level functions such as module key control, waveform filtering and pneumatic control, etc. At the same time the main CPU performs higher level tasks such as trending and alarm control. While the parameter modules and CPU are performing their tasks, the UPI (Universal Peripheral Interface) microprocessor handles all functions needed to

transfer data between the parameter modules and the CPU. At the same time the microprocessor on the Display Controller board performs pixel calculations for graphics.

This kind of parallel processing gives one major advantage to centralized processing. When new parameter modules or boards are added to the system, the processing power is increased. As a result, the system does not slow down when new features are added.

2.4 Module communication

The communication master controlling data transfers between the CPU bus and module bus is called the UPI Board. It sends information or questions to each parameter module 100 times per second. If the parameter module is present it replies to each question immediately by sending a data package back to the UPI board; the package length depends on the type of parameter module. This communication protocol ensures that each module receives and sends information every 10 ms. If the parameter module does not respond, the UPI board presumes that the module is not connected.

Each module type has a unique address, which the UPI board uses to send its messages. Two parameter modules of the same type must not be fitted to the same monitor system, otherwise they would both reply at the same time to the same message, resulting in an error.

Principle of UPI board operation

The microcontroller on the UPI board collects and stores all information sent from the parameter modules into a dual-port RAM which is mapped directly to the address space of the main CPU. The main CPU therefore reads information from its own memory whilst the UPI board guarantees that the information is up to date. This operation also works in the other direction. In this direction the main CPU fills the dual-port RAM with data and the UPI board microcontroller distributes it to the parameter modules.
