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.

Parameter 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 while 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.

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. 11 Document No. 8005796
