  • Page 17: Section 2 - Description And Operation

    SECTION 2 - DESCRIPTION AND OPERATION INTRODUCTION The IMMFP12 Multi-Function Processor Module functions like a series of functional blocks working together. To explain how the MFP module works, this section shows MFP module func- tionality as a block diagram (refer to Figure 2-1) and then explains each block in the following text.

  • Page 18: Clock And Timer

    I/O data between control and I/O modules. It supports up to 64 low power I/O modules. The bus uses a protocol designed by Elsag Bailey to ensure data integ- rity. The bus bandwidth is 500 kilobytes per second, however actual throughput is about 100 kilobytes per second.

  • Page 19: Serial Channels

    32 connections. The Controlway interface is provided by a custom Elsag Bailey integrated cir- cuit that links the MFP module to the Controlway. It has full DMA capabilities (allowing for quicker operation), and two redundant, independent communication channels.

  • Page 20: Redundancy Link

    DESCRIPTION AND OPERATION ® There are two separate communication paths on the module mounting unit backplane circuit allotted for Controlway com- munications. Data is transmitted over both channels simulta- neously and received in separate receivers where it is checked for integrity. In this way, the Controlway minimizes the chances that a failure on a circuit board, or the backplane will cause loss of module communication.

  • Page 21: Section 3 - Installation

    SPECIAL HANDLING Observe these steps when handling electronic circuitry: NOTE: Always use Elsag Bailey field static kit (part number 1948385?1 - consisting of two wrist straps, ground cord assembly, alligator clip, and static dissipating work surface) when working with the modules.
