Control Interface Module, Continued

Below is a summary of the basic functions performed by the CIM

assembly

CIM Operation

• Memory storage for the application database, analytical results,

programs, etc.

• Running Embedded Sensor Near Electronics (EMSNE) software

to control the sample analysis, acquire and process data from

detectors and control and monitor the analytical operating

environment.

• Performing data processing and calculations.

• Storing and executing MaxBasic programs.

• Providing a local user interface via the CIM Display.

• Communication via I

C bus to control internal hardware (PECM-

DC, EPC, DPM, I /O boards) and sending/receiving data.

• Optional control of Siemens Smart Sampling System

components via second I

C bus.

• Interface to external Ethernet and other network

communications.

• Interface via Serial ports (printer and Modbus).

The CIM display is a 10.4” color display with backlight manufactured by

Mitsubishi. It is controlled by software on the CIMBoard. Overlaid on top

of the display is the touch screen interface, also interfaced to the

CIMBoard. The touch screen is an 8-wire resistive custom touch screen

panel manufactured by Dawar. The touch screen is pressure sensitive,

meaning that it can be operated while wearing gloves or using an

appropriate stylus. Use of the display is described in Chapter 3 of this

manual.

Color Display and

Touch Screen

The Communication and Control board (CAC) is a standardized, single-

board central processing unit for intended for use in Siemens products.

For the Maxum family of products the third generation of the CAC board

(CAC3) is used, see figure 2-2. In the Maxum II Modular Oven

configuration, the CAC3 is mounted on the CIMBase board.

CAC3

The CAC3 contains the processor and memory functions for the CIM as

well as control of external Ethernet communications. The RJ-45 Ethernet

connection connects directly to the customer LAN. With the exception of

external Ethernet, the CIMBase contains all other interfaces provided by

the CIM assembly.
